Asteroids are small airless rocky bodies that orbit the sun but are too small to be considered planets. Most asteroids lie within the vast asteroid belt between the orbits of Mars and Jupiter. There are different types of asteroids classified based on their orbits, including those in the main asteroid belt and near-Earth asteroids whose orbits bring them closer to Earth.

Comets, Asteriods, and Meteors
Recent advances in space technology have allowed scientists from different fields to collaborate on studying Near-Earth Objects like comets and asteroids. Both comets and asteroids provide clues about the origins of our solar system. Several asteroids have been discovered to come close to Earth in recent years, including Asteroid 2012 DA14 which had a very close approach in February 2012. Impacts from asteroids and comets have affected Earth in the past and could cause catastrophic effects if a large one collided with Earth, though such collisions are rare.
Other members of solar system
Asteroids occupy the large gap between Mars and Jupiter. Comets are small bodies that orbit the sun in elongated orbits and have tails. Halley's Comet appears every 76 years. Meteors are small objects that burn up when entering Earth's atmosphere, appearing as shooting stars. Meteor showers occur when Earth passes through comet debris. Some large meteors survive entry and are called meteorites. Satellites are natural or artificial objects that orbit Earth or other planets. Artificial satellites have practical applications like weather forecasting and telecommunications.

There are several other objects in our solar system besides planets. Asteroids occupy the large gap between Mars and Jupiter, while comets revolve around the sun in elongated orbits and have tails. Comets can be short or long period, and Halley's Comet returns about every 76 years. Meteors are small objects that burn up as they enter the Earth's atmosphere, leaving trails called shooting stars. Meteor showers occur when the Earth passes through comet debris. Larger meteors can survive entry and are called meteorites. Satellites are objects that orbit Earth or other astronomical bodies, with artificial satellites being human-made and launched from Earth for uses like weather forecasting, communications, and remote sensing.
COMETS,ASTEROIDS, AND METEORS
Comets are small icy objects with two tails made of gas and dust that formed over 4.6 billion years ago in the early solar system and have highly elliptical orbits. Asteroids are small rocky or metallic objects that orbit the sun, ranging in size from meters to hundreds of kilometers wide with irregular shapes and cratered surfaces. Meteors are streaks of light seen when meteoroids - space rocks or fragments that can be from comets, asteroids, moons or Mars - enter the Earth's atmosphere. Some meteoroids survive entry and land on Earth's surface as meteorites.
Asteroids, comets, meteors, and moons
Comets are small cosmic bodies composed of rock, dust, ice and frozen gases that orbit the sun in elongated orbits. They develop tails and comas as solar radiation causes particles to dissipate from the comet as they approach the sun. Asteroids are small rocky bodies that orbit the sun and are remnants of larger planetesimals. Meteoroids are smaller particles that orbit the sun and create visible meteors when entering Earth's atmosphere due to pressure.

Comets, Asteroids, And Meteors
Comets are chunks of ice and dust that orbit the sun in elongated elliptical orbits, with a nucleus and coma forming the head and a tail always pointing away from the sun. Asteroids are smaller rocky objects found predominantly in the asteroid belt between Mars and Jupiter. Meteors are space rocks or dust that burn up as streaks of light upon entering Earth's atmosphere, with meteorites being those that survive impact with the surface.
asteriods, meteors and comet
This document discusses deep sky objects such as asteroids, meteorites, and comets. It provides information on what asteroids are made of and where they are located in the asteroid belt between Mars and Jupiter. Meteorites are pieces of asteroids or comets that have fallen to Earth. Comets are described as "dirty snowballs" made of dust, ice, and rock that originate from the Oort cloud or Kuiper belt and have tails pointing away from the Sun. Examples of famous comets like Halley and comets that have impacted planets like Jupiter are mentioned. The differences between asteroids, meteorites, and comets are summarized.
Asteroids and meteorites
Asteroids orbit the sun and are smaller than planets but larger than meteoroids. They formed in the asteroid belt between Mars and Jupiter but gravitational forces prevented them from forming a planet. Meteorites originate from asteroids and comets and survive atmospheric entry and impact, appearing as meteors and shooting stars. Ceres was the first asteroid discovered and is located in the asteroid belt, while asteroids can be classified based on their composition such as chondrites, achondrites, iron, and stony-iron meteorites.
Report
Asteroids are small planets that revolve around the sun between Mars and Jupiter. They are divided into large asteroids like Ceres, Pallas, Vesta and Hygiren and small asteroids such as Eros, Hitos, and Geografos. Asteroids formed from the coagulation of planetesimals during the formation of the eight main planets and their satellites in the early solar system. The first asteroid, Ceres, was discovered in 1801 by a Sicilian clergyman.
The Comets, Meteors and Meteorites by Carolyn Grande (I made)
Comets are icy members of the solar system that orbit the sun in elliptical orbits. They likely formed from the original material from which the solar system was created 5 billion years ago, making them some of the oldest objects in the solar system. Comets have three main structures - the icy nucleus, a coma of evaporated gases that surrounds the nucleus, and one or two tails that always point away from the sun due to radiation pressure and solar winds. Comets originate from two regions in the outer solar system - the Kuiper Belt and the distant Oort Cloud. The most famous periodic comet is Halley's Comet, which orbits the sun every 76 years.
Comets, asteroids, meteors
Comets are made of dust, rock and frozen gases that vaporize as they near the Sun, forming a coma and tail. Comets eventually break apart after passing by the Sun multiple times. Small pieces of comets are called meteoroids, which appear as meteors or "shooting stars" when burning up in Earth's atmosphere, or meteorites if they reach the ground. Asteroids are rocky bodies like planets that mainly orbit in a belt between Mars and Jupiter.

About our universe
The universe began with the Big Bang approximately 13.8 billion years ago. Our solar system formed 4.6 billion years ago from a giant cloud, and consists of the Sun and objects that orbit it, including eight planets. The four inner terrestrial planets are made of rock and metal, while the four outer gas giants are mostly hydrogen and helium. The Sun is a star that is about 109 times the size of Earth and made of hydrogen and helium. It rotates faster at its equator than its poles. Planets orbit stars and are rounded by gravity, while dwarf planets are smaller bodies that have not cleared their orbits. Earth is the third planet from the Sun and the only known place where life has evolved, developing
Comets, Asteroids, Meteors, and the Moon
Comets are small icy objects that orbit the sun and have tails made of dust and gas. When comets get close to the sun, their ice melts and forms tails. Asteroids are smaller than comets and are made of rock rather than ice. They orbit in the asteroid belt between Mars and Jupiter. Meteoroids enter Earth's atmosphere and burn up, appearing as streaks of light called meteors. If they survive entry and hit the ground, they are called meteorites.
Asteroids and comets
This document discusses debris in our solar system and its importance in understanding the origin and evolution of the early solar system. It provides an overview of asteroids, meteorites, comets, and impact craters on Earth. Evidence suggests an asteroid or comet impact was responsible for the extinction of dinosaurs 65 million years ago. The study of solar system debris holds keys to deciphering the history of our solar system.
Solar system
This document provides an introduction to the solar system, including planets, the sun, moon, asteroids, meteoroids, and comets. It explains that planets orbit the sun and can be categorized into rocky planets like Earth or gas planets. It also gives some details about the sun, stating that it lies at the heart of the solar system, formed from a cloud of gas and dust around 5 billion years ago, and continues providing light and heat to Earth and the solar system.
Comets and asteroids
This document provides information about comets and asteroids. It defines a comet as a small solar system body that displays a coma and sometimes tail when close to the sun due to solar radiation. Comet nuclei range from hundreds of meters to tens of kilometers and are made of ice, dust, and small rocks. The document discusses how Edmond Halley correctly hypothesized that the comets of 1456, 1532, 1607 and 1682 were the same object, now known as Halley's Comet, and how it returns every 75-76 years. It also mentions that the impact of a 10km asteroid may have caused the extinction of dinosaurs 65 million years ago based on geological evidence.
Other members of solar system
Comets, asteroids, meteoroids, and meteorites are different types of small solar system bodies. Comets are icy bodies that develop tails as they heat up when passing near the sun. Asteroids orbit the sun and most reside in the asteroid belt between Mars and Jupiter. Meteoroids are smaller objects that enter the earth's atmosphere and are called meteors when burning up in the sky. Those that survive entry and hit the ground are meteorites.
Earth science 23.4
This document summarizes minor members of the solar system including asteroids, comets, meteorites, and meteoroids. Asteroids are small rocky bodies that mainly orbit between Mars and Jupiter. Comets are small icy bodies that travel in elongated orbits around the sun and develop comas and tails as they near the sun. Meteorites are pieces of meteoroids that survive entry into Earth's atmosphere and reach the surface, while meteoroids are small solid particles that travel through space and become meteors or "shooting stars" when entering Earth's atmosphere.
Asteroids and meteoroids
Asteroids are spread far apart in the asteroid belt, making collisions unlikely. They formed from collisions of early planetary bodies. Most asteroids have a covering of dust called regolith. While planets have large moons, some asteroids also have small moons. Asteroids group together in the main belt, Kuiper belt, as Trojans, or in the scattered disc. Meteoroids range in size from dust grains to baseballs and the largest may be asteroid fragments. Meteor showers occur when Earth passes through debris left by comets. There are about 9 major annual meteor showers.
Comet [autosaved]
The document provides information on 20 comets, including Halley's Comet, Comet McNaught, Comet Hyakutake, Comet Borrelly, Hale-Bopp Comet, Comet Chiron, Comet Wild 2, Comet Tempel-Tuttle, Comet Encke, Shoemaker-Levy 9, Comet Churyumov-Gerasimenko, Comet Leonard, Comet 103P/Hartley, Comet Donati, Comet Kohoutek, 'Oumuamua, Comet PanSTARRS, and others. It describes attributes like orbital period, size, discovery date, and notable appearances or impacts for each comet.

KGrothe -ASAT2016-DefendingEarth
The document discusses the threat posed by asteroids impacting Earth and various methods for detecting and defending the planet from asteroids. It notes that while the threat to any individual is low, the risk over long periods of time is not negligible. As such, efforts are underway to detect asteroids through programs like NASA's NEO Program and track their motions to understand the risk. If an asteroid is determined to pose an impact threat, various defensive techniques are proposed, including deflecting asteroids using laser beams, nuclear weapons, or kinetic impactors to alter the asteroid's path away from Earth. International efforts aim to both detect potentially hazardous asteroids and develop impact mitigation strategies.

The report reviews the threat posed by Near Earth Objects and proposes solutions to improve detection and mitigation capabilities. It finds that current detection systems are inadequate to provide warning for high inclination objects. Deflection using nuclear devices is the only option for such threats, but appropriate infrastructure is lacking. An international committee, the INEOC, is proposed to coordinate detection efforts and focus discussion on mitigation techniques and command and control. Improving detection technologies to begin deflection measures earlier is key to increasing the probability of a successful mitigation mission. International cooperation is vital for a long-term effort to defend Earth from potential impacts.
Shield
This document proposes SHIELD, a comprehensive system to detect and mitigate threats from Earth-impacting asteroids and comets. It consists of space-based detection sentries in Venus-orbit to continuously scan the skies and detect potential impactors. Once detected, soldiers stationed in Venus-orbit could be deployed to characterize the object and, if needed, rendezvous with it to deflect its trajectory using techniques like kinetic impactors, nuclear detonations, or solar sails. The system aims to provide early detection to enable a gradual deflection years in advance using minimal energy. It argues starting development now is prudent given the threat.

Recent advances in space technology have allowed scientists from different backgrounds to collaborate on studying Near-Earth Objects like comets and asteroids. Studies of these objects provide clues about the origins of the solar system. Several asteroids have been discovered to come close to Earth in recent years, including Asteroid 2012 DA14 in February 2012. Impacts from asteroids and comets have significantly affected Earth in the past, including possibly causing the extinction of dinosaurs 65 million years ago. On average, objects large enough for an impact are estimated to hit Earth once every 100,000 years or so, with smaller objects hitting more frequently.

- 1. Reporter By: Baldeconza, Eio M.
- 2. Are small, airless rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. Most asteroids lie in a vast ring between the orbits of mars and jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter.
- 3. Main belt Near Earth Asteroids Atens Appollos Amors Trojans
- 5. Is an astronomical object in direct orbit the sun that is neither a planet nor exclusively classified as comet.

- 9. Is the largest object in the asteroid belt that lies between the orbits of Mars & Jupiter. Its diameter is approximately 945 kilometer or 875miles.
- 10. Was an italian Catholic priest of the Theatine Order, mathemetician & astronomer. Perhaps his most famous discovery was the 1st dwarf planet is CERES.
- 11. Is noted for its history, culture, architecture & gastronomy.
- 12. The 4 terrestrial or innermost planets have dense, rocky compositions, few or no moons & no ring systems, they are composed largely of refractory minerals , such as the silicates, which form their crusts & mantles & metals, such as iron & nickel, which from their cores. Planetoids is another term for asteroids, which are also called MINOR PLANETS. Planetoids are small celestial bodies that orbit the sun.
- 13. Asteroids-planetoids; were discovered in 1801, & manymore have been discovered since then up until 1977, almost all the asteroids discovered were near JUPITER. Some of the largests planetoids are spherical & look like tiny version of PLANETS. Most Planetoids are in region called the ASTEROID BELTS which is situated between MARS & JUPITER. There are millions of Planetoids in this Region.
- 14. This model, known as the Nebular Hypothesis, was 1st developed in the 18th century by Emmanul Swedenburg, immunel Kant & pierre Simon Laplace
- 15. Is the Circumstellar disc in the Solar System located roughly between the planets MARS & JUPITER.
- 16. Are populations that share an orbit with larger planet or moon.
