Solar and Heliospheric Observatory (SOHO)Surface temp- 10000 degrees farenheitThe connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, and climateAbout one million Earths could fit inside the Sun
Energy from the core is carried outward by radiation, which bounces around the radiative zone, taking about 170,000 years to get from the core to the convective zone. The temperature drops below 2 million degrees Celsius (3.5 million degrees Fahrenheit) in the convective zone, where large bubbles of hot plasma (a soup of ionized atoms) move upwardsThe biggest stars are about 1600 times the size of our SunThe area of the Sun’s influence stretches far beyond the planets, forming a giant bubble called the heliosphere. The enormous bubble of the heliosphereis created by the solar wind, a stream of charged gas blowing outward from the Sun. As the Sun orbits the center of the Milky Way, the bubble of the heliosphere moves also, creating a bow shock ahead of itself in interstellar space — like the bow of a ship in water — as it crashes into the interstellar gases. The area where the solar wind is abruptly slowed by pressure from gas between the stars is called the termination shock.
Has the shortest orbit in the Solar System.Messenger MissionMercury takes 59 days to make a rotation but only 88 days to circle the Sun.Mercury is only about one-third the size of the Earth.Mercury's atmosphere is very thin Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin.
Pioneer Venus mission, now over.Venus is referred to as the Evening Star because it is the brightest planet that can be viewed from Earth. Venus and Earth are similar in size, composition, and mass.Its temperature during the day reaches 484 degrees Celsius, which is hot enough to melt LEAD.The dense atmosphere is composed of carbon dioxide and sulfuric acid which acts as a greenhouse and traps the heat.
Three quarters of the Earth is covered by waterEarth rotates on an imaginary axis which is tilted at a 23.5 degree angle.The tilt is what determines our change in seasons.Earth has a core of iron and nickel. Earth has one naturally occurring satellite, the Moon.
The Moon rotates on its axis in around the same length of time it takes to orbit the Earth. This means that from Earth we only ever see around 60% of its surface (50% at any one time).The side that we can see from Earth is called the near side while the other side is called the far side (it is sometimes called the dark side despite the fact that it illuminated by the Sun just as much as the near side).The phases of the Moon are: New Moon, Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Crescent,
Curiosity, the Mars science laboratoryMars is the home of "Olympus Mons", the largest volcano found in the solar system and the HIGHEST PEAK IN THE SYSTEMAlso home to Victoria Crater, the DEEPEST VALLEY in the systemThe presence of iron explains the planet's reddish-orange appearanceMars has two small natural satellites, Phobos and Deimos.
Asteroids, sometimes called minor planets, are small, rocky fragments left over from the formation of the solar system about 4.6 billion years agoThe total mass of all the asteroids is less than that of the Moon.Because asteroids have remained mostly unchanged for billions of years, studies of them could tell us a great deal about the early solar systemNASA is planning for a robotic spaceship to lasso a small asteroid and park it near the moon for astronauts to explore, a top senator said Friday.The ship would capture the 500-ton, 25-foot asteroid in 2019. Then using an Orion space capsule, a crew of about four astronauts would nuzzle up next to the rock in 2021 for spacewalking exploration
Has the largest moon in the Solar System – Ganymede. Juno Space MissionLightning, more powerful than any that has been experienced on Earth, has been noted in Jupiter's atmosphere.The Great Red Spot is a hurricane-like storm that has been seen in Jupiter's southern hemisphere since Jupiter was first discovered.Jupiter is surrounded by a system of thin rings. The majority of the rings are made up of very small particles thought to be debris from meteoroid collisions.
Cassini missionSaturn is the second biggest planet, but it’s also the lightest planet.Saturn has the lowest density of any planet in our solar system.The winds in Saturn's atmosphere reach speeds up to 1800 kilometers per hourAstronomers believe the rings developed from particles that resulted from the break-up of naturally occurring satellites.
Uranus’ axis is at a 97 degree angle, meaning that it orbits lying on its sideThe temperature in the upper atmosphere is so cold that the methane condenses and forms a thin cloud layer which gives the planet its blue-green appearance.Uranus has a very strong magnetic field.This planet has a system of rings which was not discovered until 1977
Neptune was discovered in 1846Voyager 2, a space probe, passed within 4900 kilometers of Neptune in 1989.The largest satellite is Triton.Neptune has large, dark ovals on its surface which astronomers believe are hurricane-like storms.
New Horizons mission will study Pluto and it’s moonThe Voyager Mission revealed that Saturn is not the only planet with rings, Jupiter, Uranus, and Neptune all have rings as wellIt is tasked with locating and studying the boundaries of the Solar System, including the Kuiper belt, the heliosphere and interstellar space. Each Voyager space probe carries a gold-plated audio-visual disc in the event that either spacecraft is ever found by intelligent life-forms from other planetary systems.[6] The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from the people (e.g. the Secretary-General of the United Nations and the President of the United States, and the children of the Planet Earth) and a medley, "Sounds of Earth", that includes the sounds of whales, a baby crying, waves breaking on a shore, and a variety of music.The outer extent of the Oort Cloud is considered to be the “edge” of our solar system, where the Sun’s physical and gravitational influence ends.The objects in the Oort Cloud and in the Kuiper Belt are presumed to be remnants from the formation of the solar system about 4.6 billion years ago.
The Voyagers are still operational after more than 15 years in space and are traveling out of the Solar System. Both Voyagers are using their ultraviolet spectrometers to map the heliosphere and study the incoming interstellar wind.
