The document discusses key facts about our solar system including the eight planets, with four rocky inner planets and four gas outer planets. It describes the sun's temperature and role in sustaining life on Earth. Details are provided about Earth's size, distance from the sun, composition, and three motions of spinning daily, orbiting the sun yearly, and moving through the Milky Way. The causes and diagrams of the seasons due to Earth's tilted axis are explained. Facts provided about the moon include that it does not produce its own light but reflects the sun's, is much smaller than Earth, and has no atmosphere or life. Phases of the moon and the cycle of night and day are also summarized.
The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. We observe different stars in the sky at different times of the year.

This is a PowerPoint that is about Exploring Earth Science. This is geared towards 3rd grade students. This is very picture heavy so it will easily keep the attention of young children. It is also full of helpful information
A digital story about the universe, solar system, the sun, characteristics of the sun, the earth, characteristics of the earth and inner and outer planets of the solar system.

While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal

Professor’s Questions Set 5
Provide comprehensive answers to the following questions. Remember to support your arguments where necessary by websites and pictures.
Chapter 7 and 8 Readings
1. Why is Jupiter so much richer in hydrogen and helium than Earth?
2. Why do astronomers conclude that none of the Jovian planets’ rings can be left over from the formation of the planets?
3. How can Jupiter have a liquid interior and not have a definite liquid surface?
4. Why are Uranus and Neptune respectively green-blue and blue?
5. What evidence indicates that catastrophic impacts have occurred in the solar system’s past?
6. Why do astronomers refer to carbonaceous chondrites as unmodified or “primitive” materials?
7. What evidence indicates that the asteroids are mostly fragments of larger bodies?
8. What is the difference between condensation and accretion?
9. Why does the solar nebula theory predict that planetary systems are common?
10. Why is the evidence of “hot Jupiters” puzzling? What is the current hypothesis of how they formed?

Origin of the Solar System and Extrasolar Planets
*
The solar system is our home in the universe. As humans are an intelligent species, we have the right and the responsibility to wonder what we are. Our kind has inhabited this solar system for at least a million years. However, only within the last hundred years have we begun to understand what a solar system is.
*
You are linked through a great chain of origins that leads backward through time to the first instant when the universe began 13.7 billion years ago.The gradual discovery of the links in that chain is one of the most exciting adventures of the human intellect.
The Great Chain of Origins
*
Earlier, you have studied some of that story:Origin of the universe in the big bangFormation of galaxiesOrigin of starsProduction of the chemical elementsHere, you will explore further and consider the origin of planets.
The Great Chain of Origins
*
By the time the universe was three minutes old, the protons, neutrons, and electrons in your body had come into existence. You are made of very old matter.
The History of the Atoms in Your Body
*
Although those particles formed quickly, they were not linked together to form the atoms that are common today.Most of the matter was hydrogen and about
25 percent was helium. Very few of the heavier atoms were made in
the big bang.
The History of the Atoms in Your Body
*
Although your body does not contain helium, it does contain many of those ancient hydrogen atoms that have remained unchanged since the universe began.
The History of the Atoms in Your Body
*
During the first few hundred million years after the big bang, matter collected to form galaxies containing billions of stars. You have learned how nuclear reactions inside stars combine low-mass atoms, su ...
2. Our solar system! *Eight Planets *4 Rocky Planets: Mercury, Venus, Earth, and Mars *4 Gas Planets: Jupiter, Saturn, Uranus, and Neptune *Moons, comets, asteroids, and dust
3. The Sun *About 5,000 Celsius! *Sustains all life on Earth *Closest star to the Earth
