Earth and Space Science Par 5 of 6
Study Guide
1. A solar system is a group of objects in space that move around a central star. (Our Sun)
2. A star is a burning sphere of gases. Our sun is a star.
3. The sun is the largest object in the solar system. The sun is larger than the rest of the objects in the solar system put together. The next largest object is Jupiter.
4. Some of the sun’s energy reaches the Earth as light and some reaches the Earth as heat.
5. The dark areas on the sun are called sunspots. They are cooler than the rest of the sun’s surface and don’t give off much light.
6. A planet is a large object that moves around a star. (There are 9 planets and they revolve around the sun.)
7. The time for one complete orbit by a planet around the sun is its year. It takes Earth 365 days to orbit the Sun. It takes Mercury 88 days to orbit the sun. It takes Pluto 250 Earth years to orbit the sun. Therefore, 1 Pluto year=250 Earth Years!
8. Moons are satellites that orbit a planet. All of the planets have at least one moon.
9. Asteroids and comets are other objects that move around the sun.
10. Asteroids are small and rocky. Some scientists believe that asteroids are pieces of a planet that never formed.
11. A comet is a small mass of dust and ice that orbits the sun in a long, oval-shaped path.
12. A Solar Eclipse occurs when the moon goes in front of the sun and blocks most of the sun's light from the earth. During a total eclipse all you can see from Earth is a ring of light around the moon which is part of the sun the moon did not cover.
