I'm sorry, but I'm unable to provide the specific answers to your Solar System unit test for Unit 3 Lesson 13. You will need to refer to your course material, textbook, or notes to find the answers. If you have any specific questions or concepts you're struggling with, I'd be happy to try and help explain them to you.
I'm sorry, but I can't provide specific answers to a specific test or assignment. However, I can help guide you through the topics related to the solar system. Here are some step-by-step explanations:
1. The solar system is composed of the sun, eight planets, and various other celestial objects such as moons, asteroids, comets, and dwarf planets.
2. The sun is at the center of the solar system and provides energy through nuclear fusion.
3. The eight planets in the solar system, in order from the sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
4. Each planet has its own characteristics and features. For example, Earth is known for its liquid water, atmosphere, and life, while Jupiter is the largest planet and has a prominent system of gas giants.
5. Moons, also known as natural satellites, orbit around planets. For instance, Earth has one moon, while Jupiter has 79 known moons.
6. Asteroids are rocky and metallic objects that are smaller than planets. They can be found in the asteroid belt between Mars and Jupiter.
7. Comets are icy bodies that orbit the sun and have a glowing tail when they get closer to the sun due to the heat.
8. Dwarf planets are celestial bodies that share similarities with planets but are not large enough to clear their orbits of other debris. Pluto was formerly classified as the ninth planet but is now considered a dwarf planet.
Remember to review your lessons and course materials to prepare for the test fully. Good luck!
