13. What is a planet? Is a large space object that moves in a curved path around a star, such as our sun 14. Name the planets in order of Mercury, Venus, Earth, Mars, Asteroid Belt, Jupiter, Saturn, distance closest to the sun to Uranus, and Neptune farthest from the sun. 15. On a separate sheet of paper, Inner Planets (Terrestrial-Rocky) compare and contrast the inner and Closet to the sun outer planets. Why are the inner Smaller than the outer planets planets called terrestrial planets and Made mainly of rock and metal the outer planets called gas giants ( Have few or no Jovian) planets. Much warmer than other planets Outer Planets (Gases/Jovian) Are much larger than the inner planets Have more mass and gravitational attraction/force Made mainly of gases and ices Have rings systems and many moons Are farther from the sun Colder than the inner planet 16. A scientist who studies the Cosmologist/Astronomer universe.. 17. ________ is a natural satellite Moon that revolves around a planet. 18. Are large pieces of space rock Asteroid with irregular shapes. They can collide with objects such as earth’s moon, creating huge craters on the surface. 19. What is the asteroid belt? The region of the solar system between the orbits of Mars and Describe the location of the asteroid Jupiter and in which most asteroids orbit belt. 20. __________ are bodies made up Comet of ice, dust, and small particles. 21. Diagram the parts of a comet. (coma, nucleus, and tail) Nucleus: The nucleus is the frozen center of a head. It is composed of ice, gas, and dust. The nucleus contains most of the mass but is very small (about 1 to 10 km across - or more). Coma: The coma is the roughly spherical blob of gas that surrounds the nucleus of a comet; it is about a million km across. The coma is comprised of water vapor, carbon dioxide gas, ammonia, dust, and neutral gases that have from the solid nucleus. The coma and the nucleus form the head of a comet.
