PPT-PLANETS LO: I will identify the known planets of the solar system.

SOLAR SYSTEM all of the planets 
moons comets and rocks that travel 
around the Sun GALAXY giant collection of gas dust 
and trillions of stars Milky Way our galaxy Planet Sizes PLANETS. The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars. Solar System:. The sun and all of the planets and other bodies that travel around it. Planet. A celestial body that orbits the sun, is round because of its own gravity, and has cleared the neighborhood around its orbital path. Chapter 23. Prentice Hall Earth Science. Touring Our Solar System.
