SPACE SCIENCE
Rotation and Revolution
Rotation: the act of an object spinning on its axis
Revolution: the path that all planets and smaller celestial objects make AROUND THE SUN or another object

Sun and Inner Planets
Sun: The luminous celestial body around which Earth and other planets revolve and receive heat and light
Planet: Any of the large celestial bodies that revolve around the Sun in the Solar System
Inner Planet: the four rocky planets closest to the Sun: Mercury, Venus, Earth, Mars
Outer Planet: the large, gaseous planets past the asteroid belt: Jupiter, Saturn, Uranus, Neptune
The Moon: the celestial satellite that orbits our planet
Asteroid: a small to large chunk of rock that typically orbits in an area between Mars and Jupiter, known as the Asteroid Belt
Comet: a body of rock and ice that travels around the Sun in an extreme elliptical path
Meteor: small chunks of iron and rock that travel through space, we see them as “shooting stars” as they burn up in Earth’s atmosphere. Occasionally, they hit Earth and their name changes to meteorite.
Galilean Moons: Jupiter’s four largest moons, named after their discoverer, Galileo Galilei. They are Io, Europa, Ganymede, and Callisto
THE SOLAR SYSTEM
Inner Planets- Rocky, Terrestrial- Small in comparison to the outer planets- Closer to the Sun
Mercury Venus Earth Mars
Outer Planets Gaseous Planets, no solid surface Largest Very spread apart Very far away from the sun
Size comparison of all planets
The whole Solar System!

Our Galaxy
The Milky WayIf we are in the Milky Way Galaxy, how can we see parts of it in the night sky?
Our location in the Milky Way
Why can’t we take a picture of our own galaxy?
How does Gravity fit in?So what do we know about gravity? We know that it causes any two objects in the universe to be drawn to one another. We know that gravity assisted in forming the universe and that it keeps the moon in orbit around the Earth.
