Revolution and RotationRevolution and Rotation
Revolve: the action of smaller Revolve: the action of smaller object circling around a larger object circling around a larger object in a pathobject in a path
Rotate: the action of a small Rotate: the action of a small object spinning and turning object spinning and turning around by itselfaround by itself
8 Known Planets8 Known Planets Inner planets: Mercury, Venus, Earth, and MarsInner planets: Mercury, Venus, Earth, and Mars Outer planets: Jupiter, Saturn, Uranus, and Outer planets: Jupiter, Saturn, Uranus, and
NeptuneNeptune The difference between outer planets and inner The difference between outer planets and inner
planets is that the distance from the Sun to outer planets is that the distance from the Sun to outer planets is longer than the distance from sun to planets is longer than the distance from sun to inner planetsinner planets
There are more craters found on inner planets There are more craters found on inner planets than the outer planets because outer planets than the outer planets because outer planets have rings. Also, the Sun has a lot of gravity that have rings. Also, the Sun has a lot of gravity that keeps the asteroids and meteorites revolving keeps the asteroids and meteorites revolving around.around.
