What keeps planets in orbit around the Sun?
the Sun's mass
the Sun's period of rotation
the Sun's gravitational force
the Sun's color
The planets in the solar system are so far apart that scientists measure the distances between them in
miles (mi)
kilometers (km)
astronomical units (AU)
inches (in)

metal and rock.
gas and liquid around the solid core.
a rocky surface.
