Is a body that orbits a planet.

Is a giant ball of superheated gas, or plasma, composed of hydrogen and helium.

Spherical, orbits the sun, with a larger mass than nearby objects.

Is a streak of light produced when a small piece of rock or ice, known as a meteoroid, burns up as it enters earth’s atmosphere.

Is a cold mixture of dust and ice that develops a long trail of light as it approaches the sun.

The spinning of Earth on it’s axis.

Is the movement of one object around another.
