| Solar System | The Sun together with the group of planets and other celestial bodies that are held by its gravitational attraction and revolve around it |
| Gravity | The force that causes objects with mass to attract one another |
| Orbital Path | The gravitationally curved path of an object around a point in space |

| Rocky | Made of rocks |
| Terrestrial | Earth-like |
| Outer Planet | Any of the planets Jupiter, Saturn, Uranus, and Neptune, whose orbits lie beyond the asteroid belt |
| Asteroids | Large and small rocks or metallic masses orbiting the Sun; made up of materials similar to those that formed the planets |
| Asteroid Belt | The region between the inner and outer planets where most asteroids orbit around the Sun |
| Meteoroid | A natural chunk of rock or dust existing outside of Earth’s atmosphere |
| Meteor | A small object that enters Earth’s atmosphere from space and burns due to friction, thus emitting light |

| Moon | A celestial body that revolves around a planet |
| Comet | A celestial body of ice, dust, and rock with an elongated and elliptical orbit |
