| Question | Answer |
|---|---|
| Mean Distance | The average distance between a planet and the sun. |
| Period of Revolution | The time it takes a planet to revolve or orbit around the sun (go around sun). |
| Period of Rotation | The time it takes a planet to complete one spin on its axis. |
| Eccentricity of Orbit | Describes the shape of the orbit (path of a planet around the sun). The higher the number the more oval (eccentric) the orbit. |
| Equatorial Diameter | Explains the size of the planet by measuring the equatorial diameter. |
| Mass | The amount of matter found within a planet. |
| Density | The amount of matter within an occupied space. |
| Terrestrial Planets | Planets-Mercury, Venus, Earth, Mars (The first four planets/inner planets) Characteristics: Rocky/earthlike Very dense Small in size |
| Jovian Planets | Planets: Jupiter, Saturn, Uranus, Neptune (Outer planets) Characteristics: * Gaseous * Very large (equatorial diameter) * Low density * More massive |
| Asteroid Belt | The asteroid belt is located between Mars and Jupiter. This belt separates the Terrestrial and Jovian planets. |
| Mercury | Terrestrial planet Smallest Fastest period of revolution No atmosphere |
| Venus | Terrestrial Planet Hottest planet due to runaway greenhouse effect. Toxic atmosphere |
| Earth | Terrestrial Planet Only planet that has liquid water. Most dense planet |
| Mars | Terrestrial Planet Called the Red Planet (metal within soil has rusted/oxidized). |
| Asteroid Belt | Found between Mars and Jupiter. The asteroid belt separates Terrestrial and Jovian planets. |
| Jupiter | Jovian Planet Largest planet Fastest period of rotation which creates hurricane type winds on planet. |
| Saturn | Jovian Planet 2nd largest planet. Least dense planet. |
| Uranus | Jovian Planet 3rd largest planet Rotates on its side like a bowling bowl. |
| Neptune | Jovian Planet 4 largest planet Takes 164.8 years to revolves around the sun. |
| Dwarf Planets | Pluto Eris Ceres |
| Comet | * Known as a dirty snowball. * Made of dust particles trapped in a mixture of frozen water, carbon dioxide, methane and ammonia. |
| Asteroid | Huge, solid, rocklike masses Leftover material from the solar system's formation. |
| Meteoroids | Meteoroids (celestial object) are different than asteroids because they are smaller in size. |
| bolide? | Impact Crater: As a bolide strikes the earth it leaves a crater behind. |
| Kuiper Belt | The Kuiper Belt is a disk-shaped region of icy bodies located beyond the orbit of Neptune. |
