Inner Planets • Closest to the sun • Small and rocky • Few or no moons • Mercury • Venus • Earth • Mars
Mercury • Appearance/terrain-Covered with craters that created when meteors crashed into it. • Diameter- 4,880 km (2nd smallest planet) • Distance from the Sun- 57.9 million km (36 million miles) • Temperature: very hot daytime, very cold night • Length of 1 day: 58 Earth days • Length of 1 year: 88 Earth days • # of moons: 0
Venus • Appearance/terrain- very similar to earth with mountains, continents, and even areas where oceans could be (if there were any water). • Diameter- 12,100 km • Distance from the Sun- 108 million km (67 million miles) • Temperature: thick atmosphere traps gases making it the hottest planet. • Length of 1 day: 243 Earth days • Length of 1 year: 224 Earth days • # of moons: 0
Earth • Appearance/terrain- Mostly blue(3/4 water), brown and green continents and white ice-capped poles. • Diameter- 12, 756 km • Distance from the Sun- 150 million km (93 million miles) • Temperature: varies by location • Length of 1 day: 24 hours • Length of 1 year: 365 ¼ days • # of moons: 1
Mars • Appearance/terrain- Very rocky, red colored soil because of large amount of iron. • Diameter- 6,800 km • Distance from the Sun- 250 million km (142 million miles) • Temperature: varies. 2 polar ice caps • Length of 1 day: 24 Earth hours • Length of 1 year: 687 Earth days (app. 2 Earth years) • # of moons: 2
Outer Planets • Farthest from the sun • Much larger • Consist mainly of gases • Jupiter • Saturn • Uranus • Neptune
