Planet Name Surface & Atmosphere Temp. Day Length Year Length Size Moons Interesting facts Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto

The Inner Planets! Mercury Venus Earth Mars

Mercury! Has a surface much like our moon: cratered, but with HUGE volcanoes -Almost no atmosphere left, mostly sodium -Most extreme temperatures in solar system: 430 C during day, -170 C at night

1 day (rotation) = 59 Earth days 1 year (revolution) = 88 days 4,878 km. diameter interesting fact: we have only seen 40% of the surface, from 1 exploration: Mariner 10 It is too close to the sun to see with a telescope!

Venus! THICK atmosphere, no sun gets through. -mostly Carbon Dioxide, Nitrogen. Sulfuric acid clouds! GREENHOUSE EFFECT makes it the hottest planet! 460 C

Beneath the thick clouds is the surface: some craters, rolling hills, some volcanoes -1 day = 243 Earth days - 1 year = 225 Earth days 12,104 km. diameter no moons! interesting fact: Venus rotates in reverse (east to west) It is guessed is that something large struck it and sent it spinning the other way.

Earth! -Atmosphere is Nitrogen, Oxygen -Surface is rock, metal, water -12,756 diameter -1 year = 365 Earth days -Temperature -50 C to 60 C -1 Moon: Luna Interesting fact: Earth is thought to be the only planet with water (and life)!

Mars! Very little atmosphere, can’t hold water in. CO2, trace oxygen Poles are frozen CO2 -Temperature: -80 C to 3 C, windy - 1day= 1 day -1 year = 687 days

- Surface is red, dusty. Made of iron oxide (rust). -Volcanoes, canyons, canals carved by rivers of liquid nitrogen. Some craters -6,794 km. diameter (half of Earth!)

-2 moons: Phobos (fear) and Deimos (panic), potato shaped, small interesting fact: the 2 Mars Rovers haven’t found any traces of life even at the microscopic bacterial level! And Mars has the largest volcano in the solar system, called Olympus Mons!
