DESCRIPTION
-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! Mercury

Mercury
Venus
Earth
Mars
Mercury-has a surface much likeour moon: cratered, but with HUGE volcanoes
-no atmosphere
-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!
Mercury
Venus-THICK atmosphere
-mostly Carbon Dioxide
-sulfuric acid clouds
-GREENHOUSE EFFECT makes itthe hottest planet at 460ºC
“Morning Star”
Beneath the thick clouds is the surface:
-some craters, rolling hills, and 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.
Venus
Earth-Atmosphere isNitrogen, Oxygen-Surface is rock, metal,water-12,756 diameter-1 year = 365 Earth days-Temperature -50ºC to 60ºC-1 Moon: Luna
Interesting Fact: Earth is thought to be theonly planet with water and life!
Mars-Very thin atmosphere: CO2, trace oxygen
-Poles are frozen CO2
-Temperature: -80ºC to 3ºC
-1day= 1.03 days(~ 24 ½ hours)
-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!)
Mars
-2 moons: Phobos (fear) and Deimos (panic), potato shaped, small
Interesting Fact: the 2 MarsRovers haven’t found anytraces of life even at the microscopic bacterial level! Mars
