MercuryMercury has virtually no atmosphere. It however

has small traces of an atmosphere .It takes less than 88 Earth days for Mercury to

orbit around the sun which is it’s year.Because of a lack of an atmosphere, the

temperature rises above 800°F while on the dark side it falls rapidly to -300°F.

Mercury rotates slowly on its axis. It completes one rotation every 59 Earth days which is it’s day.

The surface of Mercury is heavily cratered, looking much like our moon.

Mercury does not have a natural satellite (a moon)

VenusIts atmosphere is made up mostly of carbon

dioxide which causes a run away greenhouse effect and the planet is around 900 degrees F. It is the hottest planet.

It takes 243 days to make a rotation and it takes 224 days to orbit around the sun. This makes it’s day longer than it’s year

The planet rotates from East to West which is called retrograde rotation.

Venus does not have a natural satellite (a moon)

EarthIt is made up of approx. 70% waterOnly planet known to contain lifeThe densest planetDay = 24 hours Year = 365.25 days

MarsIt is red because there is a lot of iron in the

soilMars year= 687 Earth days.Nighttime temperatures on Mars can drop as

low as -191°F.The thin atmosphere is made of mostly

carbon dioxide.Mars has seasons like Earth.Mars has two moons

JupiterIt rotates faster than any planet making the

days only 10 hours long.It is the largest planet.It has a ringThe great red spot is a storm that has been

going on for over 300 years.

SaturnIt has the lowest density of all the planets.It has over 30 known satellitesIt’s rings are made up of pieces of rocks and

dust.

UranusIt is the coldest planetIt is tilted completely on it’s side because of

impact from an asteroid It is the blue-green because of its methane

gasIt has rings

NeptuneNeptune is the stormiest planetThe planet has a system of thin dark rings Neptune has 8 known moons
