3. 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

4. 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!

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

6. 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.

7. 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)!

8. 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

9. - 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!)

10. -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!
