EQ: What is common between the inner planets?
Inner Planets
Inner Planets called Rocky planets
or terrestrial planets
1.Mercury
Smallest Planet and closest to the sun
Mercury moves very slowly
No Moons
Rotation-spin on its axis 59 days
Revolution- orbit around the
Sun - year is equal to 88 Earth
days
23
2. Venus
-Virtually the same size, mass and
Density as Earth
-Sun rises in the west and sets in the
East because it rotates opposite to
Earth
-One day on Venus is about as long as
a year on Earth
-Hottest surface because the
atmosphere is a thick cloud of CO2
(464° C).
-Rains sulfuric acid
-No oceans, Active volcanoes
-No Moons
-Typically the brightest object in the
27
sky.
Standard: 4
Astronomy
3. Earth
Just the right distance from the sun
Temperatures are right to not
completely freeze or boil away the
water
28
4. Mars
Last Inner planet
Thin atmosphere and further from the
sun so it is a cold planet
Water is in solid form-ice
Largest volcanoes
2 moons
Rotation is 24 hours and 37 minutes –
Similar to the Earth.
Revolution takes 1 year, 322 days
