Write the information for the inner planets on the front side, one planet in each box. Do the same for the outer planets on the back side. Illustrate each planet. Your drawings should show the relative sizes of the planets, and should be colored realistically. Refer to your textbook or another source to see what colors to use. Inner Planets Mercury smallest planet closest to Sun little atmosphere, temperature extremes heavily cratered surface Venus second closest to Sun thick atmosphere traps solar energy = greenhouse effect hottest planet – about 470 C Earth’s “sister planet” – similar size slowest rotation Earth 3rd planet from Sun protective atmosphere allows life to flourish water exists as solid, liquid, & gas Mars farthest inner planet red surface has seasons and polar ice caps might have had water shape the surface in the past The asteroid belt separates the inner and outer planets. Outer Planets (Gas Giants) Jupiter largest planet 63 moons “Great Red Spot” – giant storm on surface fastest rotation has rings Saturn several broad rings, made of ice and dust 61 moons Uranus axis makes the planet spin almost sideways has rings 27 moons blue, because of methane Neptune farthest planet coldest planet has rings 13 moons blue, because of methane and helium
