2. National Aeronautics and Space Administration Earth’s Energy Budget 2 Mars Venus Earth Mercury Our Natural Place … in the Big Picture Not to Scale

3. National Aeronautics and Space Administration Earth’s Energy Budget 3 Mars T s = -113 to 0 C Venus T s =450 C! Earth Mercury: T s =425 C Our Natural Place … in the Big Picture 425 C ~ 800 F “Too hot!” “Too cold!”

4. National Aeronautics and Space Administration Earth’s Energy Budget 4 Mars T s = -113 to 0 C Venus T s =450 C! Earth: T s = -18 C* Mercury: T s =425 C Our Natural Place … in the Big Picture 425 C ~ 800 F *No atmosphere

5. National Aeronautics and Space Administration Earth’s Energy Budget 5 Mars T s = -113 to 0 C Venus T s =450 C! Earth: T s = 15 C* Mercury: T s =425 C Our Natural Place … for Life 425 C ~ 800 F *With atmosphere “Just right”
