• Temperature and Formation of our Solar System

2
When the solar system formed, what was the
temperature at the location of Earth?

• -100 Fahrenheit
• -100 Kelvin
• -73 Celsius
• 199 Kelvin
• 212 Fahrenheit
• 600 Kelvin
• 600 Celsius
• 1.0 AU

3
Which planets formed at temperatures hotter than
the freezing point of water?

• Mercury
• Venus
• Earth
• Mars
• Jupiter
• Saturn
• 1-4 above
• 1-5 above
• All of the above

4
At temperatures hotter than the freezing point of
water, hydrogen helium have too much energy to
condense and form Jovian planets. How close to
the Sun could a Jovian planet have formed?

• As close as Earth
• As close as 2 AU
• As close as 4 AU
• As close as Jupiter
• As close as Saturn
• None of the above

5
Around some other stars just like the Sun, we see
Jovian planets closer to their host stars than 2
AU. We just said that was impossible, so

• Something must be wrong with our idea of where
  Jovian planets can form.
• Those close-in Jovian planets might have formed
  farther out, then migrated inward to their
  current locations.
