Which of the following characteristics of the planet Jupiter most likely makes it impossible for life to exist?

• 1,200 times more volume than earth

• has 63 moons

• average temperature of -145 degrees Celsius

• rotational period of 10 hours

Earth and Mars are similar in their proximity to the sun.

Why is Earth capable of sustaining life while Mars is not?

• Mars is in the habitable zone, but it is a bit smaller than earth,

  making it impossible to support life.

• Mars is in the habitable zone, but made of gas instead of rock, making it impossible to support life.

• Mars is in the habitable zone, but is a bit further from the sun than earth, making it too cold to support life.

• Mars is in the habitable zone, but it is a bit further from the sun than earth, making it too hot to support life.
