How does the heat Jupiter radiates compare to the energy it receives from the Sun?
A)They are equal, as you would expect for a highly reflective planet.
B)Jupiter's dark belts absorb most of the solar radiation, so it is cooler in the infrared.
C)Jupiter radiates back into space about twice the energy it gets from the Sun.
D)Jupiter is a brown dwarf, about a hundred times less luminous than the Sun.
E)Jupiter is a red dwarf, about a tenth the Sun's luminosity.

Question

Quizplus · Accepted Answer

Jupiter radiates back into space about twice the energy it gets from the Sun, indicating that it has an internal heat source. It is not highly reflective (A), nor does it have dark belts that significantly absorb solar radiation (B). Jupiter is not a brown dwarf (D) or a red dwarf (E), as it is a gas giant planet. Jupiter radiates back into space about twice the energy it gets from the Sun, due to internal heat generated by gravitational contraction.
