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.

A) have occurred in the central regions of the Milky Way.
B) have occurred in distant galaxies.
C) come from the same types of close binary systems that produce X-ray bursts.
D) come from the Oort cloud surrounding the Sun.
