Analysis of Morrison and Cruikshank's (1974) infrared flux measurements of Uranus and Neptune shows that Uranus is probably in equilibrium with the incident solar flux, while Neptune probably radiates 2.4 times as much energy as it receives from the sun, implying an internal heat source of 1.4 times the solar input. On the basis of very broadband data (1.5 to 300 micron) Jupiter has been shown to radiate more energy than it receives from the sun. Of the Jovian planets, only Uranus, the least massive, appears to lack an internal heat source.
