All four of the sun’s giant planets emit more energy than they receive from the sun.
Like the sun’s other giant worlds, Uranus (seen in this 1986 photo from the Voyager 2 spacecraft) radiates more energy than the sun gives it, though not nearly as strongly as its massive peers do.

Uranus emits more energy than it gets from the sun, two new studies report — a discovery that contradicts findings from the venerable Voyager spacecraft.
When Voyager 2 sped past Uranus on January 24, 1986, the spacecraft detected no significant excess heat from the planet, making it seemingly unique among the sun’s giant worlds. However, new observations from space- and ground-based telescopes reveal that Uranus does in fact radiate more energy than sunlight provides, two research teams report in work submitted to arXiv.org in late February.
“Uranus is not as odd as we thought it was,” says planetary scientist Patrick Irwin of the University of Oxford, a coauthor on one of the studies.
Both teams say that Uranus, which takes 84 years to orbit the sun, reflects a bit more sunlight into space than Voyager had found. This means that the sun heats the planet less than previously thought, suggesting that Uranus must generate some heat to explain its temperature.
The upshot: “Uranus does indeed have internal heat,” says Liming Li, a planetary scientist at the University of Houston and coauthor on the other study. This heat is presumably left over from the planet’s birth.

Yeah. No.
Especially after Mexican food
The comments on this one should be good.
Is that AOC?
Freddie Mercury could run his Stanley Steamer car with the heat he produced.
Probably not.
Perhaps the name should be changed to “Swampanus”?
This thread is doomed.
Cue Beavis and Butthead…
Maybe....but here in Upstate...that seat still feels like sitting on an ice cube.
Photoshopped. W on the TV screen.
I couldn’t pass this one up
I was wondering about that.
Oh boi. Here we go! Lol
That should be very obvious with common sense. Much smaller earth still has more molten lava inside than cooled crust outside after 5 Billion years.
Bigger Uranus will retain its molten core longer than earth.
