A new analysis of decades’ worth of observations has revealed that Uranus does indeed emit more heat than it receives from the rays of the Sun.

it’s not chemical, that much i can tell you. there was a study done in 1800 iirc where they contemplated what gives the sun its enormous power and they figured out that if the sun was a solid ball of coal burning slowly, it wouldn’t last longer than 200 years iirc, at the enormous rate of power it emits. it’s a nuclear process
these nuclear processes can be very long-running. uranium takes billions of years to decay. it’s probable that a lot of planets have uranium in their interior and that heats up the planet from the inside.
