| So, I was browsing a random galaxy in SpaceEngine, and I ran into this...
It's tidally locked to a T8 brown dwarf, which is a tiny "star" and generates very little heat. The star itself is only 800 K / 527 C.
And yet....
It itself is 2818 K / 2545 C!!! It's 20 times brighter than it's "star!"
Could it just be really young?
Nope, it's 4.8 billion years old.
Greenhouse effect?
Nope, it's got 0.01 Atmospheres and no Greenhouse effect.
Tidal heating?
Maybe, but one has to wonder whether this is realistic. I can't see how we'd get 700 Exawatts of heat out of a tidal interaction. Can that actually happen?

| I think a tidally locked planet would have to have an orbit extremely close to its star and very eccentric for tidal heating to become a big factor, but in this case the temperature doesn't sound possible by any (realistic) mechanism.

| I've said this before, But it could be a recent impact. Does the world show signs of this? rapid rotation or an overly large crater? I don't space engine calculates these but it would really cool if it did. *cough* *cough*

| This is definately a bug. If you look around L-type dwarfs, all their planets are cool, cold or frozen. T-dwarfs are even colder, yet every planet I saw was hot or scorched, like if I went to a blue giant. Some of them were even evaporating (!?)
Careful. The PLATT Collective has spurs.

| I thought blue giants could have evaporating planets, their heat output supports it. How those planets formed (if at all) is a mystery though.
EDIT: I found another one, However the inner planets make sense. They are too close for that gravity not to have an effect on them, The outer planets maybe not so much, The outer "Warm planet" has life though being in complete darkness you have to wonder what it would look like. The inner planets are also evaporating, with negligible solar output I though if anything the clouds would be moving towards the brown dwarf creating a kind of accretion disk.
I have named the star "Dothtaal Ioth" and I have the SDD.

| Quote Pds314 (  ) Tidal heating?
This is a bug in the tidal heating calculation, it should be fixed in the next version.

| Well, it's tidally locked and it's old. So it's been earning heat over time? Is it close to its star tough?

| SpaceHopperYes i know i found a T9-dwarf system all planets are heating than star
The Planet is 1298 °C
The Star is 447 °C
Here code: RS 8409-1792-8-9782492-26 B

| Folks, it is not necessary to point out further examples of this bug. It is already known, and has already been fixed for the next release.
Quote SpaceHopper ( ) How do you know about this?
Because SpaceEngineer said so himself. You can also check the troubleshooting and bug reports thread.

| Damn, I hoped this was an actual thing. I like finding unusual things in SE and trying to figure out and develop an explanation for them.

| Just found a 2848 Celcius gas giant orbiting another superheated gas giant. Yay for tidal effects capable of melting refractory ceramics...
