WASP-12b will turn into a Chthonian planet in millions of years... Makes you appreciate Saturn for saving Jupiter from falling into The Sun and ending up like WASP-12b. Jupiter got lucky that there was a planet to save it, but WASP-12b and many other Hot-Jupiters like it became unlucky.
Fun fact: Our Jupiter almost becoming a hot Jupiter kinda formed the inner planets - while in the inner Solar system, Jupiter concentrated the disk material enough for them to accrete into the rocky planets we know today.
This is all due to planetary migration. When stars form a disc of gas forms and a gas planet forms and due to interactions with the disc it falls into a lower orbit.Many planetary systems also wont be habitable because of this.
this is also what happened to most hot Neptune's these planets are very rare because they orbit so close to their star and is too small to survive longer than a million years
2m km left 0:46 mass 400x earth 1:12 1m km 1:35 2.5m years 1:44 - 1:45 500k km 1:55 - 1:56 250k km 2:02 - 2:03 200x earth mass 2:04 2:06 100k km 2:07 50k km left also bye bye wasp 12 b
