I get really excited over exoplanets that are Earth-like so I’m wondering how this works.
In: Planetary Science
There are some stars that have been detected that are so far away that they will have died billions of years ago.
Known exoplanets on the other hand are around stars that are much closer. If an exoplanet is detected around a star that is a few thousand light years away then they are almost certainly still around. Thousands of years isn’t very long in the lifetime of stars so odds are that those stars and their exoplanets are alive and doing fine.
