Pant

Pant (Панта): a planet endangered by a global catastrophe – an explosion of its own sun as a part of standard stellar evolution. Unfortunately, there were sentient species identical to humans on the planet and so they had to be deported from it ("Ark Project") to another one. The first choice was Ark but since the discovery of a sentient alien race there, progressors have apparently changed their mind. Discovered approx. in 2161 AD.
