Even if we were to find one we would still lack the ability to travel there. Even traveling to mars is a lengthy journey, just existing the solar system alone is impossible within a normal human lifetime. But we could still discover one and research it which i think is equally cool. The james webb space telescope has a special tool that checks the atmosphere of distant planets which could help them find planets that sustains life. That’s probably the only way to research planets that they deem capable of sustaining life for now atleast

In the avatar universe, the interstellar starships can reach 0.7 C / speed of light using Antimatter - Matter engines. We currently understand enough about Antimatter physics to know such engines and speeds are theoretically possible.

Therefore, the time of flight to Prox A, ~4 light years away, should roughly take ~6 years.
