Hi!

 

If you are interested in exoplanets, you might want to know these little known facts about exoplanets.

  1. In our stellar neighborhood there might be around 130 potentially (p.) habitable exoplanets, 10 of them being Earth-like.
  2. The closest p. Earth-like planet is called Tau Ceti e, and it is located only 12 light years away from us.
  3. So far, we have sent a targeted radio message to 2 p. habitable exoplanets, Tau Ceti e and Luyten b. Any reply would be received as of 2037 and 2041, respectively.
  4. Amateur astronomers have discovered 2 p. habitable exoplanets: LHS-1140 b and K2-288 B b.
  5. It is possible to detect exoplanets by using a tele-photo lens with an aperture of less than 50 mm.

Hope you learnt something knew!

But if I knew it I wouldn't be learning, would I? :)

Is Proxima B not earth like? I think we all know it is the closest star system (united with alpha). Is it because Proxima is a red dwarf which somehow precludes Prox B from being considered, "Earthlike"?
