“Did Scientists Just Discover the Best Ever Super Earth?” Because it is easy to observe, not because it is habitable

Exoplanet Comparison Gliese 581 d

 

“Did Scientists Just Discover the Best Ever Super Earth?” from Unveiled, April 12, 2021

The planet in question is Gliese 486b, around a red dwarf 26 light years away.  It has 10 times Earth’s mass and is thought to be a hot, volcanic planet like Venus. It transits its star frequently in a manner that makes it very easy for astronomers to study it.

Gliese 581c is around an even nearer red dwarf star, 20 light years away, 5 times Earth’s mass, gets discusses.  Space.com thinks it might be too hot.

A better chance is 581d, or even 581g, if it exists.
