New study shows closest Earth-like planet ‘stroll across park,’ possibly 13 light-years away

[longship]

1. Alpha Centauri B has an Earth-sized planet.

And it's only 4.3 LY away. Unfortunately, it's a bit too close to it's star. Not nearly Earth-like.

Most of the nearby stars are M-dwarf, so-called red dwarf stars. They are small, not as hot, but these type are over 3/4 of the stars in our galaxy. Also, every one of them that ever existed since the beginning of our galaxy is still slowly and extraordinarily efficiently burning their fuel of hydrogen. Their lives will likely be a 1,000 billion years.

That means an habitable world at a red dwarf could live far, far longer than one with a star like our Sun.
