(Though not definitely.) Also because of Proxima b’s proximity to its star, it is likely to be in a tidally locked orbit — which would mean, as in the Moon’s orbit of Earth, that one side ...

An Earth-sized planet located just 4.25 light-years away in orbit around the star Proxima Centauri. The planet is called "Proxima b" and it will undoubtedly be a leading target for scientists as ...

Alpha Centauri A and B orbit each other at a distance like the Sun and Uranus, while Proxima Centauri is very much on the outer, roughly 10,000 times as far from the pair as Earth is from the Sun.

Plus, Proxima b is far from being a twin of our planet ... two things that it would need to sustain habitability in orbit around its active, flaring star. We simply don't know if it can support ...

but declaring Proxima-b to be habitable has given scientists pause. The exoplanet is incredibly close to its star, completing an orbit in just over 11 Earth days (compared to our own 365-day year).

Planets that orbit around other stars are called exoplanets ... along with other previous discoveries such as Proxima b and d, shows that our cosmic backyard is full of low-mass planets.’ ...
