Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations. Indeed, most of the humans involved would never see Earth or its exoplanet counterpart.

How long will Alpha Centauri live?

so for Alp-Cen A you get 7.2×109 or about 1.7 billion years left. For Alp-Cen-B you get 1.8×1010 or about 12 billion years left. The Red Giant phase will then last about a billion years.

Is there a planet with 4 suns?

The planet is named Tatooine. In another classic case of science fiction turning into science fact, astronomers found a planet circling not two, but four stars. The most amazing aspect of this find? The planet was discovered by two “armchair” astronomers!

How long is a day on Alpha Centauri B?

Alpha Centauri Cb Despite the fact that it orbits 20 times closer to the star than Earth is to the Sun, the planet is in the habitable zone, though it is tidally locked, meaning its rotation and orbital periods are identical at 11.186 days or 268.5 hours.

How much bigger is Proxima Centauri B?

Proxima Centauri b orbits the star at a distance of roughly 0.05 AU (7.5 million km) with an orbital period of approximately 11.2 Earth days. Its estimated mass is at least 1.07 times that of Earth.
