How far is the nearest habitable planet?

The nearest such planet was then as close as 12 light-years away but (see below) is now estimated slightly above four light-years away. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth (not counting the Sun).

Is there a star brighter than the sun?

While Deneb shines the brightest in the constellation Cygnus, 17 other stars glow brighter in our night skies. But Deneb is much farther from Earth than most of the other stars you see, and this giant is around 100,000 times brighter than the Sun.

Is Sun the nearest star to Earth?

The simple answer is that the Sun is the closest star to Earth, about 93 million miles away. But that might not answer your question. Outside of our Sun, our system’s nearest neighbor is Alpha Centauri. This isn’t a single star, it’s actually a triple-star system — three stars bound together by gravity.

What is the nearest planet that can support life?

Proxima Centauri b (also called Proxima b or Alpha Centauri Cb) is an exoplanet orbiting in the habitable zone of the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of a triple star system.
