data. ARICNS. data. Proxima Centauri is a small, low-mass star located 4.2465 light-years (1.3020 pc) away from the Sun in the southern constellation of Centaurus. Its Latin name means the 'nearest [star] of Centaurus'. It was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun. With a quiescent apparent magnitude of 11. ...
Apr 5, 2024 · Proxima Centauri is the closest star to the Sun, about 4.2 light-years away in the Alpha Centauri system. As a red dwarf star—the most common type of star—Proxima Centauri is about seven times smaller than the Sun and a little more than half as hot, at 3,100 kelvins. In fact, the tiny star is only 50 percent larger than the planet Jupiter.

The star Proxima Centauri isn’t visible to the eye. Yet it’s one of the most noted stars in the heavens. That’s because it’s part of the Alpha Centauri system, the closest star system to our sun. Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the...
In Earth’s sky, Proxima is located in the direction of our constellation Centaurusthe Centaur. That’s a southern constellation, best seen from Earth’s Southern Hemisphere. And indeed – although it can be glimpsed from very southerly latitudes in the Northern Hemisphere – many experience northern stargazers say they’ve never seen Alpha Centauri. Pro...
In 2016, the European Southern Observatory (ESO) announced the discovery of Proxima b, a planet orbiting Proxima Centauri at a distance of roughly 4.7 million miles (7.5 million km) with an orbital period of approximately 11.2 Earth days. Its estimated mass is at least 1.3 times that of the Earth. Proxima b is within the habitable zone of its star....
Astronomers saidin April 2021 that they spotted a flare – or burst of radiation – from Proxima that’s 100 times more powerful than any flare seen from our sun. They said the flare ranks as one of the most violent seen on a solitary star anywhere in the galaxy. Flares like this on Proxima could doom chances for life on its planets. Astronomer R. O. ...
Many scientists engaged in the Search for Extraterrestrial Intelligence (SETI) consider the famous Wow! signal to be the best known candidate for an alien radio signal. The 1977 Wow! signal was heard only once. It was never fully confirmed and remains unexplained to this day. But in 2020 scientists found a new possible signal, dubbed by some as Wow...
Learn about Proxima Centauri, a red dwarf star with its own planetary system, located 4.2 light-years away from our sun. Find out how to spot it in the sky, what planets orbit it, and how it affects life on its planets with frequent flares.
Nov 30, 2021 · Proxima Centauri b orbits Proxima at a distance of ~0.049AU, which distance subtends an angle of 0.038 arcseconds as observed from Terra. From the same vantage Proxima b's own angular diameter is only ~0.00007 arcseconds, and even at full phase the planet's apparent magnitude cannot appear brighter than 37th at best.
