This extended gaseous atmosphere has been observed moving toward and away from Betelgeuse, depending on fluctuations in the photosphere. Betelgeuse is the brightest near-infrared source in the sky with a J band magnitude of −2.99; [94] only about 13% of the star's radiant energy is emitted as visible light. If human eyes were sensitive to ...
This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. ... Betelgeuse: 408 ...
If Betelgeuse were too close to Earth, the eventual supernova could cause an extinction here on Earth. However, even at 530 light-years distance, our planet will still be safe from the eventual ...
So far, 131 such objects have been found. Only 22 are bright enough to be visible without a telescope, for which the star's visible light needs to reach or exceed the dimmest brightness visible to the naked eye from Earth, 6.5 apparent magnitude. [1] The known 131 objects are bound in 94 stellar systems.
Found in the constellation Orion, Betelgeuse is extremely bright, especially considering that it’s roughly 650 light-years from Earth (though, it does have a radius 1,000 times bigger than the Sun).
The star is Betelgeuse, a red supergiant in the constellation Orion. The asteroid is Leona, a slowly rotating, oblong space rock in the main asteroid belt between Mars and Jupiter.

In late 2019 and early 2020, Betelgeuse blew its top. Literally. Around that time the famous bright star marking the right shoulder of Orion suddenly started dimming, dropping to about half its ...
