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. Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list.
25.4 ± 0.2 [6] 1.08 ± 0.06 [6]-0.05 [4] Fourth-brightest star in the night sky, and the nearest red giant to Earth. Deneb Algedi (Delta Capricorni) 38.70 ± 0.09 [1] A7m III [7] 1.91 [8] 2 [8] 2.91 [7] The nearest white giant. Capella A 42.919 ± 0.049 [9] G8III [9] 11.98 ± 0.57 [9] 2.569 ± 0.007 [9] 0.03 [10] The nearest yellow giant ...
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
25.4 ± 0.2 [100] AD This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A ...
The ejection of the outer mass and the creation of a planetary nebula finally ends the red-giant phase of the star's evolution. [10] The red-giant phase typically lasts only around a billion years in total for a solar mass star, almost all of which is spent on the red-giant branch.

It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. It is 1,344 ± 20 light-years (412.1 ± 6.1 pc) away [3] [6] and is the closest region of massive star formation to Earth. M42 is estimated to be 25 light-years across (so its apparent size from Earth is approximately 1 degree).
A majority are significantly larger than Earth, but a few have similar masses, including planets around YZ Ceti, Gliese 367, Proxima Centauri, and Barnard's Star which may be less massive than Earth. Several confirmed exoplanets are hypothesized to be potentially habitable , with Proxima Centauri b and GJ 1002 b (15.8 ly) considered among the ...
