The red-giant branch variable star Gamma Crucis is the nearest M-class giant star at 88 light-years. [25] The K1.5 red-giant branch star Arcturus is 36 light-years away. [ 26 ]
UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum.It is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
Mira was historically thought to be a red supergiant star, but is now widely accepted to be an asymptotic giant branch star. [32] Some red supergiants are larger and more luminous, with radii exceeding over a thousand times that of the Sun. These are hence also referred to as red hypergiants: Mu Cephei; VV Cephei A; NML Cygni; S Persei; UY Scuti
The images show the surface of the star R. Doradus, a red giant star 180 light-years away in the Dorado constellation. The star has a diameter about 350 times that of the sun, and it serves as a ...
New examinations of this behemoth star suggest it is both smaller — and closer — than astronomers believed. This red giant star will, one day, explode as a supernova. However, it is ...
VY Canis Majoris (abbreviated to VY CMa) is an extreme oxygen-rich red hypergiant or red supergiant (O-rich RHG or RSG) and pulsating variable star 1.2 kiloparsecs (3,900 light-years) from the Solar System in the slightly southern constellation of Canis Major.
The red giant π1 Gruis is 530 light-years away, and it's reaching the end of its natural life. Soon, scientists think it will become a planetary nebula. But before it dies, astronomers are using ...
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 [91] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [97] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [98]
