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.
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 ...
With a radius between 640 and 764 times that of the Sun, [14] [11] if it were at the center of our Solar System, its surface would lie beyond the asteroid belt and it would engulf the orbits of Mercury, Venus, Earth, and Mars. Calculations of Betelgeuse's mass range from slightly under ten to a little over twenty times that of the Sun.
The nearest white giant. Capella A 42.919 ± 0.049 [9] G8III [9] 11.98 ± 0.57 [9] 2.5687 [9] 0.03 [10] The nearest yellow giant, together with Capella A. With a magnitude of 0.08, [11] the Capella star system is the 6th-brightest star in the night sky. Capella B G0III [9] 8.83 ± 0.33 [9] 2.48 [9] 0.16 [10] The nearest yellow giant, together ...
One region contained larger and more luminous stars of spectral types A to M and received the name giant. [1] Subsequently, as they lacked any measurable parallax, it became apparent that some of these stars were significantly larger and more luminous than the bulk, and the term super-giant arose, quickly adopted as supergiant.

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 [93] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [99] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [100]
The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away. Both stars belong to the Milky Way galaxy.
The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
