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 [90] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [96] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [97]
UY Scuti is located a few degrees north of the A-type star Gamma Scuti and northeast of the Eagle Nebula. Although the star is very luminous, it is, at its brightest, only 9th magnitude as viewed from Earth, due to its distance and location in the Zone of Avoidance within the Cygnus rift .
KW Sagittarii is a red supergiant star, located approximately 2,420 parsecs (7,900 light-years) away from the Sun in the direction of the constellation Sagittarius.It is one of the largest known stars, with a diameter about 1,000 times larger than the Sun.
Within 1.3 million years it will come as close to 10 light years from Earth, [10] and will be much brighter than Sirius by that time. UY Scuti is a red supergiant and is also one of the largest stars currently known with a radius over 900 times that of the Sun. [11] RSGC1-F01 is another red supergiant whose radius is over 1,450 times that of ...
This list only concerns "living" stars – those which are still seen by Earth-based observers existing as active stars: Still engaged in interior nuclear fusion that generates heat and light. That is, the light now arriving at the Earth as images of the stars listed still shows them to internally generate new energy as of the time (in the ...
The star, called LHS 3154, is relatively close to us, about 50 light years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
Another theory associated with hypergiant stars is the potential to form a pseudo-photosphere, that is a spherical optically dense surface that is actually formed by the stellar wind rather than being the true surface of the star. Such a pseudo-photosphere would be significantly cooler than the deeper surface below the outward-moving dense wind.
The newly observed disk has a diameter of about 12,000 times the distance of the Earth to the sun, or roughly 10 times larger than the one that encircled the sun when it formed approximately 4.5 ...
