NOTE—during its red giant lifetime, the sun will expand to 256 times larger than it is now. It will have a luminosity of 34,265 suns and an absolute magnitude of -6.51, apparent magnitude of -38.01, and a surface temperature of 5,000 kelvin. Sol began its life 40 million years before earth formed. It has increased its luminosity 1% every 100 

million years (30% in 4.5 billion years). In 1.1 billion years, the sun will be 10% brighter, and in 3.5 billion years, it will be 40% brighter. the helium fusing phase will last for 130 million years, and the sun will expand past the orbits of mercury and venus. in 7.59 billion years, the sun will become a red giant. Its mass will then be decreased 67% and will be 1/2 as hot as it is now. the earth will be engulfed before the red giant phase and the sun will grow .25 AU during the next 500,000 years.

Fate of the star— planetary nebula, white dwarf star 

This star system is an eclipsing binary system. The 2 stars are separated by 151.37 million miles and have a period of 759 days. The main star is 4% beyond its main sequence lifetime. An excess of infrared emissions at wavelength 60 micrometers suggests the presence of a debris disk. The heat of the debris disk is 85 degrees kelvin which corresponds to an orbital radius of 88 AU (8.184 billion miles). Our star’s copier belt has an orbit of 30-50 AU (2.79-4.65 billion miles).

Binary star system with a red giant variable, Mira a, and a white dwarf, mira b. They are separated by 70 AU (6.61 billion miles) and have a period of 585.66 years. Mira a is a pulsating variable star, the first non supernova pulsating star discovered, with the possible exception of Algol. The period between pulses is 10,000 years, and when each pulse’s luminosity increases, the pulse grows stronger. Mira shed its 13 light year long tail 10s of thousands of years ago. The star is moving 130 kilometers/second 

(80.83 miles/second). Mira b could be a k type main sequence star of mass .7 suns.

This star will evolve back to a blue supergiant star, then to a luminous blue variable or wolf rayed star before its core collapse. Its post red supergiant phase will be a type 2n/2b supernova or wolf rayed type 1b/1c supernova. It is one of the most luminous red supergiant stars in the milky way and one of the largest to be discovered. A spherical shell of ejected matter extends out to 6 arc seconds, or 1.8968 billion miles with an expansion velocity of 6.2 miles/ second, and is 2000-3000 years old. For an age of 2000-3000 years old and an expansion rate of 6.2 miles/ second, the shell would be 391.3-652.19 billion miles in diameter.
