Rigel

Rigel is a hot supergiant star in the Milky Way galaxy. It is a blue-white supergiant. It is in the constellation Orion.

Rigel is much larger than our Sun. It is 78 times the Sun's radius, with a diameter of more than 100 million kilometers, but it's mass is 21 times more massive than our sun. It's a temperature of 12100 Kelvin, which causes the star to glow about 120 000 times brighter than the Sun. ^[1]Rigel is 864 light-years (8.2 quadrillion km) from Earth in Orion. Because it is near the equator, Rigel is seen from Earth as a small, bluish circle on clear nights from both hemispheres.
