Betelgeuse red supergiant star, animation

Videonummer 11944953
Betelgeuse red supergiant star. Animation of the location in the night sky and the properties of the M-type star Betelgeuse (Alpha Orionis), 643 light years from Earth in the constellation of Orion. Betelgeuse is a red supergiant star, 1180 times the width of the Sun (over 1.6 billion kilometres across) and 12 times the Sun's mass. Less than 10 million years old, Betelgeuse has evolved rapidly because of its high mass. It is in a late stage of stellar evolution, expected to explode as a type II supernova within the next million years. Betelgeuse is spectral type M2, with a luminosity class of Iab. It has a luminosity 90, 000 to 150, 000 times that of the Sun, and has an atmospheric temperature of 3140 to 3640 Kelvin. Its spectrum has strong titanium oxide lines and some calcium lines.
