What type of star is Alnitak?
Alnitak is a very interesting star, because it is not one, but three stars. The main star, Alnitak Aa, is a type 09.5 blue supergiant that is orbited at 11 Astronomical Units (roughly the distance at which Saturn orbits the Sun) by a type O blue dwarf that astronomers call Alnitak Ab. This binary star system is orbited at 680 AUs (roughly the distance of the inner Ort Cloud from the Sun) by the bluish-white type B0 Alnitak B.
How far from earth is the star Alnitak?
Approximately 700 light-years.
What is the size of alnitak star?
Alnitak, also known as Zeta Orionis, is a massive blue supergiant star located in the Orion constellation. It has an estimated radius about 20 times greater than that of the Sun and is approximately 100,000 times more luminous. Alnitak is part of a triple star system, with its two companion stars being less massive but still significant in size. Its immense size and brightness make it one of the prominent stars in the night sky.

What type of stars is our sun and where is it in its life cycle?
Our Sun is a G2V class star, and is about half-way through its expected life. In about 4 billion years or so, the Sun will begin to die, and will expand into a red giant star, which will probably destroy Mercury and Venus, and possible Earth and Mars as well. After a few hundred million years, the Sun will begin to fall in on itself, and will contract to a white dwarf star and over the next several billion years will probably further decay into a red dwarf.
