AFGL 2591 is a young, massive star in the constellation Cygnus. It is more than 3,000 light-years from Earth, at least 10 times the size of the Sun, and over 20,000 times as bright. It is estimated to be about one million years old, about 1/5,000th of the Sun's age.
AFGL 2591 is expelling a nebula of gas and dust, a common feature in the formation of stars that are similar in size to the Sun, but less common in larger stars. Over the past 10,000 years, this process has created a nebula that is over 500 times the diameter of the Solar System.
