NGC 6881 is a planetary nebula located in the constellation of Cygnus. It was discovered by astronomer William Herschel in 1788. This nebula is approximately 3,000 light-years away from Earth and is known for its distinct shape and bright central star, which is a remnant of a dying star that has shed its outer layers. The nebula has a diameter of about 0.5 light-years and is expanding at a rate of roughly 20 kilometers per second. Its unique structure is characterized by a complex arrangement of gas and dust, making it an interesting object for astronomers studying stellar evolution and the life cycle of stars.
