It was discovered by Ralph Copeland on September 17, 1884.^[3] It is 4.6 ± 1.0 kiloparsec (15.0 ± 3.3 kly) distant from Earth, and is composed of a hot central post-AGB star that has 55% of the Sun's mass yet 2700 ± 850 its luminosity, with a surface temperature of 142,000 K. The planetary nebula is thought to have been expanding for between 1280 and 1600 years.^[4]
