NGC 4361 (also known as the Lawn Sprinkler Nebula^[4] or Garden Sprinkler Nebula) is a planetary nebula in the constellation of Corvus.^[3]^[1]^[2] It is included in the Astronomical League's Herschel 400 Observing Program.

Central star

NGC 4361's central star, which has the Henry Draper Catalogue designation HD 107969,^[5] is an extremely hot [WC] Wolf-Rayet type star. Its temperature is 126,000 K.^[6] It is nearly 18,000 times brighter than the Sun, but is only 6.1% its size. This star left the asymptotic giant branch between 5776 and 8018 years ago.^[6]
