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 is an extremely hot [WC] Wolf-Rayet type star. Its temperature is 126,000 K.[5] 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.[5]
