Central star

NGC 4361's central star, which has the Henry Draper Catalogue designation HD 107969, is an extremely hot [WC] Wolf-Rayet type star. Its temperature is 126,000 K. 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 5,776 and 8,018 years ago.
