NGC 2415

Galaxy in the constellation Lynx From Wikipedia, the free encyclopedia

NGC 2415 is an irregular galaxy in the constellation of Lynx,[1] near the border with Gemini (some sources claim it is in Gemini[3]). Its velocity with respect to the cosmic microwave background is 3,935±12 km/s, which corresponds to a Hubble distance of 189.3 ± 13.3 Mly (58.04 ± 4.07 Mpc).[2] It was discovered by German-British astronomer William Herschel on 10 March 1790.[4][3]
