NGC 2415

NGC 2415 is an irregular galaxy in the constellation of Gemini. 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).^[1] It was discovered by German-British astronomer William Herschel on 10 March 1790.^[2][3]
