NGC 2340

NGC 2340 is a large elliptical galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,008±9 km/s, which corresponds to a Hubble distance of 289.0 ± 20.3 Mly (88.61 ± 6.21 Mpc).^[1] However, six non-redshift measurements give a farther mean distance of 315.77 ± 44.34 Mly (96.817 ± 13.596 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 9 February 1788.^[3]

Close

NGC 2340 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.^[4][5]
