NGC 1762 is a spiral galaxy in the constellation of Orion. Its velocity with respect to the cosmic microwave background is 4,739±2 km/s, which corresponds to a Hubble distance of 228.0 ± 15.9 Mly (69.90 ± 4.89 Mpc).[1] However, 10 non-redshift measurements give a farther mean distance of 275.44 ± 22.19 Mly (84.450 ± 6.805 Mpc).[2] It was discovered by German-British astronomer William Herschel on 8 October 1785.[3][4]

NGC 1762 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.[5][6]

NGC 1762 group

NGC 1762 is a member the NGC 1762 group (also known as LGG 120), which contains at least 27 galaxies, including NGC 1590, NGC 1633, NGC 1642, NGC 1691, NGC 1713, NGC 1719, and IC 392.[7][8]

Supernova

One supernova has been observed in NGC 1762:

  • SN 2002cy (type unknown, mag. 16.7) was discovered by South African amateur astronomer Berto Monard (it) on 8 May 2002.[9][10]
