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

[edit]

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 [fr], NGC 1713 [fr], NGC 1719, and IC 392 [fr].[7][8]

Supernova

[edit]

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]
