NGC 7769 is an unbarred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 3855 ± 25 km/s, which corresponds to a Hubble distance of 56.85 ± 4 Mpc (~185 million light-years). [1] It was discovered by German-British astronomer William Herschel on 18 September 1784. [2]

2024年8月20日 · NGC 7770 shows star-forming clumps in its inner disk, in contrast to the compact nucleus of NGC 7769. And, there are numerous, and delightful, smaller galaxies throughout the frame.

2024年9月11日 · This trio of interacting galaxies is located 200 million light years away in the constellation of Pegasus at a declination of +20 degrees. As shown in the mouseover, the right large galaxy is NGC 7769, the left large galaxy is NGC 7771, and the satellite just below this galaxy is NGC 7770.

NGC 7769 is a Spiral Galaxy in the Pegasus constellation. NGC 7769 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 12.77, NGC 7769 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.

2019年12月28日 · NGC 7769 (UGC 12808, PGC 72615 and others) is a LINER-type AGN spiral to the right of center. NGC 7771 (UGC 12815, PGC 72638 and others) is the spiral to the left (east) of NGC 7769. NGC 7770 (UGC 12813, PGC 72635 and others) is the elliptical below NGC 7771. All of these are approximately 195 million light-years away in Pegasus.

An isolated group of three galaxies, NGC 7769 ( LINER, Sb, 180 Mly) is at upper left and the smaller NGC 7770 (Sa, 193 Mly) is to the right of NGC 7771 (SBa) at bottom center. PGC 214993 is just above NGC 7770. The faint galaxy just below NGC 7769 is not identified.

2024年5月25日 · Based on a recessional velocity of 4210 km/sec, NGC 7769 is about 195 million light-years away. Given that and its apparent size of 3.2 by 2.7 arcmin, it is about 180 thousand light-years across.

NGC 7769 est une galaxie spirale située dans la constellation de Pégase. Sa vitesse par rapport au fond diffus cosmologique est de 3 855 ± 25 km/s, ce qui correspond à une distance de Hubble de 56,8 ± 4,0 Mpc (∼185 millions d' al) 1.

The right large galaxy is NGC 7769, the left large galaxy is NGC 7771, and the satellite just below this galaxy is NGC 7770. The disks of each of the large galaxies span just over 1 arc-minute in our apparent view, which corresponds to a diameter of 80,000 light years.
