'''NGC 5777''' is a large [[Spiral galaxy|edge-on spiral galaxy]] located in the [[Draco (constellation)|constellation Draco]].<ref>{{Cite web |title=NGC 5777 - Spiral Galaxy in Draco {{!}} TheSkyLive.com |url=https://theskylive.com/sky/deepsky/ngc5777-object |access-date=2024-04-16 |website=theskylive.com}}</ref> Its speed relative to the cosmic microwave background is 2,210 ± 5&nbsp;km/s, which corresponds to a Hubble distance of 32.6 ± 2.3 Mpc (~106 million ly). NGC 5777 was discovered by German-British [[astronomer]] [[William Herschel]] in 1789.<ref>{{Cite news |title=NGC 5777 Galaxy Facts (UGC 9568) & Distance |url=https://www.universeguide.com/galaxy/ngc5777 |access-date=April 16, 2024 |website=Universe Guide |date=2 July 2022 |language=en-us |last1=Guide |first1=Universe }}</ref>

The luminosity class of NGC 5777 is II and it has a broad HI line.{{clarify|date=April 2024}} It is also an [[Active galactic nucleus|active galaxy]] with [[Spectral line|narrow optical emission lines]].<ref>{{Cite web |first=Salvatore |last=Iovene |title=NGC 5777 |url=https://www.astrobin.com/110741/ |access-date=2024-04-16 |website=AstroBin |language=en}}</ref>{{fv|date=April 2024}} To date, nine non-redshift measurements yield a distance of 44.289 ± 8.577 Mpc (~144 million ly), which is just within the distance values of Hubble.

A spectrum obtained on July 10, 2001, by the [[Isaac Newton Telescope]] showed a type-IIp supernova at the center of NGC 5777.<ref>{{Cite journal |last1=Hurst |first1=G.
