'''NGC 4845''' (also known as '''NGC 4910''') is a [[spiral galaxy]] located in the constellation [[Virgo (constellation)|Virgo]] around 65 million [[light years]] away.<ref>{{Cite web|last=Morrow|first=Ashley|date=2016-01-08|title=Hubble Sees a Supermassive and Super-hungry Galaxy|url=http://www.nasa.gov/image-feature/goddard/2016/hubble-sees-a-supermassive-and-super-hungry-galaxy|access-date=2020-08-21|website=NASA}}</ref> The galaxy was originally discovered by [[William Herschel]] in 1786.<ref>{{cite web|url=http://cseligman.com/text/atlas/ngc48.htm#4845|title=NGC Objects: NGC 4800-4849|publisher=Courtney Seligman|access-date=May 13, 2013}}</ref> It is a member of the [[NGC 4753 Group]] of galaxies, which is a member of the [[Virgo II Groups]], a series of galaxies and [[galaxy cluster]]s strung out from the southern edge of the [[Virgo Supercluster]].<ref name="atlas universe">{{cite web | title=The Virgo III Groups |work=Atlas of the Universe |url=http://www.atlasoftheuniverse.com/galgrps/viriii.html |access-date=2010-11-27 }}</ref>

The galaxy has a [[supermassive black hole]], called IGR J12580+0134, at its center with a [[Solar mass|mass]] of 300,000<math>\begin{smallmatrix}M_\odot\end{smallmatrix}</math>. In 2013, the [[European Space Agency|ESA]] observed the black hole absorbing matter from a nearby, low-mass object; possibly a [[brown dwarf]] star.<ref>{{cite web|url=http://news.nationalpost.com/2013/04/04/astronomers-watch-as-supermassive-black-hole-wakes-up-swallows-planet-whole/|title=Astronomers watch as supermassive black hole 'wakes up,' swallows planet whole|publisher=[[National Post]]|date=April 4, 2013|access-date=May 13, 2013}}</ref><ref>{{Cite journal |last1=Lei |first1=Wei-Hua |last2=Yuan |first2=Qiang |last3=Zhang |first3=Bing |last4=Wang |first4=Daniel |date=2016-01-01 |title=Igr J12580+0134: The First Tidal Disruption Event with an Off-Beam Relativistic Jet |journal=The Astrophysical Journal |volume=816 |issue=1 |pages=20 |doi=10.3847/0004-637X/816/1/20 |doi-access=free |issn=0004-637X|arxiv=1511.01206 }}</ref> The observed X-ray flare was caught by the ESA's [[INTEGRAL]] telescope.<ref>{{cite web|url=http://www.geekosystem.com/ngc-4845-black-hole-eats-planet/|title=Watch a Black Hole Feed on Its Planet-Sized Prey |author=Jeff LaSala|publisher=Geekosystem|date=April 3, 2013|access-date=May 13, 2013}}</ref>
