[[File:Uncovering the secrets of the Quintuplet Cluster.jpg|thumb|278x278px|V4650 Sagittarii is the star cut off on the far left whose diffraction spikes (blue cross shape) are visible only.]] '''V4650 Sagittarii''' is a [[luminous blue variable]] (a type of [[Hypergiant|hypergiant star]]) located in the [[Sagittarius (constellation)|Sagittarius]] constellation. It is close to the center of the [[Milky Way]], the [[galaxy]] we live in. It is possibly [[List of most luminous stars|the brightest star known]], with a luminosity nearly 8 million times that of the [[Sun]].<ref>{{Cite web|last=Mauerhan|first=Jon C.|last2=Morris|first2=Mark R.|last3=Cotera|first3=Angela S.|last4=Dong|first4=Hui|last5=Wang|first5=Q.

This means that we cannot see it with our naked eye. V4650 Sagittarii has an effective temperature of 12,000 Kelvins.<ref>{{Cite web|last=Lau|first=Ryan M.|last2=Herter|first2=Terry L.|last3=Morris|first3=Mark R.|last4=Adams|first4=Joseph D.|date=2014-03-20|title=Nature Versus Nurture: Luminous Blue Variable Nebulae in and near Massive Stellar Clusters at the Galactic Center|url=https://arxiv.org/abs/1403.5298v1|access-date=2023-12-02|website=arXiv.org|language=en}}</ref> == References == {{Reflist}}{{Sci-stub}} [[Category:Stars]] [[Category:Sagittarius (constellation)]] [[Category:Hypergiants]]
