This staggering image shows how our sun - which is so big it accounts for 99.86% of the mass in the solar system - would look next to the biggest star in the universe. VY Canis Majoris is so large that it is impossible to even represent the earth in this picture as it would measure less than one thousandth of a single pixel.
Following this discovery, UY Scuti was officially named the largest known star in the galaxy, surpassing previous record holders such as Betelgeuse, VY Canis Majoris, and NML Cygni. While there are stars that are brighter and denser than UY Scuti, it has the largest overall size of any star currently known, with a radius of 1,708 Â± 192 Râ. That figure amounts to somewhere between 1,054,378,000 and 1,321,450,000 miles in size, which is about 1,700 times larger than our Sunâs radius and 21 billion times the volume.
