Recently a new star has
been discovered. The HR 5171 is a yellow hypergiant 13000 times larger than our
sun, and is considered as one of the largest stars found, and probably the largest one in the Milky Way. Also, scientists
have found that HR 5171 is a part of a binary and its partner star is “ so close that they touch and the whole system resembles a
gigantic peanut” as said by Côte d’Azur Observatory’s Olivier Chesneau.
A hypergiant is basically a
supergiant – the largest stars that ranges between 10-70 solar masses [1 solar
mass =1.9891 × 1030 kilograms
= simply the mass of the sun]. They are also tens of thousands to hundreds of
thousands brighter than the sun. Though, some will be hundreds of times as
massive with very high levels of luminosity which makes them a hypergiant.
Other supergiants found
in our galaxy are the KW Sagitarii and KY Cygnii among others.
