The 10 Biggest Stars In The Milky Way

The universe is enormous, and I mean enormous. There are many fascinating objects to uncover, such as planets, galaxies, and one of the most fascinating objects, stars, stars. Stars are massive, and they are the central focus of every solar system. In this article, we will list the 10 Biggest Stars in the Milky Way.

What is the solar radius?


Before we begin with the list, we must first understand the concept of the solar radius.

A solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.

1 Solar Radius = 1 SUN



Biggest Stars In The Milky Way

Stephenson 2-18

stephenson 2 18 02 - The 10 Biggest Stars In The Milky Way

Stephenson 2-18 is Red hypergiant star located in the constellation of Scutum It lies near the open cluster Stephenson 2, which is located about  20,000 ly away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy.
Solar Radius: 2,150

UY Scuti


UY Scuti is a red supergiant star in the constellation Scutum. It is considered one of the largest known stars by radius and is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56. 

It has an estimated radius of 1,708 solar radii, thus a volume nearly 5 billion times that of the Sun. It is approximately 9,500 light-years from Earth.

Solar Radius: 1,708

RSGC1-F01

RSGC1-F01 is a red supergiant located in the RSGC1 open cluster in the constellation of Scutum. 

The radius was calculated to be around 1,530 times that of the Sun, making it one of the largest stars discovered so far. 

This corresponds to a volume 3.58 billion times bigger than the Sun. If placed at the center of the Solar System, the photosphere would submerge the orbit of Jupiter.

Solar Radius: 1,530

VY Canis Majoris

VY Canis Major is a red hypergiant and pulsating variable star 3,900 light-years from the solar system in the slightly southern constellation of Canis Major. 

It is one of the largest known stars, is one of the most luminous and massive red supergiants, as well as one of the most luminous stars in the Milky Way.

Solar Radius: 1,420

AH Scorpii

S Persei is a red supergiant located near the Double Cluster in Perseus, north of the cluster NGC 869. 

It is a member of the Perseus OB1 association and one of the largest known stars. If placed in our solar system, its photosphere would engulf the orbit of Jupiter.

Solar Radius: 1,364

VX Sagittarii
