24 de jun. de 2023 · Stephenson 2-18 (St2-18) is a red supergiant or red hypergiant star located in the constellation Scutum. Also catalogued as Stephenson 2-DFK 1 and RSGC2-18, it is the current record holder for the largest star known, with a size 2,150 times that of the Sun. The star is located at a distance of 18,900 light years from Earth.
8 de may. de 2023 · The biggest known star is UY Scuti, about 1,700 times larger than the sun. (Image credit: Philip Park (CC BY-SA 3.0)) However, all stellar sizes are estimates. "The complication with stars is...
Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi ). [1] The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars.
Stephenson 2-18 (Stephenson 2 DFK 1) is currently the largest star known. The red supergiant or hypergiant star has an estimated radius 2,150 times that of the Sun. However, the value is highly uncertain because it is significantly larger than stellar evolution theory predicts. The upper limit on stellar size is around 1,500 solar radii.
Since massive stars are rare, astronomers must look very far from Earth to find them. All the listed stars are many thousands of light years away, which makes measurements difficult.
The biggest star in the universe is UY Scuti, a red supergiant star that is estimated to be over 1,700 times larger than our Sun. It is located in the constellation Scutum and has a diameter of approximately 2.4 billion kilometers.
