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.
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...
14 de feb. de 2024 · While the UY Scuti is the largest star, R136a1 is currently the heaviest star in the universe. Located in the Large Magellanic Cloud, approximately 165,000 light years from Earth, R136a1 is a member of the rare class of hyper-massive stars, weighing in at more than 170 to 230 times the mass of our sun.
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. UY Scuti’s size is due to its massive core, rapid expansion, and short lifespan.
Meet the biggest and largest stars in our Universe that are hundreds of times bigger than our own Sun. These include the biggest, UY Scuti.
10 de ene. de 2020 · VY Canis Majoris. Tim Brown/ The Image Bank/ Getty Images. This red hypergiant is among the largest known stars in our galaxy. It has an estimated radius between 1,800 and 2,100 times that of the Sun. At this size, if placed in our solar system, it would reach nearly to the orbit of Saturn.
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.
