What is the biggest star in solar system

What are the largest stars in the world?

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). The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars.

What is the biggest star in the universe?

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.

Which star has the largest radius?

The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars. (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris) Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red novae.

Which star is bigger than the Sun?

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 that they have diffuse edges," astronomer Jillian Scudder of the University of Sussex wrote for The Conversation.

What is the most massive star in the sky?

At the top end of the scale, the most massive known star in the sky is R136a1, a star more than 300 times as massive as our sun. And it's not alone in dwarfing Earth's dominant star. RMC 136a1, usually abbreviated as R136a1, lies about 163,000 light-years from Earth in the Tarantula Nebula.

What is the brightest star in the universe?

The title of the brightest star in the universe, in terms of intrinsic luminosity, belongs to the luminous blue variable star Eta Carinae. Situated approximately 7,500 light-years from Earth, in the constellation Carina, Eta Carinae outshines our own sun millions of times over.
