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 star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume...
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.
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.
14 de feb. de 2024 · In the vast night sky, where countless stars vie for attention, one colossus reigns supreme as the largest star in the universe. Situated thousands of light-years from Earth, this celestial giant's sheer magnitude challenges our understanding of stellar physics.
23 de ago. de 2022 · The star R136a1 was initially measured at around 250 to 320 times the mass of our own Sun. The new estimate places it between 150 and 230 times the mass of the Sun. This new ballpark figure of just under 200 solar masses still makes the star a heavyweight record holder, but the downward revision of its mass could have deeper implications.
