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.
10 de jan. de 2020 · The Top 10 Stars in the Sky by Diameter. Stars are immense balls of burning plasma. Yet, aside from the Sun in our own solar system, they appear as tiny pinpoints of light in the sky. Our Sun, technically a yellow dwarf, is neither the biggest or the smallest star in the universe.
Eta Carinae is the bright spot hidden in the double-lobed dust cloud. It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades.

As an astrophotographer, I’ve always been fascinated by the sheer size and complexity of the universe. And when it comes to size, there’s nothing quite like UY Scuti, the biggest star that we know of. UY Scuti is a red supergiantstar located in the constellation Scutum and is estimated to be over 1,700 times larger than our Sun. In this article, we...
Massive Core:UY Scuti has an extremely dense core that generates enormous amounts of energy through nuclear fusion.Rapid Expansion:The energy released by the core causes the outer layers of the star to expand rapidly, creating its massive size.Short Lifespan:While UY Scuti is incredibly large, it won’t live for very long due to its high rate of energy consumption.Spectroscopy:By analyzing the light emitted by a star, we can learn about its chemical composition, temperature, and other properties.Stellar Evolution Models:Using computer models, scientists can simulate the life cycles of stars like UY Scuti and make predictions about their behavior.Telescopes:Ground-based and space-based telescopes allow astronomers to observe and study stars like UY Scuti in great detail.Heavy Elements:Massive stars like UY Scuti are responsible for producing many of the heavy elements in the universe, including gold, silver, and uranium.Supernovae:When massive stars run out of fuel, they explode in a spectacular event known as a supernova, scattering their material across the galaxy.Black Holes:Some massive stars can collapse inward and become black holes, which are among the most mysterious and powerful objects in the universe.Studying stars like UY Scuti is a challenging and rewarding task for professional astronomers. Through the use of spectroscopy, computer modeling, and telescopes, we can learn a great deal about these massive objects and gain a better understanding of the universe as a whole. The incredible scale and complexity of the universe continue to amaze me,...
“The Hertzsprung-Russell Diagram” by Edward L. Robinson – This article provides an in-depth introduction to the Hertzsprung-Russell Diagram, which is a valuable tool for understanding the properties and behavior of stars like UY Scuti. The article is published on the website of the American Association of Variable Star Observers (AAVSO). “Stellar E...
WOH G64 is the largest star known in the Large Magellanic Cloud (LMC), one of the nearest galaxies to the Milky Way. The currently accepted radius of 1,540 solar radii is on the lower end of size estimates for the star.
24 de jun. de 2023 · Stephenson 2-18 took the title of the largest star known from the previous record holders, the red supergiants WOH G64 in the constellation Dorado and UY Scuti in Scutum. WOH G64 has an estimated radius between 1,540 and 1,730 solar radii, which is considerably smaller than St2-18.
8 de mai. 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 of...
