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.
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.
UY Scuti is the largest star in the Universe observed so far. The red supergiant is 1,708 times wider than our Sun, with a radius of 1.2 billion km (738 million miles). The star can be found around 9,500 light-years away from Earth in the Scutum Constellation, around the centre of the Milky Way.
10 Ιαν 2020 · Updated on January 10, 2020. 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.
Left to right: a red dwarf, the Sun, a B-type main sequence star, and R136a1. At around 4,677,000 L☉, R136a1 is one of the most luminous stars known, radiating more energy in four seconds than the Sun does in a year. From 2010 to 2020 it was recognized as the most massive and luminous star known. [25]
14 Φεβ 2024 · UY Scuti holds the prestigious title of the largest known star, a red supergiant star that dwarfs even the most luminous stars in our night sky. As a hypergiant star, UY Scuti's immense size is almost incomprehensible, with a radius about 1,700 times larger than that of our Sun.
