What is the smallest known star?
red dwarf star
In 2017, an international team of astronomers announced the discovery of a so-called red dwarf star that’s so small it barely functions as a star. Code-named EBLM J0555-57Ab and lying some 600 light-years away, it’s similar in size to the planet Saturn.
Which is the smallest astronomy?
The smallest planet in our solar system is Mercury and the largest planet is Jupiter.
What is the smallest star compared to Earth?
This tiny new star, which is being called EBLM J0555-57Ab, is about 600 light-years from Earth, and has a comparable mass (85 Jupiter masses) to the estimated mass of TRAPPST-1. The new star, though, has a radius about 30 percent smaller. Like TRAPPIST-1, EBLM J0555-57Ab is likely an ultracool M-dwarf star.
Is our star small?
The Short Answer: Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
How small can a star get?
While speaking at the American Astronomical Society’s 222nd conference, Todd Henry – the Professor of Astronomy at Georgia State University – revealed that a star can be no smaller than 8.7 percent the diameter of our Sun to sustain nuclear fusion.
What is the biggest star compared to the Sun?

What was the biggest star ever discovered?
W26 is about 1,500 times wider than the sun, making it the biggest known star in the universe. The red supergiant star is nearing the end of its life and will eventually explode as a supernova, researchers said.
What is the largest star ever found?
The largest known star is VY Canis Majoris, a red hypergiant measuring between 1800 to 2100 solar radii. Its volume is almost a billion times that of the Sun, though its density is much less.
What is the largest star in our galaxy?
The largest star in our galaxy is believed to be UY Scuti. It is more than 1000 times bigger than sun.
