What are the largest types of stars?
A supergiant is the largest known type of star; some are almost as large as our entire solar system. Betelgeuse and Rigel are supergiants.
Which is biggest sun or star?
On a stellar scale, it’s really quite average — about half of the known stars are larger; half are smaller. The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What is the biggest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
Which is the hottest star in the universe?
But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.
What is the smallest star in the universe?
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.
How many Earths can fit in the biggest star?

Is Star bigger than the Earth?
Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn’t even a particularly large star.
What is the hottest star color?
White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped.
What is the name of the coolest star?
One way that stars are categorized is by temperature. Since the temperature of a star can determine its visual color, this category scheme is known as spectral type. The main categories of spectral type are M, K, G, F, A, B, and O. The coolest stars (red dwarfs) being M, and the hottest stars being O.
Is our sun a red dwarf?
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. … The sun will puff up into a red giant and expand past the orbit of the inner planets, including Earth.
