What is the rarest star in the universe?
A strange star has been identified that might be one of the rarest things ever, with perhaps as few as five or six of them in the galaxy. J005311 is a bizarre star located in the constellation Cassiopeia about 10,000 light-years from Earth.

What is the least common type of star?
The average lifespan of a star ranges from 10 million years for the blue giants to 100 billion years for the red dwarves. Red dwarfs are the most widespread kind of star (lower right), whereas blue giants are the rarest (upper left).
What is the most common star type?
Individual red dwarfs, on the other hand, are by far the most prevalent kind of star in the Milky Way. They are nevertheless quite difficult to spot since they have such a low luminosity.
What is the most beautiful star?
Sirius, or the Dog Star, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, since only a few planets (the entire moon and the International Space Station), as well as n just one other star, outshine this heavenly body.
What is the hardest thing in the universe?
Scientists have determined the material’s strength deep within a neutron star’s crust and discovered it to be the universe’s most powerful substance.
What color is the coolest star?
The color of a star reveals a lot about it. You may determine the star’s temperature. The coldest stars are red. Hotter than red stars are yellow stars.
Which star is coldest?
Star name | Temperature (K) | Distance (light years)
- WISE J0855-0714 225–260 7.27±0.13
- CFBDSIR 1458+10B 370 104
- 2MASS 0939-2448 A/B 650 17.4±0.4

What is the biggest star?
UY Scuti – the biggest star
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in its greatness.
Which star type lives the longest?
Red dwarfs are the longest-lived stars; some may be as ancient as the universe itself.
The Red Dwarf Stars of the original series. A red dwarf is defined as a star that has between 0.08 and 0.5 solar masses and is mostly made up of hydrogen gas.
Luminosity and Lifetime. A red dwarf has a very low luminosity and a correspondingly long lifetime.
Nuclear Fusion. Red dwarfs are very slow burners; they can fuse hydrogen for trillions of years.
Life Cycle of Stars. A red dwarf will eventually run out of hydrogen and contract to become a white dwarf.
What are the 7 main types of stars?
The sun is a type of star that has the greatest temperature, which means it radiates the most light. The seven primary types of stars are as follows: O, B, A, F, G, K, and M. However rare but extremely bright O and B stars exist; M stars are more common but faint.
Which star is hotter Mira or the sun?
The Sun, on the other hand, is a little brighter and redder. Mira, on the other hand, is bluer and hotter than the Sun.
What are the 5 types of stars?
- Protostar. A protostar is what comes before a star has formed – a collection of gas that collapsed from a huge molecular cloud.
- T Tauri Stars. T Tauri stars are young protostars that are still in the process of accreting matter from their surrounding disks.
- Main Sequence Stars. Main sequence stars are the most stable type of star; about 90% of all stars in the universe fall into this category.
- Red Giant Stars. Red giant stars are larger and cooler than main sequence stars.
- White Dwarf Stars. White dwarf stars are the end state of most stars.
- Red Dwarf Stars. Red dwarf stars are the longest lived type of star.
- Neutron Stars. Neutron stars are the end state of the most massive stars.
- Supergiant Stars. Supergiant stars are the largest type of star.
Does a supernova occur every time a star dies?
What causes a supernova? The “final hurrah” of a massive star is one type of supernova. This occurs when a star at least five times the mass of our sun goes out with a huge explosion! Nuclear fuel in the cores of huge stars is burned more quickly than it does in smaller stars.
What is the hottest star ever discovered?
WR 102 is the hottest known star, having a heat surface temperature more than 35 times hotter than the Sun.
