They are called Core Burning Stars the smallest one is OGLE-TR-122b.
Degenerate stars
The smallest stars known are red dwarfs, which typically have masses less than half that of our Sun. These stars are the most common in the universe and can be as small as about 8% of the mass of the Sun. Despite their small size, red dwarfs can have long lifespans, burning steadily for billions of years.
Binary stars have the smallest number of stars, consisting of only two stars orbiting each other in a gravitational dance.
No. The sun is larger than about 95% of stars.
The red dwarves.
Degenerate stars
If you mean "stars", the smallest real stars are called red dwarves. Brown dwarves may be smaller still, but since they don't fuse hydrogen-1 into helium-4, it's doubtful whether you should classify them as real stars.
The biggest star that we know of is called: VY Canis Majoris at 2,100 times the size of our Sun. And the smallest star that we know of is called: OGLE-TR-122b at 0.12 solar radii (that's 167,000 km).
The smallest stars known are red dwarfs, which typically have masses less than half that of our Sun. These stars are the most common in the universe and can be as small as about 8% of the mass of the Sun. Despite their small size, red dwarfs can have long lifespans, burning steadily for billions of years.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Binary stars have the smallest number of stars, consisting of only two stars orbiting each other in a gravitational dance.
No. The sun is larger than about 95% of stars.
The very smallest "stars" in the galaxy are brown dwarfs. These are starlike objects that have failed to produce sustained nuclear fusion.
The red dwarves.
It is the smallest and most dormant of all stars.
Mercury is the smallest actual planet of the eight comprising the solar system. It is actually smaller (but more massive) than the moons Ganymede and Titan. Mercury has about 5.5% of the mass of Earth.Before 24 August 2006, Pluto considered the smallest planet of our solar system. On that date, the IAU modified the definition of "planet" and Pluto no longer qualified. It was reclassified as a "dwarf planet." There are a number of smaller objects, including dwarf planets, asteroids, and Kuiper Belt objects (past the orbit of Neptune).Sizes of the Planets (largest to smallest)JupiterSaturnUranus (3rd largest)Neptune (3rd most massive)EarthVenusMarsMercury
The smallest particle of an element is called an atom.
