The smallest star in the universe?
the smallest stars around are the tiny red drawfs.these are the stars with 50% the mass of the sun & smaller

There are well over 1,000 species of the fairyfly. At just 0.139 mm long, they are the smallest insect known to man, and at just 0.15 mm in length, they are the smallest k…nown flying insect. In some areas they are called fairy wasps.
Mercury is the smallest planet in our solar system. We probably won't ever detect any other planets of that size orbiting other stars because they are just so small. W…e may be able to detect perturbations of a star with a small orbiting planet, but we most likely won't be able to get a very accurate measurement of the actual size
The smallest main sequence star detected so far is called OGLE-TR-122b. It has a radius of 0.12 that of our Sun which means it is only 20% larger than Jupiter and has a mass… of about 100 times that. Astronomers describe the smallest star as a "core burning star," like our Sun. But prevailing theory never anticipated such a diminutive star, since the standard fusion model of stars required a minimum gravitating mass considerably greater than that of Jupiter. The smallest non main sequence star is a neutron star with a diameter of 12km - equal to about the length of Manhattan Island from the tip till the end of Central park.

Depending on how you define smallest, the smallest thing in the universe could be a quark or a neutrino, which has a mass barely more than zero.
OTS 44 a brown dwarf 550 light years away in the constellation Chamaeleon. It has a mass of 0.013 solar masses, about 15 times that of Jupiter, or about 1.5 % that of the Sun.… Its radius is about 20% of the Sun. ------- Gliese 623b by comparison is 0.080 solar mass
The smallest stars are called neutron stars. They typically have a diameter of only 12km the smallest star is the neutron star from the word "neutron"
A "quark" - Particle that makes up sub-atomic particles. "An elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles ca…lled hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei." P.S.: The more appropriate QUESTION would be, "What is the smallest KNOWN object in the universe?", as just a few years ago, even the quark wasn't known (ie: the atom was thaught to be the smallest). P.S.S.: though quarks range in size quite drastically, it's safe to say that they exist around 1 × 10−21 m (1 zeptometre). However, there is now evidence that suggests that quantum foam is made up of high-energy virtual particles that are smaller than 1 Planck unit (1.62 × 10−35 m), a level once described as physically impossible to exist beyond.
In the universe In order what is smallest to biggest planet star moon super cluster cluster supernova?
Moon (Although some moons are larger than planets), Planet, (Although some planets are larger than Stars) Star, Solar System, Supernova, Cluster, Super Cluster. Universe.
Universe -> galaxy -> star -> planet
at the moment, the smallest thing in the universe known to man is the neutrino, with a mass of less than 0. this is the opposite of an electron. electrons are one of the three… main things that make up atoms.

Eventually there is Planck Space at 4.222 x 10-101 m Also there is Quantoam foam just smaller than strings and Planck Length/Planck Particle. The Quantoam Foam is 0.000000000…01 yoctometers Strings 1D: 0.000000000016 yoctometers Planck Length: Same as Strings 1D Yoctometer is 1,000,000,000,000,000,000,000,000th of a meter. This number is widely known as a septillionth or 10-24 of a meter and the yoctometer is the smallest known measurement right now but technology will get better and they will finds smaller measurements and smaller things
