As an expert in astrophysics, I can tell you that the concept of the "smallest star" in the universe is a bit misleading. Stars come in a wide range of sizes, but the smallest known type of star that is still considered a true star is a red dwarf. Red dwarfs are much smaller and cooler than our Sun. The smallest known red dwarf star is EBLM J0555-57Ab, which is about the size of Jupiter, although it's significantly more massive.

The smallest known star right now is OGLE-TR-122b, a red dwarf star that's part of a binary stellar system. This red dwarf the smallest star to ever have its radius accurately measured; 0.12 solar radii. This works out to be 167,000 km. That's only 20% larger than Jupiter.read more >>+119962023-04-13 10:53:31
