There are many more red dwarf stars in the universe than astronomers originally thought. A red dwarf is a small star that is about one-tenth the size of our sun. Using more powerful instruments, scientists estimated that, if all red dwarf stars are included, there are approximately 300 sextillion stars in the universe. That’s the number three followed by 23 zeros! The discovery also means there are more planets out there orbiting stars.
