are there any other stars smaller than our our sun, what about their temperatures, hotter or colder?
Hi Jose
There are lots of stars small and colder than our Sun. There a class of stars called Red Dwarfs that are smaller and cooler and redder. There's also a class of objects called Brown Dwarfs which are even smaller and cooler..they don't have enough mass to burn via fusion like our Sun.
