Question

Most stars are

brown dwarves
main sequence
white dwarves
pulsars

Answer 1

90% of stars in our solar system are main sequence stars, meaning that their cores are comprised of hydrogen and helium atoms.
A brown dwarf is like the size of Jupiter, a white dwarf is similar to the sun, but at the end of its life cycle. And lastly, a pulsar looks like a star and appears to be flickering, but is more of a giant sun that is really really really far away
