Red dwarfs are very interesting Would you like to know more about them Here’s a list of 24 facts about red dwarfs FACT#1 Red dwarfs are the most common star types in the Milkyway galaxy, infarct about 75% of stars in the Milkyway are red dwarfs FACT#2 As a big star dies in a supernova explosion, heavier metals come out from this explosion, which can form red dwarfs, this why they are so common FACT#3 Observing them is not easy because of their low luminosity FACT#4 None of them is visible by the naked eye , from earth FACT#5 The coolest red dwarf have a surface temperature of about 2000 kelvins FACT#6 the smallest one have a radius of about 9% of that of the sun FACT#7 they are very low mass stars , because of which they have low pressure in their core, hence a low fusion rate, which in turn gives them a low surface temperature FACT#8 even the larges red dwarf has a luminosity of about 10%
