Interesting facts about stars:

Heavy stars blow up and make heavier elements like gold. So, every bit of gold you’ve ever seen, worn, or touched came from the dying explosion of a star. Other elements made in supernovae include anything on the periodic table heavier than iron

Heavy stars blow up when they start fusing iron. Meaning, the iron in your frying pan, car, and your blood killed a star at least 3 times the mass of the sun.

Some massive stars that die end up compressing all their mass into a star about 6 miles across, or about the size of a city. This is called a neutron star.

To put this in perspective, these stars start out 3 times as big as our sun and all of their mass is crushed into something the size of a city. The space between atoms is squished away, and the protons and electrons combine to form neutrons. 

Neutron stars are literally as dense as atomic nuclei

Most stars come in pairs

The most common stellar type is a red dwarf, which is a small, red, dim, cool star.
