How heavy is a star • It would depends on the mass of original star and the nature of the explosion it cant be much more than about there times the mas it would crate a black hole rather than neutron star! • I believe stars weigh about 150,000,000,000,000,000,000,000,000,000,000 KG.
Supernovas • When a massive star dies, it does so in a spectacular explosion known as a supernova • Supernovas are very rare .Of the roughly 200 stars in our galaxy, only one explodes per century on avarage!
What is a high mass star? • A high mass star is a star which is anything over 8 times the mass of the sun!
Big & small stars! • There are giant stars in space that can be 100 times larger than the sun , there are dwarf stars that can be 100 times smaller than the sun!

Are stars big or small ? • There are giant stars in space that can be 100 times larger than the sun , there are dwarf stars that can be 100 times smaller !
Star facts Stars have hydrogen gas & don’t have solid surfaces , temperatures of almost 3000 to 30000 C. The sun is almost 1.4 million kilometers acrossand it’s just a medium size dstar!
How fast does light travel ? • Light travels at an amazing 300,000 kilometers per second !
Biggest star known • The biggest star known is the hypergiant Cygnus , witch is 810,000 times as bright as the sun !
