One of the largest stars known is YZ Canis Majoris.
It is a Red Hypergiant star estimated to be up to 2,100 times the diameter of the Sun.
This gives us a diameter of about 2,923,200,000 km and an area of 9,183,503,644.97 km2.
The earths diameter is 12,742 km and this gives an area of 40,030.17 km2.
This means that it would take 229,414.53 earths to make up the area of YZ Canis Majoris.
These kind of explosions are named (Super nova)After a super nova a Giant star can be transformed to a Neutron star or a Black hole That is a Very Dangerous thing.The Waves of Super nova can be very dangerous and can run many miles further.They can destroy life in near planets.
