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.
That would be a super-nova
If a red giant star explodes, it can result in a supernova event where the star releases an enormous amount of energy and material into space. This explosion can lead to the formation of elements heavier than iron and can also result in the formation of a neutron star or a black hole, depending on the size of the star.
A Nova or a Supernova.
Rigel in Orion and Deneb in Cygnus are such examples
Many stars are massive enough to form a red giant and then either a white dwarf or neutron star. The best calculations we can do now indicate that one needs at least ten times the mass of the sun to form a black hole. Such stars are not rare.
The giant star
Hypergiant.
A Super Nova.
super giants are a very very big star
super-giant star
one is big one is small

That would mainly depend on the star's mass.
A red giant is when a star becomes very large. A super red giant is when a star becomes very extremely large. People think that in a few billion years, our sun will become a red giant and swallow up earth.
They are big stars.
No. It is, in fact, a super-giant.
