when does Halley's Comet passes by the earth every
The sun is a star itself. The sun is actually a very small star. There are stars that are WAY bigger then the sun.Like the VY Canis majoris star. The sun is invisible compared to that super giant star.
A Giant is a star up to 10 times larger than our SunA Super giant is a star 10 times larger than our SunA white dwarf is a stellar remnant about 100 times smaller than our Sun.
The super nebula hypothesis proposes that massive stars can form in areas where the gas density is high enough to trigger the formation of multiple stars within a single giant molecular cloud complex. This hypothesis suggests that these super nebulas are responsible for the formation of massive star clusters seen in the universe.
Rigel in Orion and Deneb in Cygnus are such examples
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star

They are big stars.
Super giants are more massive and have larger radii than giant stars. Super giants are in a more advanced stage of stellar evolution compared to giant stars. Both types of stars eventually exhaust their nuclear fuel and go on to evolve into other stages, such as supernovae or white dwarfs.
Big huge stars
because giant and supergiant stage is very short

Some examples of supergiant stars are Rigel, Deneb and Betelgeuse.
Some of the SUPER GIANT stars are Sirius,Sun,Rigel,Betelgeuse,and procyon.
