luminosity and temperature depend on their size but also on their mass
It's mass and temperature.
Well it depends mostly on the size of the star.
Depends on the size of the molecular cloud. But million to billions.
Massive stars are the center of a distant nebula. The massive stars are formed as the gas in the interstellar medium collapses under its own weight. The size of a nebula depends on the size of the original gas cloud.
It depends on its size. Smaller stars- main-sequence, red giant, planetary nebula, white dwarf, black dwarf Bigger stars- main-squence, red giant, supernova, neutron star.
It depends on the size of the elliptical gallery, but you may be sure that there are many billions of stars in one.
Nope. It depends on how much matter the star was immersed in during its formation. More matter equals more size and vice versa.
There are countless stars.
IT all depends on which star you are talking aboutand what its size is because not all stars are the same .super giants are bigger than the sun
The size of stars depends on their mass and the stage of their life cycle. Constellations are just stars which happen to lie in the same general direction from Earth, and have nothing really to do with each other. Apparent brightess of a star or galaxy is the result of its intrinsic brightness and its distance from us.
The sun is larger than about 95% of stars in the galaxy.
No.
