What's the difference between 'most massive star' and 'the biggest star'?

The R136a1 is the most massive star.



But the VY Canis Majoris is the biggest star.



Can someone please explain how this works... thank youWhat's the difference between 'most massive star' and 'the biggest star'?This is a question of density.



Size and weight are different. A helium balloon is larger than a brick and a brick is more massive (heavy) than a balloon.



So the largest star has the largest volume, while the most massive star has the largest weight, and is therefore more dense.What's the difference between 'most massive star' and 'the biggest star'?Consider a bowling ball and a beach ball: The beach ball is the biggest ball, but the bowling ball is the most massive.



'Massive' refers to how many kilograms of mass an object contains.

'Biggest' typically refers to how many metres wide an object is.



Stellar density is not constant, and varies with age, so a 'wider' star can be lighter than a less wide star.What's the difference between 'most massive star' and 'the biggest star'?Hello.

I am in accord with Sanluen and Bill.

Some stars burn helium which makes them balloon, while others have more mass (made up of more matter).

For instance, a neutron star is a star totally made up of neutrons. It contains so much matter that its gravitational force crushes it so tightly that the atoms are ripped apart and only the fundamental strong force stops further contraction.

Our Sun is larger in size than a neutron star, a neutron star is more massive. A teaspoon of material from a neutron star would weight several tons.What's the difference between 'most massive star' and 'the biggest star'?
The term "biggest" is ambiguous. It could mean the most massive, or it could mean the most voluminous. Unless the source is incorrect, it probably means that VY Canis Majoris is the most voluminous star (i.e. takes up the most space).
