Stars "burn" hydrogen related to the amount of pressure on their cores. A larger star has more pressure in it's core and thus has a higher temperature. This extra pressure creates additional nuclear fusion, and thus it uses it's "supply" of hydrogen much faster.
A small star, has less pressure on it's core and can thus last for a long time.

What is the approximate lifetime of a small star?
The approximate lifetime of a small star, like a red dwarf, can range from tens of billions to over a hundred billion years. These stars burn their hydrogen fuel slowly, allowing them to exist for much longer than larger stars, which have shorter lifespans due to their more rapid fusion processes. In contrast, larger stars may only last a few million to a few billion years before exhausting their fuel. Overall, small stars are among the longest-lived objects in the universe.
What is the collective term given to a group of stars?
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
A star's lifetime depends on what?
A star's lifetime depends on its mass. More massive stars have shorter lifetimes, burning through their fuel faster, while less massive stars have longer lifetimes. Additionally, the composition of a star determines how it burns its fuel and influences its lifetime.
Is the sun a small star or a medium star?
The Sun isn't especially large, but is still a little larger than average. But the "average" for stars is skewed a bit by the fact that there are so many small stars. We talk about Betelgeuse and Rigel and Sirius, the biggest and brightest stars, but there are far more dwarf stars than giants.
What star is densest?
The densest stars are neutron stars; these are "dead stars", in the sense that they ran out of fuel and no longer convert energy. However, they still have a large amount of energy left over from the collapse, which they gradually emit.
Which star lives longer giant stars or small stars?
Small stars live longer
How many years does a star lives?
It depends on the size. Small, dim stars live much, much longer than large, bright ones. The expected lifetime of a star like the Sun as a main-sequence star is about 10 billion years.
What is the approximate lifetime of a small star?
The approximate lifetime of a small star, like a red dwarf, can range from tens of billions to over a hundred billion years. These stars burn their hydrogen fuel slowly, allowing them to exist for much longer than larger stars, which have shorter lifespans due to their more rapid fusion processes. In contrast, larger stars may only last a few million to a few billion years before exhausting their fuel. Overall, small stars are among the longest-lived objects in the universe.
How does a large star differ from a small star?
In the size. Also, large stars normally have a hotter core, and produce significantly more energy than small stars; as a result, they don't last very long - after a few million years, the largest stars are burnt out. Note: the key difference for the above is not so much the diameter (which changes over the lifetime of a star), but the mass.
What is the collective term given to a group of stars?
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
How are small and large stars similar?
They are all suns for far off Galaxy's.
A star's lifetime depends on what?
A star's lifetime depends on its mass. More massive stars have shorter lifetimes, burning through their fuel faster, while less massive stars have longer lifetimes. Additionally, the composition of a star determines how it burns its fuel and influences its lifetime.
What characteristics do red stars share?
They are either small and cool and fusing hydrogen or large and hot, fusing helium. The large and hot ones ape read because although they are hot, this heat is radiated over a large surface area. Large red stars are approaching the end of their lives, small, cool red stars will have very, very long lives.
How many stars on China's flag?
There are 5 stars on the flag, one large gold star is arounded by 4 smaller stars. The large one represents the Communist Party of China, while the four small star represents the classes of the country.There are 5 stars. One big star and 4 smaller stars to the right of it.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
How do neutron stars differ from super giant stars?
I suggest you do some reading on both, to get an idea what a neutron star really is, and what a supergiant is. For a start, some differences are: their diameter; their density; the fact that a neutron star no longer produces any energy.
What can be seen on the flag of china?
A large yellow star ringed with small yellow stars.
