Blue Star- blue stars the super giants of the sky. they are much larger than yellow stars (about 3 times bigger) and hotter.
Yellow Stars- yellow stars are a lot smaller and cooler an example is our sun.
Therefore, because blue stars are hotter than yellow- they burn their nuclear fuel a lot faster and live for a shorter time.
The smaller a star the longer it lives. Smaller stars can live up to 200billion years, while a supergiant only lives about 10 billion years. Cooler stars live longer because they don't burn as much energy as a hotter star, while the larger the star, the shorter its lifespan
Yes they do.
There is no such thing as a cold star, as even the lowest-temperature stars are very hot. That said, cooler stars last longer as they burn their fuel more slowly.
No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.
No, big stars die out in a few million years whereas little stars may take billions or even trillions of years to die. This is because big stars use all of their energy up very quickly because they need to use lots of energy to keep them alive.
Dimmer stars generally are just farther away. Their brightness isn't necessarily a factor in how long they live. Their color is actually a better indicator. Yellow stars, like our own sun, burn cooler, and are therefore using their fuel more slowly. This will cause them to live longer. Stars with a red color are burning much hotter, and will therefore use up their fuel more quickly. Blue or white colored stars are burning hotter still!
Small stars live longer
Such stars usually last about 10 billion years.
The smaller stars generally live longer due to less mass & less hydrogen is burned.
Yellow fish assumingly live in water, along with blue, red, and green fish.

Average like the sun ... about 10 billion years. But most stars are dimmer and so live longer, some much longer.
There are two reasons. First, it is fairly unusual for enough gas to gather in one place to form a blue star. It is easier for small amounts of gas together, especially since a star will tend to drive away nearby gas once it forms. Second, blue stars to not live nearly as long as less massive stars do. So if a group of stars of various masses forms together, the white, yellow, orange, and red stars will still exist in 100 million years but the blue ones will not.
