No, main sequence stars last more then a few hundred years. Depending on their mass main sequence stars may last anywhere from several million to several trillion years. Our sun is a main sequence star that is about halfway through its 10 billion year duration.
Actually it can last billions, or even trillions of years.
Low mass stars can last for hundreds of billions of years. Medium mass stars, like our sun will remain on the main sequence for roughly ten billion years. High mass stars, will last for millions of years. By any human measure, a million years is a long time.
Yes. There is a common myth that the stars you see at night have burnt out in the millions of years it takes for their light to reach us.This is not true for two reasons.The stars you see at night are in usually no more than a few hundred light years away, so you see them as they were, at most, a few hundred years ago.Most stars last for billions of years, so a period of a few million years, let alone a few hundred, is not significant.

A main sequence star is a star that is fusing hydrogen in its core. Stars leave the main sequence when they run out of hydrogen and start to fuse heavier elements (starting with helium and finishing with iron). The length of time a star remains on the main sequence depends on how massive the star is. The larger the star the more gravity it has and the tighter this gravity squeezes the core - this makes the core hotter and brings the hydrogen atoms closer together so the fusion process proceeds more rapidly. Thus big stars will only spend a few tens of millions of years on the main sequence while stars the size of our sun will spend ten thousand million years on the main sequence, and smaller stars (red dwarf stars) will spend trillions of years fusing hydrogen.
Yes. Most stars do. Our own star, the sun, is about 4.6 billion years old and is expected to last for about another 5 billion years. The smallest, slowest-burning stars are believed to be able to last for trillions of years. Giant stars, which burn quickly, may only last a few million years.
The biggest stars last only millions, the medium-sized stars last billions, and the smallest stars can last trillions of years.
It is possible but highly unlikely. The stars you see in the sky are light years from Earth, meaning the light takes years to reach us and so we see the stars as they were years ago. For example, if a star is 50 light years away we see it as it was 50 years ago. The nearest star in the nigh sky is just over 4 light years away and most of the ones we see are within a few hundred light years. A few hundred years is insignificant in the life cycle of a star. Even the shortest-lived stars last for millions of years and most last for billions.
No. A few hundred years is insignificant in the lifetime of a star. Even the shortest-live stars last for millions of years. Polaris is a three star system. The main star, Polaris A will probably last for another few tens of millions of years while the other tow stars will last for another few billion years.
Such stars usually last about 10 billion years.
