The stars in Ursa Minor, including Polaris, vary in their lifespans based on their mass and evolutionary stage. Generally, main-sequence stars like Polaris can have lifespans ranging from tens of millions to several billion years. Polaris itself is a supergiant and will likely live for a few more million years before exhausting its nuclear fuel. Other stars in the constellation may have varying lifespans, with some potentially existing for billions of years longer, depending on their individual characteristics.
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
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.
Smaller stars, like red dwarfs, typically live much longer than giant stars. While giant stars have shorter lifespans due to their rapid consumption of nuclear fuel, smaller stars can burn for billions of years. For example, a red dwarf can last for tens to hundreds of billions of years, while a massive star might only live for a few million years before exhausting its fuel and ending in a supernova. Thus, smaller stars have a significantly longer lifespan compared to their giant counterparts.
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.
Some of the constellations visible all year long from the northern hemisphere include Ursa Major (containing the Big Dipper), Ursa Minor (containing the Little Dipper with Polaris, the North Star), and Cassiopeia. In the southern hemisphere, constellations like Centaurus and Crux (Southern Cross) remain visible throughout the year.
If you live in the northern hemisphere, Ursa Minor can be seen in every month of the year. It is one of the constellations that never sets, so it can be seen all year round.If you live in the northern hemisphere, Ursa Minor can be seen in every month of the year.

Small stars live longer
If you live in the northern hemisphere, you can see it year round - it is circumpolar. If you live in the southern hemisphere, you can't see it at all.
The smaller stars generally live longer due to less mass & less hydrogen is burned.
If you live in the USA or Europe, they're most likely Ursa Major, Ursa Minor, the Big and Little Dippers, Cassiopeia, Draco, Cepheus, and maybe Perseus.

Average like the sun ... about 10 billion years. But most stars are dimmer and so live longer, some much longer.
The smaller stars
Smaller stars, like red dwarfs, typically live much longer than giant stars. While giant stars have shorter lifespans due to their rapid consumption of nuclear fuel, smaller stars can burn for billions of years. For example, a red dwarf can last for tens to hundreds of billions of years, while a massive star might only live for a few million years before exhausting its fuel and ending in a supernova. Thus, smaller stars have a significantly longer lifespan compared to their giant counterparts.
If you are 18 you are no longer a minor and can choose to live with either parent (or neither).
