The Big Dipper is not a single star but asterism made up of seven stars from the constellation Ursa Major. These stars have varying lifespans, with the most massive ones burning out much sooner than the less massive ones. While the brighter stars in the Big Dipper, like Dubhe and Merak, are expected to last for millions of years, they will eventually exhaust their fuel and evolve into different stellar phases. However, this process will take place over many thousands to millions of years, so the Big Dipper will not "burn out" in any near future timeframe.
