More evolved worlds
In a world like ours that orbits a star like the sun, we would be temporarily limited by our sun, because the sun is increasing in brightness little by little, within approximately 1 billion years the heat that the Earth will receive from the Sun will be too high to maintain liquid water on the surface, the oceans will begin to transform into gas and water vapor is a tremendous greenhouse gas, more than methane and CO2, what happens is that water vapor, the Earth's climate eliminates it Easily, as soon as there is a little cold, well, it rains or snows, but if not, if it is too hot, water vapor accumulates and continues to increase the greenhouse effect, with which it has been calculated that within 1 billion years the Earth would be uninhabitable.
There are stars that have a much greater capacity to harbor life, they are orange dwarfs, they are not as small as red dwarfs, which are complicated, they are complicated because red dwarfs tend to be quite unstable, they emit powerful flares because they are quite young, a red dwarf can live 100,000 million years or 120,000 million years, no red dwarf has yet died of old age, but they have that problem, that they have powerful flares, they also have another problem, that the habitable zone has to be very close to the star because they are cold stars, so if you are very close to the star, only a few million kilometers from it and that star has a flare, you eat the entire flare, that is what happens, for example, to our closest star, close to Centauri, which has a planet, but the poor thing is burned from the flares.
However, orange dwarfs are a little smaller than the sun, in fact, if we were on a planet that orbited an orange dwarf, we would notice a big difference, the habitable area is a little smaller than the habitable area of a star like the sun, yes, but it is still a fairly large habitable area and the advantage they have is that they can live twice as old as the sun, which means that no orange dwarf has died in the entire existence of the universe.
