You might enjoy reading about theorized “Superhabitable” planets. A super earth with about twice the mass of Earth would likely have plate tectonics and even more internal heat. Plus, if it orbits a K-type star that’s about 85% of the mass of the Sun, it could remain habitable for tens of billions of years.

By comparison, Earth may be barely habitable. It is amusing to think that we may be living on the galactic equivalent of Australia.

Perhaps the upside is that our gravity well is low enough to make routine spaceflight possible.
