What ten solar-system objects (planets, moons, other) most suitable for human life?
1. Earth. This already has human life. 2. Mars. This has a decent amount of gravity, decent sunlight, and a reasonably long day. You’d have to live indoors, but it’s doable. 3. Earth’s moon. This is closest to Earth. 4. Mercury. Like the moon, it gets very hot during the day and very cold at night so we’d have to live underground. 5. Asteroids. This have almost no gravity so living here would be almost like floating in space. 6. Venus. We’ve hit a cliff here. We can’t live on Venus with today’s technology. We’d have to “terraform” it, probably by shading it from the sun. It has surface gravity similar to Earth and a good location. 7. Jupiter’s moons. Radiation would be serious concern here and a couple have A LOT of volcanic activity. That’s about as far as you can reasonably plan ahead. Saturn and beyond are so dark and cold you’d need a nuclear powerplant to do anything.
