What planets could you live on in this solar system?

Answer 1

Mars is not as close to Earth as Venus is, but it probably is the only planet in our solar system that we can colonize. But living there won't be simple.Mars is poorly suited for human habitation. There's some ice at the poles and perhaps some water in underground repositories. Gravity is only 38 percent as strong as on Earth. The atmosphere is thin and consists mostly of carbon dioxide (95%). So colonists would have to either take air from Earth or make air on Mars. Plants efficiently separate the oxygen bound to carbon and therefore can make air we can breathe, so colonists should take plants along.

The Martian atmosphere is too thin to hold oxygen, which would just escape to space. So the plants would have to be cultivated in greenhouses and the oxygen they produce kept in flasks.

Mars has a very weak magnetic field, and its atmosphere offers little protection against radiation from space. So the Martian colonists would have to build radiation protection into their houses and wear thick suits. Unlike Earth, where most incoming meteorites burn up in the atmosphere, many meteorites crash dangerously onto the surface of Mars.

The Martian weather is awful. It's cold: the average temperature of the Southern Hemisphere is minus 60 degrees Celsius; even at the equator, it's seldom over zero. Winds are fierce and blow at speeds of several hundred kilometres an hour, and storms can last for months. The wind whirls up fine dust that penetrates everything and sticks to all surfaces, which literally would toss sand in the gears of vital mechanical and electronic equipment.

Answer 2

Earth is the only planet in the solar system known to support human life due to its atmosphere, water, and moderate temperatures. Other planets like Mars and potentially Venus could potentially be terraformed in the future to support human life, but currently have harsh conditions. Moons like Titan and Europa also have potential to support human life with some modifications.
