Detailed explanation-1: -What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Detailed explanation-2: -The availability of liquid water is the most important factor that makes a planet habitable, because water is a very effective polar molecule and hence an excellent solvent and facilitator for the complex chemistry of life.
Detailed explanation-3: -Without chemicals to make proteins & carbohydrates, organisms cannot grow. Planets without systems to deliver nutrients to its organisms (e.g., a water cycle or volcanic activity) cannot support life. Also, when nutrients are spread so thin that they are hard to obtain, such as on a gas planet, life cannot exist.
Detailed explanation-4: -Right distance from their star. More or less circular orbit. Stable rotational axis. Some water, but not too much. No hydrogen-rich atmosphere. Plate tectonics. Magnetic field. 23-Apr-2021
