How many habitable planets are there? Water is the basis of life in any part of the universe. So potentially inhabited planets must have liquid water on them to support life. An incredible number of circumstances must come together for this. The planet must be in the habitable zone of the star. A little closer to the star, and the water will evaporate, leaving no chance for oceans and seas to form. This is what happened on Venus. Too far from the star, and the planet becomes too cold. Water can only exist in the form of ice on the surface and there just might be liquid water deep below. Neptune is one example of this.
In our galaxy alone, there are countless stars. Really you can’t count on them. Near each of them may be a planet. They are called exoplanets. And some of them may be in the habitable zone and have everything for life to form on them. From a list of 4,500 known exoplanets, scientists have identified 24 that can be superhabitable. This is the type of planet that is suitable for the existence and evolution of life even more than the Earth!
