The new model simulates “universes” of stars and planets and then “observes” these simulated universes to determine how many of the planets would have been discovered by Kepler in each “universe.” “Once we know how well we can detect a planet, we can then predict how many other planets like it there are,” Ragozzine said. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. Life may be generated directly on a planet or satellite endogenously or be transferred to it from another body, through a hypothetical process known as panspermia. 3 Minute Read. Given that there are about 40 trillion planets in our universe and that 80% of all stars are similar to our sun and also that we know that other stars have planets orbiting them, then one could guess that there would be billions of other planets in our universe that are capable of sustaining life.
