500 million planets are there to support human life like earth
Scientists looking for extraterrestrial life concentrate on “Goldilocks Planets,” which are planets that fall within a star’s habitable zone. The temperature is just right due to the planet Earth’s distance from the Sun, water can exist as both a liquid and a gas, and the appropriate combination of chemical components is present to enable the development of complex life forms. The term “Goldilocks planet” refers to other worlds that are believed to share similar characteristics.
There are thought to be 500 million potential Goldilocks planets in the Milky Way alone, so if life can exist elsewhere besides Earth, there are a tonne of other worlds where it might flourish. There could be a staggering diversity of planets that can host life if these figures are applied to all the galaxies in the cosmos. Although there is no proof that life exists elsewhere, there are plenty of areas for it to settle if it does.
