Whether a planet is habitable — or can host life — depends on a complex network of interactions among the planet, other planets in its solar system, and the star they orbit. The standard definition for a habitable planet is one that can sustain life for a significant period; based on our solar system, life requires liquid water, energy, and ...

Credit: NASA. Surprisingly, the slow, protracted growth of Earth, the interaction between Jupiter and Saturn, and the giant impact that formed our Moon may have been decisive factors in making a world that is hospitable to living beings. But, as astronomers are finding out, there are some very weird exoplanets out there.
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life. Planetary habitability is the measure of a planet 's or a natural satellite 's potential to develop and maintain environments hospitable to life. [1] Life may be generated directly on a planet or ...
The habitable zone is the not-too-hot, not-too-cold region around a star where liquid water can exist on a planet’s surface. Liquid water is a key ingredient for life as we know it, so exoplanets in their stars’ habitable zones are compelling places to search for life. In certain cases liquid water can exist outside of a star’s habitable ...
The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets’ surfaces. Habitable zones are also known as Goldilocks’ zones, where conditions might be just right – neither too hot nor too cold – for life. When searching for […]
Jan 24, 2020 · A habitable planet is one that can sustain life as we know it for billions of years. A planet’s ability to harbor life results from the complex interplay between its host star, its own orbit and rotation, and the make-up of its surface and interior. One required ingredient for habitability is liquid water, so the planet must orbit in the ...

In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface – is an exciting discovery in the search for life on other worlds.
