She found that moving Saturn's orbit 10 per cent closer to the sun or tilting it by 20 to 30 per cent would stretch Earth's orbit so that it would spend part of the year outside the habitable zone, where liquid water can be sustained — or boot it from the solar system entirely (International Journal of Astrobiology, doi.org/w9g).

Recent surveys of faraway stars have focused on finding Earth - size objects orbiting in what is known as the habitable zone, the region where liquid water could presumably exist on the surface of a planet or a moon.

The region in which this planet orbits its star is called the habitable zone, as it is thought that life would most likely form on planets with liquid water.

The habitable zone — sometimes referred to the «Goldilocks» zone by the media and the surface water liquid zone by scientists — is the range of distance from the star in which a planet orbiting it could have liquid water on its surface.

The «goldilocks zone» the area around a star where water would be a liquid on the surface of a planet.
