The planet, which orbits a star 42 light years away, sits in the so-called Goldilocks Zone, the band around a sun where temperatures are neither too hot nor too cold for liquid water to exist.one of three super-Earth type planets recently discovered orbiting HD 40307, doubling the number of known planets in that system to six.
There are at least 8.8 billion stars with Earth-size planets in the habitable temperature zone.In the Milky Way, about 1 in 5 stars that are like our sun.
- There are about 200 billion stars in our galaxy,
- with 40 billion of them like our sun,
- The planet has a mass at least seven times that of Earth.
- It receives a similar amount of solar energy as Earth gets.
- More than 800 planets have been discovered outside our solar system.
- Those that don't spin are said to be tidally locked, with one half in constant darkness.
- Planets in the zone that rotate, create a day-time and night-time, Earth-like environment.
- Longer orbit of the new planet means that its climate and atmosphere to support life.
