Because sibling stars are so similar compositionally to our own sun, astronomers believe there's at least a small chance these stars could have life - sustaining planets orbiting them.

Not exact matches

Although the world orbits too close to its sun to sustain life, the finding is a milestone in the quest to find out how common Earth - sized, habitable planets really are.

In response to the 1993 failure of the Mars Observer mission — a billion - dollar, decade - in - the - making probe that mysteriously lost contact with ground controllers just before it was scheduled to go into orbit around the planet — NASA administrator Daniel Goldin decided to shift to smaller, less expensive spacecraft and create a sustained exploration campaign by sending one or two probes to Mars at every launch opportunity.

During the relatively brief, combined giant phases of the two stars at present, however, a planet could orbit the Aab pair far enough out for the two stars to act as a single gravitational source and near enough for it to receive enough energy to sustain life, possibly around 12.5 AUs out from the binary.

Around smaller, less massive and dimmer dwarf stars, however, planets would have to orbit closer in order to sustain a surface temperature that is warm enough to keep water liquid and so the star would appear larger in the sky.

It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life.

As the number of confirmed and cataloged heavenly bodies has swelled in the past twenty one years, we have sought to learn more about the conditions on these planets: the temperatures, the atmospheres, their core composition, how they orbit their respective stars, and ultimately, whether any are capable of sustaining life.

As in our Solar System, these orbits receive too much irradiation and the planet surfaces are too hot to sustain liquid water.

But when a billionaire astronomer discovers a planet capable of sustaining life orbiting Alpha Centauri, he plans to build a rocket to transport a small group of people to the planet in order to populate it and insure survival of the human race.
