Their models showed that if you visited any star with a planet orbiting from the same distance as Earth down to one tenth that, there is about a 38 percent chance (and likely less) that you would run into a planet and moon system similar to Jupiter's four Galilean satellites (Io, Europa, Ganymede and Callisto), with similar ratios of moon to planetary diameters and orbital to planetary radii.

The planet, known as HD 189733b, is a hot Jupiter, meaning it is similar in size to Jupiter in our solar system but in very close orbit around its star.

I'm confident that we'll detect signs of life on exoplanets (planets around other stars) by observing the atmospheres of the planets that we're detecting now — especially those similar to Earth in mass and orbit — and finding oxygen and other chemical signatures there.

To predict when astronomers might find the first planet similar in size to Earth that also orbits far enough from its star to boast liquid water, the team scoured the discovery records of 370 exoplanets.

At the time, astronomers thought this might be caused by the star having two planets with similar orbits.

By monitoring a small, nearby star for 11 years with one of the 10 - meter Keck telescopes in Hawaii and combining the data with 4.3 years of similar observations published by another team, Vogt and his co-authors found two orbiting planets, with respective masses of at least 3.1 times and seven times the mass of Earth.

At the moment, we are able to identify planets with a similar mass and radius to Earth that orbit their stars at the right distance to support liquid water.

«This supports the idea that the star originally had a full complement of terrestrial planets, and probably gas giant planets, orbiting it — a complex system similar to our own.»

NASA said Thursday that Kepler - 452 is the first near - Earth - size planet to orbit in the habitable zone of a star that's similar in size and temperature to our sun.

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.

Orbiting particles should spiral into their star or be scattered or expelled from their orbit — not merge (accrete) to become a planet.a Experiments have shown that colliding particles, instead of sticking together, almost always fragment.b (Similar difficulties exist in trying to form a moon from particles orbiting a Orbiting particles should spiral into their star or be scattered or expelled from their orbit — not merge (accrete) to become a planet.a Experiments have shown that colliding particles, instead of sticking together, almost always fragment.b (Similar difficulties exist in trying to form a moon from particles orbiting a orbiting a planet.)

When looking for habitable worlds, it helps to find a star that has similar qualities to our sun as it's the only star known to have a planet orbiting that's packed with life.

The discovery of planets orbiting other star systems, including similar binary systems (Gamma Cephei), raises the possibility that additional planets may exist in the Alpha Centauri system.
