a planet about six hundred light years away.It is the first planet in a"habitable zone"outside the solar system.That means the planet orbits a star like our Sun,but it is not too close to it,nor too far away.Because of this position,scientists say Kepler22b might have water,one of ...
Recently, the Kepler spacecraft found “22b”, a planet about six hundred light years away. It is the first planet in a “habitable zone” outside the solar system. That means the planet orbits(环绕) a star like our sun, but it is not too close to it, nor too far away. Because ...
In their thorough and entertaining book, Coustenis and Encrenaz also discuss the prospects for life on the 800 or so planetary systems so far discovered around other stars. In 2011, the planet Kepler-22b was discovered 600 light years from Earth and in the habitable zone of its star. But...

Among the exoplanets catalogued so far, a few could match this water world. One such discovery is Kepler-22b. Kepler-22b, at 2.4 times Earth's radius and orbiting within its star's habitable zone, could be a water-covered planet. Credit: NASA...
For example, compared to the previous release, the following code demonstrates that the computation of the position history of 1000 satellites using Two-Body-Keplerian, SGP4, and SDP4 orbit propagators is faster by about 51x, 64x, and 50x respectively. % Create 3 satellite scenario objects. ...
