Sentences with phrase «potentially rocky planets»

One of the most interesting set of planets discovered in this study is a system of four potentially rocky planets, between 20 and 50 percent larger than Earth, orbiting a star less than half the size and with less light output than the Sun.

The Gliese 667C system is the first example of a system where such a low - mass star is seen to host several potentially rocky planets in the habitable zone.

Some 39 light - years away, this sun has three potentially rocky planets in its habitable zone and — bonus — four additional rocky planets.

Not exact matches

«In order to figure out whether these planets, the most common in our galaxy, are mostly rocky and potentially habitable or mostly gaseous and probably not very habitable, we have to perform these measurements to learn where exactly this transition occurs and how broad it is.»

San Francisco State University astronomer Stephen Kane and an international team of researchers have announced the discovery of a new rocky planet that could potentially have liquid water on its surface.

By the time Webb is operational, Clampin says, another NASA mission, the Transiting Exoplanet Survey Satellite (TESS), slated for launch in 2017, will already be producing a short list of other potentially habitable rocky planets around nearby small stars.

Astronomers plan to measure masses for at least 50 TESS planets that are smaller than Neptune in the hopes that many of them will have rocky, and therefore potentially habitable, surfaces.

In the Solar System, the asteroid belt contains the leftover building blocks for the terrestrial planets Mercury, Venus, Earth, and Mars, so planetary scientists study the asteroids to gain a better understanding of how rocky, and potentially habitable planets are formed.

To qualify as potentially life - friendly, a planet must be relatively small (and therefore rocky) and orbit in the «habitable zone» of its star, which is loosely defined as a location where water can exist in liquid form on a world's surface.

Ever since the first exoplanet was discovered in 1996, astronomers have been scanning the heavens for another Earth: a rocky planet orbiting its star at just the right distance for it to harbor liquid water and thus, potentially, life.

According to models, the TRAPPIST - 1 system contains three planets in the habitable zone, making it the record holder for stars we know of with rocky planets that could potentially support liquid water, Kaltenegger explained.
