Sentences with phrase «within orbital distances»

Their simulations suggest that at least one planet in the one to two Earth - mass range could have formed within orbital distances of 0.5 to 1.5 AUs around both heavy - element - rich stars; of particularly note, the simulations frequently generated a Earth - like planet in or near Star B's habitable zone (where liquid water could exist on the planet's surface).

To test this idea, Volk selected 12 of Kepler's systems with four or more planets within the orbital distance of Mercury, tweaked their orbits slightly, and simulated what happened next.

An Earth - type planet could have liquid water in a stable orbit centered around 0.036 AU from Star B — well within the orbital distance of Mercury in the Solar System.

Without accounting for infrared heating, the water - zone orbit would be centered within 0.07 AU — well within the orbital distance of Mercury.

The distance from CD - 23 17699 where an Earth - type planet would be «comfortable» with liquid water is centered around only 0.202 AU — within the orbital distance of Mercury in the Solar System.

According to calculations performed for the NASA Star and Exoplanet Database, the distance from Ross 128 where an Earth - type rocky planet may have liquid water on its surface has been estimated to be between 0.06 and 0.11 AU — well within the orbital distance of Mercury in the Solar System.

The average orbital distance of planet «b» from this star is 0.080 AU and so it could have liquid water on its surface, although it moves arount its host star well within the orbital distance of Mercury in the Solar System.

The distance from EV Lac where an Earth - type planet would have liquid water on its surface is centered around 0.165 AU — well within the orbital distance of Mercury's orbital distance in the Solar System.

In their survey of planets within 0.5 to 10 AUs of their host star, the astronomers found that 17 +6 / -9 percent of observed stars had Jupiter - class planets (of 0.3 to 10 Jupiter masses), 52 +22 / -29 percent had Neptune - class planets (of 10 to 30 Earth - masses), and that 62 +35 / -37 percent had super-Earths of 5 to 10 Earth - masses, which is consistent with the conclusion that an average star in the Milky Way should have one or more planets within an orbital distance of 0.5 to 10 AUs, and that there may be some 10 billion Earth - sized planets in the galaxy (ESO press release; Anil Ananthaswamy, New Scientist, January 11, 2012; Jason Palmer, BBC News, January 11, 2012; and Cassan et al, 2012).

Accounting for the relatively greater infrared output of M - stars like Kapteyn's Star, the distance from Kapteyn's where an Earth - type planet would have liquid water on its surface is centered around only 0.158 AU — well within the orbital distance of Mercury in the Solar System.

Not exact matches

Planet «d» - On average, planetary candidate «d» lies about 2.5 AUs from ups And, just within the middle orbital distance of the Main Asteroid Belt of the Solar System.

It moves around Star A at an average distance of less than 0.05 AUs (a semi-major axis well within Mercury's orbital distance) in a near circular orbit (e = 0.23 + / - 0.015) that takes 3.312 days to complete.

The distance from Chi1 Orionis A where an Earth - type planet would be «comfortable» with liquid water is centered within 1 AU — around inside the orbital distance of Earth in the Solar System.

The orbit of an Earth - like planet (with liquid water) around Star B may be centered as close as 0.09 AU — well within the orbit distance of Mercury — with an orbital period of just around 22 days.

Because planets either too close to or too far from their host stars will be at temperatures that cause water either to boil or to freeze, astrobiologists define a «habitable zone,» a range of orbital distances within which planets can support liquid water on their surfaces.

An Earth - type planet could have liquid water in a stable orbit centered around 3.5 AU (within a predicted habitable zone ranging between 2.3 and 4.8 AUs) from Star A — between the orbital distances of the Main Asteroid Belt and Jupiter in the Solar System (NASA Stars and Exoplanet Database).

All three planets are assumed to have highly circular orbits at an orbital distance from HD 40307 that would be well within the orbit of Mercury in the Solar System.

Despite possible orbital eccentricity, planetary candidate «g» average orbit distance of around 0.6 AU should keep it wholly within HD 40307's habitable - zone between 0.4 and 1.0 AU, even if the object is relatively cloudless.

Early in 2002, S2 came very close to the black hole, coming within 17 light - hours or around three times the orbital distance of Pluto from the sun (or 39 AUs).

In the early 1990s, one study found that coplanarity between the orbital and equatorial planes of nearby binaries (within 100 parsecs or 326 ly) that are composed of Sol - type stars (F5 - K5 V) «exists» for binaries with orbital separations up to the average orbital distance of Pluto in the Solar System — roughly 40 times the Earth - Sun distance or «astronomical unit» (AU).
