Sentences with phrase «planetary candidates around»

Not exact matches

Based on astrometic as well as high - cadence radial velocity measurements, planetary candidate «c» appears to have around 14.0 +2.3 / -5.3 times the mass of Jupiter (McArthur et al, 2010).

Planetary candidate «b» has around 5.35 ± 0.75 Earth - masses and an orbital period that is a little longer than 11.4 days, which appears to be relatively circular (e = 0.12 +0.08 / -0.06).

It is possible, however, that the presence of massive planetary candidate c at an orbital distance around two AUs could disrupt the orbital stability of an Earth - mass planet in the habitable zone.

Sunset on planetary candidate «c» around Gliese 667 / MLO4 C with binary stars A and B in the darkening sky (more), as imagined by Calçada.

Located towards Constellation Libra, the Gliese 581 system is now believed to have at least six planetary candidates, of which the «potentially habitable» planet has been designated as Gl 581 «g.» This planetary candidate is estimated to have between 3.1 and 4.3 Earth - masses and between 1.3 and 1.5 times Earth's diameter, with a greater surface gravity of around 1.1 to 1.7 g.

Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).

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.
