Sentences with phrase «such orbital periods»

Not exact matches

Little is known about these faraway worlds beyond bulk properties such as their orbital periods, estimated masses and, on relatively rare occasions, their diameters.

At that distance from the star, such a planet would have an orbital period of about 124 days, or around a third of an Earth year.

Such a planet would have an orbital period of less than five days and would be tidally locked with respect to Star B.

At that distance from the star, such a planet would have an orbital period of around 4.7 Earth years.

The parent comet (Tempel - Tuttle) has an orbital period of a bit more than 33 years, and so we see storms when the Earth happens to pass close behind the comet, such storms lasting only a few hours.

Such a planet would have an orbital period of around 1.6 years.

At that distance from the star, such a planet would have an orbital period of about 202 days — less than two thirds of an Earth year.

Such a planet would have an orbital period of around 1.3 Earth years.

Hence, Earth - type life around flare stars may be unlikely because their planets must be located very close to dim red dwarfs to be warmed sufficiently by star light to have liquid water (between 0.02 and 0.05 AU for Wolf 424 A and B with an orbital period in 3 and 12 days), which makes flares even more dangerous around such stars.

The progression toward smaller planets at longer orbital periods with each new catalog release suggests that Earth - size planets in the Habitable Zone are forthcoming if, indeed, such planets are abundant.

During the orbital period of such a planet of 0.6 (3) a, an observer on the planet would see this intensely bright companion star circle the sky just as humans see with the Solar System's planets.

At that distance from the star, such a planet would have an orbital period of almost 324 days — nearly an an Earth year.

Assuming that 15 Sge has a mass equal to Sol's, then such a planet would have an orbital period of about 450 days, or just over 1.2 years.

At that distance from Epsilon Indi and assuming that it has 0.77 Solar - mass, such a planet would have an orbital period of around 199 days (or a bit over half an Earth year).

At that distance from Star A and assuming that it has 1.1 Solar - mass, such a planet would have an orbital period of just under 1.5 years.

Assuming that Tau Ceti has 92 percent of Sol's mass, such a planet would have an orbital period under 240 days — less than two - thirds of an Earth year — at that distance from the star.

At that distance from the star, such a planet would have an orbital period close to 2.3 Earth years (835 days).

Subsequently, Heintz (1996, page 411) suggested that such a companion to Star Ba would have to have a mass of at least half Sol's to reach detectable brightness, and that, among other orbital requirements, Bc's period would have to be less than an Earth year in order to account for the absence of effects on Ba's radial velocities and positions.

Almost 1 percent of stars have such giant planets in very close orbits, with orbital periods of less than one week.

At that distance from the star and with 0.29 Solar - mass, such a planet would have an orbital period exceeding 45 day (or 0.124 Earth years).

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).

I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).

Individual discrepancies have been explained, for example, through interactions between other orbital frequencies such as obliquity and the 413,000 - year period of eccentricity but a unified explanation is lacking.

The baseline or ambient temperature at this time during the current inter-glacial (Holocene) period is entirely attributed to the combination of various natural celestial cycles such as solar energy output, and orbital mechanics of axial tilt, procession, and positions of the hemispheres during progression of the orbital ellipse.
