Sentences with phrase «roughly circular orbits»

Planets form in roughly circular orbits level with the plane of the system, but the pulsar planet's orbit is highly inclined.

What's more, the close, roughly circular orbits of Phobos and Deimos are inconsistent with the idea that they were once asteroids that were strong - armed into joining the Martian family by the Red Planet's gravitational clout.

It follows a roughly circular orbit that swings it once around the sun every 286 years.

It's roughly circular orbit (e = 0.16 +0.0.

Planet c may have a minimum mass around 54 + / - 0.7 percent of the mass of Jupiter with a semi-major axis of 3.6 + / -0.1 AUs and a roughly circular orbit (0.10 +0.5 / -0.1) that takes more than 6.5 years (2,391 +100 / -87 days) to complete (Gregory and Fischer, 2010; and Fischer et al, 2001 — in pdf).

It revolves around GJ 1214 at an average distance of 0.014 AU, in a roughly circular orbit (e < 0.27) which it completes in 1.6 days (38 hours), and so the planet must have a very hot equilibrium temperature — updated in 2011 to around 555 kelvin, 539 ° Fahrenheit, or 282 ° Celsius (Desert et al, 2011, page 6).

All the planets remain roughly where they formed, in circular orbits in the same plane.

The Earth's axis wobbles or «precesses» on a 26,000 - year cycle; it changes its average tilt on a 41,000 - year cycle; and it shifts its orbit from being roughly circular to more elliptical on a 100,000 - year cycle.

By matching these isotope ratios to the astronomical cycle — Earth's orbit oscillates between an elliptical and circular path on a roughly 400,000 - year cycle — the researchers found that patterns of glaciation and ice retreat followed the eccentricity of our planet's orbitthey report in the December 22 Science.
