Sentences with phrase «eccentric orbit with»

A substellar companion at that distance would imply an orbital period of around a year, or it could be in a highly eccentric orbit with a much greater average distance from Proxima.

The radial - velocity variations indicate a highly eccentric orbit with a period of 153.9 days.

Not exact matches

Using that as a guide, along with estimates of necessary runoff rates and the duration of valley network formation from other studies, Palumbo showed that model runs in which the Martian orbit was highly eccentric did indeed meet these criteria.

It has an eccentric orbit that is highly inclined with respect to the planets and takes it closer to the Sun than Neptune during a portion of its orbit.

The only known transiting planet with a comparably long orbit, called HD 80606 b, has an extremely eccentric orbit; the distance between HD 80606 b and its star varies greatly throughout the planet's orbit, driving temperature changes of several hundred degrees in a matter of hours.

Now, using the method pioneered by Sir Isaac Newton when he determined the mass of Jupiter, Brown and his colleagues have determined that Eris, a far - flung rocky mass with a wildly eccentric orbit, is 27 percent more massive than Pluto.

With a perihelion of 76 AU (more than twice that of Neptune), Sedna is well beyond the reach of the gas giants and unlike other Kuiper Belt Objects, could not be scattered into its highly eccentric orbit from gravitational interactions with Neptune alWith a perihelion of 76 AU (more than twice that of Neptune), Sedna is well beyond the reach of the gas giants and unlike other Kuiper Belt Objects, could not be scattered into its highly eccentric orbit from gravitational interactions with Neptune alwith Neptune alone.

In particular, I will focus on planets on eccentric orbits, not only because typical exoplanetary systems have been found to contain these, but also because their interactions with debris disks theoretically facilitates the transport of icy bodies within the habitable zone of planetary systems.

Using precise positional data from the National Science Foundation's Very Long Baseline Array (VLBA) and from optical telescopes, Felix Mirabel, an astrophysicist at the Institute for Astronomy and Space Physics of Argentina and French Atomic Energy Commission, and Irapuan Rodrigues, also of the French Atomic Energy Commission, calculated that Scorpius X-1 is not orbiting the Milky Way's center in step with most other stars, but instead follows an eccentric path far above and below the Galaxy's plane.

Although astronomers have detected other EKOs whose orbits lie mostly 50 AUs, these objects have very eccentric orbits, and almost all eventually move inward to within 38 AUs of the Sun, which place them within Neptune's gravitational reach and so these EKOs are generally thought to have been scattered out to their present orbits by a gravitational slingshot with Neptune to become part of the «Scattered Disk.»

A comparison of stellar densities from asteroseismology with densities derived from transit models in Batalha et al. assuming circular orbits shows significant disagreement for more than half of the sample due to systematics in the modeled impact parameters, or due to planet candidates which may be in eccentric orbits.

Traditionally, the solar system has been divided into planets (the big bodies orbiting the Sun), their satellites (a.k.a. moons, variously sized objects orbiting the planets), asteroids (small dense objects orbiting the Sun) and comets (small icy objects with highly eccentric orbits).

To maximize the number of sources occulted by the Moon, a highly eccentric orbit (e ~ 0.93) with a 90.6 hr period and an inclination of 73 ° was chosen.

Bart's example with an astronaut in a very eccentric orbit is good here.

Image that we have a star with a very massive planet in a very eccentric orbit close in.

Now, remember that we postulated a very eccentric orbit, this means that the tidal effect will vary greatly and be much larger when the planet is closest to the star, hence if tides can interfere with or perhaps even control generation of star spots, then the generation of the activity would be synchronized with the orbital period of the star.
