Sentences with phrase «in synchronous rotation»

Such a planetary orbit is likely to be in synchronous rotation with its host star, so that one side is always facing the star with perpetual daylight while the other side is in perpetual darkness.

Synchronous rotation can occur as a result of tidal forces from gravitational interactions between two orbiting bodies (Earth's moon is an example of an object in synchronous rotation, so that we only ever see one side from the ground).

Planets in the habitable zone of low - mass, cool stars are expected to be in synchronous rotation, where one side of the planet always faces the host star (the substellar point) and the other side experiences perpetual night (the anti-stellar point).

Not exact matches

Most inner moons of planets have synchronous rotation, so their synchronous orbits are, in practice, limited to their leading and trailing Lagrange points.

The theory that Mercury's rotation was synchronous became widely held, and it was a significant shock to astronomers when radio observations in the 1960s questioned this belief.

Furthermore, they are locked in a mutual synchronous rotation while having an almost circular, no - eccentric orbit, which disfavor the formation of any currently active geological processes on their surfaces or interiors.

The problem with planets orbiting M - dwarfs is that they are prone to fall into «synchronous rotation» so that one side of the planet always faces the star, while the other side remains in perpetual darkness.

Planets with such orbits are also more likely to have greater orbital eccentricity which if not too large can in turn can contribute to non synchronous rotation such as 3:2 or even 2; 1 resonances, as seen in Mercury with an orbital eccentricity of 0.2.

The other factor that arises from this is that CMEs, of all the various dangerous stellar eminations, appear to be most responsible for planetary atmospheric erosion so anything that mitigates their effect has got to be good in terms of planetary habitability and most of all in M dwarf systems where the «habitable zone» is close to the star and well within the region of synchronous rotation.

These observations also confirm that Titan's rotation is in fact synchronous like most of Saturn's other moons.

Moreover, the star seems to be depleted in lithium because it has maintained comparably dynamo - induced, chromospheric activity resulting from a relatively fast, synchronous (tidally - locked) rotation with its companion and so it may have lost about 10 percent more of its matter than would a single star of its mass and age (Strobel et al, 1994).
