Sentences with phrase «other planetary objects»

A new study led by Western University's all - star cosmochemist Audrey Bouvier proves that the Earth and other planetary objects formed in the early years of the Solar System share similar chemical origins — a finding at odds with accepted wisdom held by scientists for decades.

With the discovery of water ice on other planetary objects, scientists are abuzz over the probability of the presence of — and the prospect of supporting — life beyond the boundaries of planet Earth.

But the new evidence comes from a pair of respected planetary scientists, Konstantin Batygin and Mike Brown of the California Institute of Technology (Caltech) in Pasadena, who prepared for the inevitable skepticism with detailed analyses of the orbits of other distant objects and months of computer simulations.

For planetary scientists like Jackson, being able to observe objects like these may yield important clues about how planet formation works in other star systems.

He points out that gravitational tugs from other massive planets or stellar interlopers might have ejected the objects from planetary systems.

However, many others argue that only planemos that directly orbit stars should qualify as planets, preferring to use the terms «planetary body,» «planetary mass object» or «planemo» for similar free - floating objects (as well as planet - size moons).

This definition is based in modern theories of planetary formation, in which planetary embryos initially clear their orbital neighborhood of other smaller objects.

NASA's Planetary Defense Coordination Office is charged with monitoring the paths of asteroids and other objects with orbits that could send them on a crash course with Earth, and planning for response to an actual impact threat.

In the description of the DE200 planetary ephemeris, it is pointed out that, contrary to all the other objects in the computation which use the Solar system barycentre, the orbit of our own moon is computed relative to the Earth - Moon barycentre, because then, the orbit integration will behave nicer numerically — which is good, as the Moon is an object of special interest.
