Shadow planet: Strange orbits in the Kuiper belt revive talk of a Planet X in the solar system[ILLUSTRATION OMITTED] Out beyond Neptune, the solar system resembles the deep ocean: dark,...doi:10.1002/scin.2014.186011021Christopher Crockett
The orbits of the four giant planet Jupiter, Saturn, Uranus and Neptune are shown by purple solid circles. The Kuiper Belt (including Pluto) is shown by the dotted light blue region just beyond the giant planets. Sedna's orbit is shown in orange while 2012 VP113's orbit is shown in ...
Planar resonant periodic orbits in Kuiper belt dynamics In the framework of the planar restricted three body problem we study a considerable number of resonances associated to the Kuiper Belt dynamics and located between 30 and 48 a.u. Our study is based on the computation of resonant periodi....

Kuiper-belt objects (KBOs) are an ancient reservoir of comets beyond Neptune's orbit. Some of these objects were recently found to have the reddest optical colours in the Solar System, but the number of objects for which accurate colours were available was too small for any correlation to be...
Although the Kuiper Belt—the icy region of the solar system where Pluto orbits—was once much more crowded, today it has such a low density of objects that collisions between them are ___. A. inconsequential 不重要的 B. ongoing 进行中的 C. ...
The collection of artificial satellites in geostationary orbit is called theClarke Belt. Note that geostationary communication satellites are marvelous for talking to positions on Terra at latitude zero (equator) to latitude plus or minus 70°. For latitudes from ±70° to ±90° (north and south...
. Objects in the Kuiper belt, all of which have mean distances from the Sun greater than that of Neptune, are considered to be comet nuclei. Because of their great distance from the Sun, however, they do not display thecharacteristicactivity of comets. In addition, any object on a non...
This work generates, through a sample of numerical simulations of the restricted three-body problem, diagrams of semimajor axis and eccentricity which defines stable and unstable zones for particles in S-type orbits around Pluto and Charon. Since we consider initial conditions with 0 ¤e¤ 0.99 ...
(125 miles). Other bodies of this size and much larger—e.g.,PlutoandEris—have been observed in theKuiper belt. Most of the objects occupying the Kuiper belt apparently formed in place, but calculations show that billions of icy planetesimals were gravitationally expelled by the giant planets...
