of Kuiper belt objects also indicate a violent past.
The solar system's nine planets follow orbits
around the sun that are shaped like ellipses, or stretched-out circles.
First, a low symmetry reduces the probability of quasi-trapped orbits
by inducing mode mixing of the neutrons so that neutrons reach the boundary defined by their kinetic and potential energy.
It launched Sputnik, the first artificial satellite, into orbit
around the Earth.
The object's orbit
is estimated to have a period of 5,000 years, an elongated, cometlike circuit that stretches into the void beyond the orbits
of Neptune and Pluto.
The model calculations found that objects as large, or even larger, than Sedna could easily form in circular orbits
at distances of 75 to 500 AU, and that their formation time could have been fairly short -- just a few percent the age of the solar system," Stern continues.
Such fringe orbits
have yet to be explored by most planet-hunting techniques.
Although it sometimes comes close to Earth's orbit
, the 14-mile-diameter asteroid is not one of the approximately 150 known planetoids more than one-half mile in diameter whose orbits
actually cross that of Earth.
But there's one distinguishing feature: The motions of moons are discernible as each inches across the sky in synchrony with the planet it orbits
That in turn revealed that the third body is a Jupiter like planet that orbits
the neutron star-white dwarf duo at about the same distance that Uranus orbits
Alluding to comments previously published in the trade press, Gerding added: ``TRW has not patented orbits
in space any more than Thomas Edison patented the radio-frequency spectrum when he received a patent in 1885 for `wireless telegraphy,' the precursor to radio.
If the cluster were still intact as it came within 4 light-years of the core, within the gravitational grasp of the supermassive black hole, it would soon disintegrate, spilling its stars into orbits
around the black hole.
From their orbits
more than 22,000 miles above Earth, they relay voice, television and digital and analog data between user satellites and the satellites' control centers on Earth.
This week, they announced that they had found the first Jupiterlike planet orbiting a star at nearly the same distance that Jupiter orbits
Both planets, like most in our solar system, have nearly circular orbits
