Example text

In 1988 Martin J. Duncan of the University of Toronto, Thomas Quinn and Scott D. Tremaine (both at the Canadian Institute for Theoretical Astrophysics) used computer simulations to investigate how the giant gaseous planets could capture comets. Like Joss, they found that the process worked rather poorly, raising doubts about the veracity of this well-established concept for the origin of short-period comets. Indeed, their studies sounded a new alarm because they noted that the few comets that could be drawn from the Oort cloud by the gravitational tug of the major planets should be traveling in a spherical swarm, whereas the orbits of the short-period comets tend to lie in planes close to the ecliptic.

The 32 objects range in diameter from 100 to 400 kilometers, making them considerably smaller than both Pluto (which is about 2,300 kilometers wide) and its satellite, Charon, (which measures about 1,100 kilometers across). The current sampling is still quite mod- The Kuiper Belt Copyright 1996 Scientific American, Inc. 1 NEPTUNE 0 30 1995 DA2 35 40 45 SEMIMAJOR AXIS (ASTRONOMICAL UNITS) 50 MEAN-MOTION RESONANCE governs the size and shape of the orbits of many Kuiper belt objects. Orbits are described by eccentricity (deviation from circularity) and semimajor axis (red arrow).
