Did a planetary wobble kill the dinosaurs?
by Nicola Jones
New Scientist
June 27 2001
Bruce Runnegar from the University of California at Los Angeles' Center for Astrobiology... and his colleagues used computer models to map out the Solar System for the past 250 million years. In particular, they looked at the perihelion of each planet - the point in its orbit where it is closest to the Sun. The perihelion of Earth rotates around the Sun with a period of hundreds of thousands of years. Because of subtle tugs and pulls between the planets, this period changes slightly with time... Their model suggests one of these blips significantly changed Mercury's orbit 65 million years ago. This wobble would have pulled at the asteroid belt, increasing the chances that asteroids in the Hungarias region would be knocked out of place. Now the researchers are running a fresh set of models to see how much the orbits of these asteroids changed. It wouldn't have been enough to send a shower of asteroids into the Earth, but Runnegar says the wobble could have sent a single asteroid onto collision course with our planet... Now he is planning to run his models forward in time, to see when the next potentially catastrophic planetary wobble will be.

A Star Like Our Own
by Bill Christensen
29 April 2005
An asteroid belt may have been found surrounding a star much like our own Sun, according to Dr. Charles Beichman of CIT. His team used NASA's Spitzer Space Telescope to make the discovery. If confirmed, this would be the first asteroid belt detected around a star that is about the same age and size as our Sun. If true, it could offer a rare look at a star system that closely resembles our own... According to the astronomers, it is possible that a giant comet, as big as the planet Pluto, got knocked into the inner solar system and is slowly boiling away, shedding dust in the process. "The 'super comet' theory is more of a long shot," Beichman said, "but we'll know soon enough." Future observations of the star using Spitzer and ground-based telescopes are expected to conclude whether asteroids or comets are the source of the dust.
Artist's conception of the system shows the view from a planet that might exist in the system. Note the asteroid collision in the foreground - this replenishes the dust detected by the Spitzer telescope.

Planets Found in Potentially Habitable Setup
by Ker Than
17 May 2006
Three medium-sized planets of roughly the same mass as Neptune have been discovered around... HD 69830, a star slightly less massive than the Sun located 41 light-years away in the constellation Puppis (the Stern)... previously discovered multi-planet solar systems besides our own contain at least one giant, Jupiter-sized planet... The outermost planets is located just within the star's habitable zone, where temperatures are moderate enough for liquid water to form, and the system also contains an asteroid belt. The newly discovered planets have masses of about 10, 12 and 18 times that of Earth and they zip around the star in rapid orbits of about 9, 32 and 197 days, respectively... Recent observations by NASA's Spitzer Space Telescope last year revealed that HD 69830 also hosts an asteroid belt, making it the only other Sun-like star known to have one.

Small Rocky Planet Found Orbiting Normal Star
by Ker Than
25 January 2006
Its orbit is farther from its host star than Earth is from the Sun. Most known extrasolar planets reside inside the equivalent of Mercury’s orbit. The planet is estimated to be about 5.5 times as massive as Earth and thought to be rocky. It orbits a red dwarf star about 28,000 light-years away. Red dwarfs are about one-fifth as massive as the Sun and up to 50 times fainter... Prior to this discovery, the smallest extrasolar planet found around a normal star was about 7.5 Earth masses. Earth-sized planets have been detected, but only around dying neutron stars... The planet and star are separated by about 2.5 astronomical units (AU). One AU is equal to the distance between the Earth and the Sun. Until now, no small planet had been found farther than 0.15 au from its parent star... "Microlensing should have discovered dozens of Jupiters by now if they were as common as these five-Earth-mass planets," said study co-author David Bennett. That suggests most of our galaxy’s planets are small and rocky. This prediction agrees with the standard model for solar system formation, known as the "core accretion" model.

The Damocloids
by David Jewitt
Last updated June 2005
My specific definition is that "a Damocloid is any point-source object having a Tisserand Parameter with respect to Jupiter less than or equal to 2". By this definition, there are 21 known Damocloids as of 2004 October. Here is a list of the first 20 Damocloids... Damocloids are the inactive nuclei of Halley Family Comets... some objects identified as Damocloids by the above criterion have subsequently developed comae... the distribution of inclinations of Damocloids is indistinguishable from that of the Halley Family Comets, even though the Tisserand selection criterion does not require that this be the case... about 25% of the Damocloids possess retrograde orbits, unlike any other asteroids... The albedos of four Damocloids have been measured and they are consistent in being amongst the lowest recorded for any Solar System objects (albedos are a few %). The Damocloids are extremely dark. The surfaces are redder than sunlight but the ultrared matter that is found on many Kuiper Belt Objects and Centaurs is not present on the Damocloids... The known examples are of modest size, with a median radius of 8 km.Origin of Trans-Neptunian Asteroids
by Tom Van Flandern
Meta Research Bulletin
Volume 4, Number 3, 1995/09/15
The distinction between comets and asteroids has become rather blurred over the past decade because no single characteristic uniquely identifies a body as either with certainty. For example, debate still rages over whether the Jupiter impactor, Shoemaker-Levy 9, was a comet or an asteroid. Despite having very different origins in conventional models, comets and asteroids have continued to display similar reflectance spectra, albedos, size ranges, etc. Comas and tails are the best guides we have to indicate that an object is a comet. But many comets display no tails; indeed, virtually all of them beyond Jupiter do not. And some comets have lost their comas, becoming completely asteroidal in appearance, while some asteroids have suddenly begun to exhibit comet-like activity, including the surprise appearance of a tail in one case.
Highly elongated orbits used to be associated exclusively with comets until the discovery of some unusual objects without coma or tail that therefore appear to be asteroids, yet moving in highly elongated, planet-crossing orbits. Pholus is one such object. The object Chiron is another example of the dilemma, since it was first assumed to be a large asteroid in a planet-like orbit crossing the orbits of Saturn and Uranus. When it was later found to have brightness variability, many astronomers began to call it a comet.

Extreme Kuiper Belt Object 2001 QG298
and the Fraction of Contact Binaries
by Scott S. Sheppard and David Jewitt
Astronomical Journal
pdf version
Extensive time-resolved observations of Kuiper Belt object 2001 QG298 show a lightcurve with a peak-to-peak variation of 1.14 +-0.04 magnitudes and single-peaked period of 6.8872 +- 0.0002 hr. The mean absolute magnitude is 6.85 magnitudes which corresponds to a mean effective radius of 122 (77) km if an albedo of 0.04 (0.10) is assumed. This is the first known Kuiper Belt object and only the third minor planet with a radius > 25 km to display a lightcurve with a range in excess of 1 magnitude. We find the colors to be typical for a Kuiper Belt object (B-V = 1.00 +- 0.04, V-R = 0.60 +- 0.02) with no variation in color between minimum and maximum light. The large light variation, relatively long double-peaked period and absence of rotational color change argue against explanations due to albedo markings or elongation due to high angular momentum. Instead, we suggest that 2001 QG298 may be a very close or contact binary similar in structure to what has been independently proposed for the Trojan asteroid 624 Hektor. If so, its rotational period would be twice the lightcurve period or 13.7744 +- 0.0004 hr. By correcting for the effects of projection, we estimate that the fraction of similar objects in the Kuiper Belt is at least 10% to 20% with the true fraction probably much higher. A high abundance of close and contact binaries is expected in some scenarios for the evolution of binary Kuiper Belt objects.

Researchers explain gas planet satellite systems
Southwest Research Institute
June 14, 2006
Jupiter's four Galilean satellites are each roughly similar in size, while Saturn has one large satellite together with numerous much smaller satellites. Even so, the total mass in both satellite systems is about a hundredth of one percent (0.0001) of the respective planet's mass. The Uranian satellite system structure is similar to that of Jupiter, and it also exhibits the same mass ratio. In contrast, the large satellites of solid planets contain much larger fractions of their planet's masses, with the Moon containing 1 percent (0.01) of the Earth's mass, and Pluto's satellite, Charon, containing more than 10 percent (0.1) of its mass.

Stars Swallow Planets and Researchers Have Proof
by Harald Franzen
May 10, 2001
A light spectrum analysis of HD82943—a star slightly hotter and larger than the sun, harboring its own planetary system—revealed that it contained traces of an isotope of lithium called Lithium-6, or 6Li. Although 6Li is common in planets, it burns up quickly in stars after they are born and thus shouldn't exist in a star like HD82943... To confirm their theory, the scientists looked at another star that shared HD82943's characteristics except that it did not have planets. In keeping, they found that did not have 6Li in its spectrum. The researchers hope that this finding will help to explain how so-called exoplanets form and if this kind of cannibalism is a common process.
