Then, v, [sigma]([alpha]) and [sigma]([beta]) form an asteroidal
triple in G.
1994): Chemical profiles in K / T boundary section of Meghalaya, India: Cometar, asteroidal
Not until years after Hiroshima, Nagasaki, and the repeated irradiation of New Mexico and Kazakhstan were the physics of massive explosions properly understood, and the strangely craterless Tunguska site was subsequently adduced to have been caused by an asteroidal
airburst, an event more common than one might suspect.
titanium, copper, and other metals might be used as construction materials for satellites or space stations; even ordinary rock could prove valuable, as a radiation shield for spacecraft.
Several of my family went along on such an archaeological tour for a couple of weeks into Yucatan a few years ago, well before the time that the archeo-astronomers discovered that the ancient Chicxulub Crater on this peninsula appeared to be the site of an asteroidal
impact which decimated the dinosaurs some 65 million years ago.
In November 2005, the probe landed on the asteroid and collected samples in the form of tiny grains of asteroidal
material, which were finally returned to earth five years later in June 2010.
To date, the only known mini-moon was the small asteroid 2006 RH120 Likely only 3 to 7 meters cross, this asteroidal
fragment was discovered on September 14, 2006, with the Catalina Sky Survey's 0.
Objective: Platinum group element (PGE) abundances & 187Os-isotope compositions determined for magmas of Earth, the Moon, Mars, & asteroidal
bodies place important constraints on planetary evolution but these data, & current analytical approaches, have largely focused on whole-rock analyses.
An apparently asteroidal
object discovered by LINEAR on Jan 15 and posted on the NEOCP was found to have cometary appearance on CCD images taken by P.
Those results set the age boundary for the oldest terrains on Mercury to be contemporary with the so-called Late Heavy Bombardment (LHB), a period of intense asteroid and comet impacts recorded in lunar and asteroidal
rocks and by the numerous craters on the Moon, Earth, and Mars, as well as Mercury.
triple is a set of three pairwise non-adjacent vertices such that there is a path between any pair of them avoiding the neighbors of the third.
For the first time, they used radar to discern asteroidal
features as small as 7.
