The Secrets Minerva And Its Two Moons
2011-10-06 08:30:47

Since the discovery of its two moons, the triple asteroid Minerva has been the focus of space and ground-based telescope studies that have attempted to unravel the secrets of this intriguing system. A multiple-telescope campaign has now revealed that Minerva is unusually round for an asteroid, and has a possibly unique structure.  The campaign to “weigh” the asteroid and derive its density and other characteristics was undertaken by an international team of planetary...

Berkeley -- A bound pair of icy comets similar to the dirty snowballs circling outside the orbit of Neptune has been found lurking in the shadow of Jupiter. Astronomers at the University of California, Berkeley, working with colleagues in France and at the Keck Telescope in Hawaii, have calculated the density of a known binary asteroid system that shares Jupiter's orbit, and concluded that Patroclus and its companion probably are composed mostly of water ice covered by a patina of dirt....

One of the thousands of minor planets orbiting the Sun has been found to have its own mini planetary system. Astronomer Franck Marchis (University of California, Berkeley, USA) and his colleagues at the Observatoire de Paris (France) [1] have discovered the first triple asteroid system - two small asteroids orbiting a larger one known since 1866 as 87 Sylvia [2]. "Since double asteroids seem to be common, people have been looking for multiple asteroid systems for a long time," said Marchis....

University of California, Berkeley, assistant research astronomer Franck Marchis and his colleagues at the Observatoire de Paris have discovered the first triple asteroid system - two small asteroids orbiting a larger one known since 1866 as 87 Sylvia. Because 87 Sylvia was named after Rhea Sylvia, the mythical mother of the founders of Rome, Marchis proposed naming the...

LONDON -- Scientists have spotted an asteroid with more than one moon -- the first discovery of its kind. Astronomers found a second moonlet orbiting 87 Sylvia, a heavenly body zooming around the sun in the asteroid belt between Mars and Jupiter, according to a Nature magazine report. Sylvia was previously thought to be one of 60 asteroids with just one moon, said University of California astronomer Franck Marchis, whose team made the discovery in March. "We were very excited -- it was the...
