Small Asteroid Will Safely Pass Earth
2014-03-06 12:52:56

NASA's Jet Propulsion Laboratory An asteroid about 25 feet (8 meters) across will safely pass Earth at about 1:21 p.m. PST (4:21 p.m. EST) today, March 6, approaching us six times closer than the moon. This distance, though not unusual, is closer than the Earth flyby of a larger asteroid on Wednesday afternoon, March 5. This afternoon's flyby object, asteroid 2014 EC, was discovered on March 5 by the Catalina Sky Survey near Tucson, Ariz. Its closest-approach distance, about 38,300...

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...

The asteroid belt between Mars and Jupiter is often depicted as a dull zone of dead rocks with an occasional wayward speedster smashing through on its way toward the sun. A new study appearing in the Aug. 26 issue of the journal Nature paints a different picture, one of slow but steady change, where sunlight gradually drives asteroids to split in two and move far apart to become independent asteroids among the millions orbiting the sun. "This shows that asteroids are not inert, dead bodies...

Asteroids with moons, which scientists call binary asteroids, are common in the solar system. A longstanding question has been how the majority of such moons are formed. In this week's issue of the journal Nature, a trio of astronomers from Maryland and France say the surprising answer is sunlight, which can increase or decrease the spin rate of an asteroid. Derek Richardson, of the University of Maryland, his former student Kevin Walsh, now Poincar© Fellow in the Planetology Group in...

Once considered just your average single asteroid, 2001 SN263 has now been revealed as the first near-Earth triple asteroid ever found. The asteroid -- with three bodies orbiting each other -- was discovered this week by astronomers using the radar telescope at the National Science Foundation's (NSF) Arecibo Observatory in Puerto Rico. Cornell and Arecibo astronomer Michael C. Nolan said he and his colleagues made the discovery when they obtained radar images Feb. 11. The group subsequently...

Combining precise observations obtained by ESO's Very Large Telescope with those gathered by a network of smaller telescopes, astronomers have described in unprecedented detail the double asteroid Antiope, which is shown to be a pair of rubble-pile chunks of material, of about the same size, whirling around one another in a perpetual pas de deux. The two components are egg-shaped despite their very small sizes. The asteroid (90) Antiope was discovered in 1866 by Robert Luther from...

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....

Berkeley -- One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own. 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...

Dactyl Asteroid -- Dactyl, discovered in 1993, is a tiny asteroid (diameter 1.4 km) that orbits asteroid 243 Ida. The origins of Dactyl are unclear. The two main theories are that it and Ida formed at the same time, and that it was knocked loose by a later impact. Both have problems. Dactyl, found by the Galileo probe was the first asteroid moon discovered. ----- NASA Click here to learn more on this topic from eLibrary:

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
