Small Asteroid Regolith Formed By Thermal Fatigue
2014-04-04 06:21:44

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles. New research from researchers at the Observatoire de la Côte d'Azur, Hopkins Extreme Materials Institute at Johns Hopkins University, Institut Supérieur de l'Aéronautique et de l'Espace and Southwest Research Institute (SwRI), have now determined that this layer is formed by...

Citizen Scientists Wanted To Observe Asteroid Blot Out A Star
2014-03-17 08:49:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Millions of Americans may be able to catch a space rock darkening the night sky this Thursday as the brightest visible star vanishes before our very eyes. If you live in the Northeast and the skies are clear, you may want to go out and look up at around 2 a.m (EDT) on March 20. If by chance the skies are clear, then you will want to look to the western skies toward the constellation Leo and hunt down the bright star known as...

[ Watch the Video: The Breakup of Asteroid P/2013 R3 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the Astrophysical Journal Letters say they witnessed an asteroid breakup into as many as 10 smaller pieces. The team used NASA/ESA's Hubble Space Telescope to photograph the asteroid as it shredded when nearing the sun. "Seeing this rock fall apart before our eyes is pretty amazing," David Jewitt, a professor in the UCLA Department of Earth,...

Large Asteroid Set To Pass Between Earth And Moon
2014-03-04 14:50:08

Lee Rannals for redOrbit.com - Your Universe Online An asteroid with a diameter about the size of an 80-story building is sweeping by Earth and the moon on Wednesday. Asteroid 2014 CU13 was first discovered on February 11th by Mt. Lemmon Survey. Since then, the asteroid has been viewed over 230 times, but there still remains a lack of information in trying to pinpoint the space rock’s exact orbit. Slooh will be attempting to offer up a webcast of the asteroid as it makes its...

[ Watch the Video: NASA Spots New Near-Earth Asteroid ] DC Agle, NASA Jet Propulsion Laboratory A collage of radar images of near-Earth asteroid 2006 DP14 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on the night of Feb. 11, 2014. Delay-Doppler radar imaging revealed that the asteroid is about 1,300 feet (400 meters) long, 660 feet (200 meters) wide, and shaped somewhat like a big peanut. The asteroid's period of...

Large Asteroid Passes Within A Few Million Miles Of Earth
2014-02-18 11:05:41

Lee Rannals for redOrbit.com - Your Universe Online The Earth faced a “close-call” on Monday night as near-Earth asteroid 2000 EM26 came within a couple million miles of the planet, nearly a year after the Chelyabinsk meteor exploded over Russia. The asteroid, which was estimated to be about the size of three football fields, whizzed by Earth last night at a distance of 2.1 million miles and traveling at about 27,000 mph. Slooh provided a broadcast of the event so online spectators...

Responding To Potential Asteroid Redirect Mission Targets
2014-02-15 06:26:56

NASA/Jet Propulsion Laboratory One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb. Tracking near-Earth asteroids has been a significant endeavor for NASA and the broader astronomical community, which has discovered 10,713 known near-Earth objects to date. NASA is now pursuing new...

Johann Daniel Titius was born on January 2, 1729 in Konitz, Royal Prussia. He was a professor at Wittenberg. He is most famous for the Titius-Bode law, which helped him find the existence of a minor planet at 2.8 AU from the sun in 1766. The planet was later named Ceres. Titius died in Wittenberg on December 11, 1796. To his honor, the Titius asteroid in 1998 and the Titius lunar crater are named after him.

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Solar System

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
