Asteroid Passing Earth Tonight, Similar In Size To Last Month's Russian Meteor
2013-03-04 15:17:42

Lee Rannals for redOrbit.com — Your Universe Online An asteroid about the same size as the meteor that exploded over Russia's Ural Mountains last month will be making a close, but safe pass by Earth tonight. Asteroid 2013 EC will be passing by Earth about 246,000 miles away, about 20 times farther out than Asteroid 2012 DA14 that passed by February 15. The asteroid was discovered on Saturday by astronomers at the Mt. Lemmon Observatory in Arizona. Asteroid 2013 EC is between...

Asteroid Mission Targets Didymos In 2022
2013-02-23 05:53:38

redOrbit Staff & Wire Reports - Your Universe Online In the wake of the recent meteor explosion above Russia, the European Space Agency (ESA) has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA). The AIDA mission, which is a joint project headed up by European and American astronomers, will attempt to intercept asteroid Didymos, which the ESA says is a “binary,” featuring two asteroids — one approximately 800...

Astronomers Gain Asteroid Trail Understanding
2013-02-21 20:43:10

Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in The Astrophysical Journal Letters say they have discovered the reason behind the strange scene when finding an asteroid with a tail. Just ten asteroids to date have been observed to have displayed a tail, similar to a comet, and one of these objects, P/2012 F5, was discovered in March 2012 from the Mount Lemmon Observatory in Arizona. These asteroids are also known as MBCs. Spanish astrophysicists from...

On February 15, asteroid 2012 DA14 passed extraordinarily close to the earth. Unlike the unexpected asteroid collision over Russia that day, this encounter never presented any danger but astronomers were eager to observe the event. An international team led by Nicholas Moskovitz (MIT) observed the asteroid with a number of telescopes, including the 2.1m telescope at Kitt Peak National Observatory: the accompanying video shows the asteroid as it was leaving the vicinity of the earth. As Dr....

Scientists Propose System For Eliminating Threat Of Asteroids, Meteors
2013-02-15 13:01:40

Brett Smith for redOrbit.com - Your Universe Online A pair of California scientists unveiled a proposal this week for a system that could eliminate threatening asteroids or meteors, just as a meteor explodes over Russia and an asteroid grazes past Earth within a 24-hour span. Several online videos showing a meteorite streaking, then exploding over Russia, and reports describing the asteroid 2012 DA14 serve as timely reminders of just how crucial the system, dubbed DE-STAR, could be....

Planetary Resources To Join The Hunt For Asteroids
2013-02-15 05:03:47

[ Watch the Video: Asteroid 2012 DA14 To Whiz Past Earth Safely ] Lee Rannals for redOrbit.com - Your Universe Online Planetary Resources, a company aimed at mining asteroids, says that its Arkyd-100 Series of spacecraft will be assisting in the detection and characterization of potentially hazardous asteroids near Earth. About 610,000 asteroids are being tracked in the Solar System currently, which is a number that represents less than one percent of the estimated objects that orbit...

Billion Dollar Asteroid Making Close Approach To Earth
2013-02-14 10:55:10

Lee Rannals for redOrbit.com - Your Universe Online The idea to start attempting to mine asteroids has been floating around recently, but questions remain as to whether or not such a business endeavor would even be lucrative. Now, however, Deep Space Industries (DSI) claims that one particular asteroid could be worth as much as $195 billion in metals and propellant. Deep Space Industries announced this week that DA14, the asteroid making a close approach to Earth this week, could be...

Asteroid Spin May Reveal Clues About Its Future Orbital Path
2013-02-12 11:46:49

April Flowers for redOrbit.com - Your Universe Online On February 15, astronomers will have an exciting opportunity with a record-setting close approach of an asteroid.  The research team, using the National Radio Astronomy Observatory (NRAO) and NASA telescopes, will gain a key clue that will help predict the future of this natural cosmic orbiter. Discovered just a year ago, the 150-foot-wide asteroid, called 2012 DA14, will pass only 17,200 miles from the Earth on Friday, which...

'Near-miss' Asteroid Being Tracked By Hertfordshire Astronomers
2013-02-12 11:19:35

Alpha Galileo Foundation An asteroid the size of a small office block is due to pass by Earth on Friday 15 February in one of the closest ℠near-misses´ in recent history. Although there is no chance of the asteroid hitting Earth, the huge rock is being closely monitored by astronomers at the University of Hertfordshire´s Bayfordbury Observatory, as part of an on-going program to monitor ℠Near Earth Objects´ (NEO). Weighing 130,000 tonnes and traveling at over...

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
2012-10-22 06:09:41

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...
