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...

OSIRIS-Rex To Study Asteroid Yarkovsky Effect
2013-02-08 18:46:31

Lee Rannals for redOrbit.com — Your Universe Online NASA will be launching a new mission in 2016 to help estimate what kind of impact an asteroid would make if it struck Earth. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, and Regolith Explorer) mission will travel to a potentially hazardous asteroid (PHA), and make measurements of the Yarkovsky effect. This effect is a push on an asteroid that happens when it is warmed up by the sun and...

Real-Time Video Of Asteroid 2012 DA14 Offered By Clay Center Observatory
2013-02-06 10:22:22

Clay Center Observatory When a small asteroid brushes within 18,000 miles of Earth in 10 days, the news media and public will be able to watch the celestial near-miss as it happens. On Friday, February 15th, weather permitting, real-time high-definition video from the Clay Center Observatory will be available from 6 p.m. EST until 4 a.m. the next morning (3 p.m. to 1 a.m. PST). The video feed can be freely accessed worldwide via the observatory´s Ustream channel. A countdown...

Small Asteroid Will Pass By Earth Safely
2013-02-04 08:30:02

NASA's Jet Propulsion Laboratory The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so close that it will pass inside the ring of geosynchronous weather and communications satellites. NASA's Near-Earth Object Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique...

Large Asteroid Will Make Earth Flyby Next Month
2013-01-29 12:55:40

[Watch Video: Record-Setting Asteroid Flyby] Lee Rannals for redOrbit.com — Your Universe Online A record-setting asteroid about the size of half a football field will be making a close flyby to Earth just after Valentine's Day. Although there is no danger of a collision, the asteroid, 2012 DA14, will still be making a record-setting close approach, according to NASA. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth," Don...

Apophis Won’t Hit Earth In 2036
2013-01-13 08:33:31

redOrbit Staff & Wire Reports — Your Universe Online There is a less than one-in-a-million chance that a massive asteroid, approximately as wide as three American football fields, will collide with Earth in 2036, NASA officials confirmed on Wednesday. According to MSNBC.com´s Alan Boyle, the “all-clear” was sounded by the US space agency after asteroid Apophis came within nine million miles of our planet. In fact, officials with NASA´s...

Herschel Observed Asteroid Apophis Over The Weekend
2013-01-09 14:28:25

ESA ESA´s Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective. Catalogued as asteroid (99942) Apophis (previously 2004 MN4), it is often nicknamed ℠the doomsday asteroid´ in popular media, after initial observations made after its discovery in 2004 gave it a 2.7% chance of striking Earth in April 2029. With additional data, however,...

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...
