WASHINGTON, Nov. 6, 2013 /PRNewswire-USNewswire/ -- A team of NASA and international scientists for the first time have gathered a detailed understanding of the effects on Earth from a small asteroid impact. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The unprecedented data obtained as the result of the airburst of a meteoroid over the Russian city of Chelyabinsk on Feb. 15, has revolutionized scientists' understanding of this natural phenomenon. The Chelyabinsk...

Japan's Space Agency Plans To Blast Asteroid With Space Cannon
2013-10-24 09:46:48

Brett Smith for redOrbit.com - Your Universe Online Those of us who were lucky enough to have an Atari gaming console in the 1980s will remember blasting pixelated Asteroids using a triangular spaceship. Now, the Japanese Aerospace Exploration Agency (JAXA) has announced that it plans to send a space cannon out to blast the surface of asteroid 1999JU3 with a metal bullet in 2018. The mission is primarily for research, but could eventually lead to a system capable of defending Earth from...

Using Space Probes To Deflect Asteroids From Earth Trajectories
2013-10-23 14:17:04

[ Watch the Video: Space Probes Could One Day Help Deflect Asteroids ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are conducting experiments to figure out how space probes could be used to deflect potentially hazardous asteroids. Researchers at Fraunhofer Institute for High-Speed Dynamics have begun initial experiments to verify the possibility of deflecting asteroids by impacting them with heavy masses at high speeds. They said the principle behind their research...

2013-10-23 11:08:16

[ Watch the Video: Russia Declares War On Asteroids ] Brett Smith for redOrbit.com - Your Universe Online While some of us may have stopped battling asteroids after putting our Ataris away in the 1980s, the Russian Space Agency appears to be ready to engage in just such a conflict – announcing a few days ago that it would partner with the country’s national academy of sciences over a project to neutralize deadly asteroids that may threaten the Earth. Oleg Ostapenko, head of...

Newly Discovered Asteroid Has Slight Chance Of Impacting Earth
2013-10-18 12:02:43

[ Watch the Video: Earth Receives A Quick Visit From Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. While 4.2 million miles seems far enough away, experts said the rock, known as asteroid 2013 TV135, will have a slight chance of impacting Earth when it returns in 2032. While...

NASA’s Dawn Spacecraft Provides More Information On Asteroid Vesta
2013-09-27 17:17:01

[ Watch the Video: Asteroid Vesta Visited By NASA's Dawn Spacecraft ] Michael Harper for redOrbit.com – Your Universe Online The asteroid Vesta, the second largest in the asteroid belt, has been particularly interesting to astronomers since it was first discovered in 1807. Early observations by the Hubble telescope showed the asteroid was mostly composed like Earth; complete with a crust, mantle and core. It was also discovered that the color and composition of Vesta’s surface...

Amateur Astronomers See Fireballs Collide With Jupiter

[ Watch the Video: Fireballs Collide With Jupiter’s Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online Amateur astronomers observing Jupiter with video cameras for the past three years have observed a trio of collisions between small stellar objects occurring around the planet, according to research presented last week at the European Planetary Science Congress (EPSC 2013) in London. The collisions are similar but smaller in scale than the meteor explosion that...

Researchers Compile Virtual Atlas Of Asteroid Vesta
2013-09-13 08:59:41

redOrbit Staff & Wire Reports - Your Universe Online Astronomy enthusiasts can now take a virtual tour of the asteroid Vesta thanks to an atlas created from images captured during the Dawn Mission’s Low Altitude Mapping Orbit (LAMO), researchers announced Wednesday at the European Planetary Science Congress (EPSC) 2013 in London. The atlas, which was presented by Dr. Thomas Roatsch of the German Aerospace Center (DLR), was comprised of maps created from mosaics of 10,000 images...

Asteroid Don Quixote Is Actually A Comet
2013-09-11 04:25:30

redOrbit Staff & Wire Reports - Your Universe Online When is a near-Earth asteroid not a near-Earth asteroid? When an international team of researchers discover that the object has been misidentified by the scientific community for the past three decades, and is actually a comet. The bombshell discovery was the result of an ongoing project headed up by experts from Northern Arizona University (NAU), and was presented this week at the European Planetary Science Congress 2013 in...

NASA Explorer Leaves Retirement Track Space Rocks
2013-08-22 09:47:16

Brett Smith for redOrbit.com - Your Universe Online NASA announced on Wednesday that one member of its fleet will be coming out of retirement to become part of a project that will eventually lead to placing humans on an asteroid. The Wide-field Infrared Survey Explorer (WISE) discovered and categorized thousands of asteroids throughout the solar system before being decommissioned in February 2011. That retirement will end in September when the orbiter reawakens with a new mission – to...

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...
