NASA's Jet Propulsion Laboratory For his work making the solar system's nomads of the night sky -- near-Earth objects, asteroids and comets -- tangible and compelling for millions of people, Donald K. Yeomans, the manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, has received the 2013 Carl Sagan Medal from the American Astronomical Society (AAS). The Sagan Medal recognizes a planetary scientist for excellence in public communication....

Asteroid Surface More Unstable Than Previously Thought
2013-07-05 12:02:49

Lee Rannals for redOrbit.com - Your Universe Online An experiment in microgravity has revealed future missions seeking to land on an asteroid may have to watch out for an avalanche. Researchers discovered the rubble and dust covering asteroids and comets could feel changes between particles over much larger distances than on Earth, making these surfaces much less stable than previously thought. "We see examples of force-chains everywhere. When you pick an orange from a pile in a...

University of Arizona University of Arizona researcher Dolores Hill, co-lead of the OSIRIS-REx Target Asteroids! program, has been recognized as one of 12 White House Champions of Change recipients. Hill and her 11 counterparts were selected from a pool of about 1,000 nominations. The group was honored at a ceremony at the White House, which was attended by representatives of the Obama Administration and other honorees' families, friends and colleagues. "It is such an honor to be...

Hawaiian Telescope Discovers Ten Thousandth Near-Earth Object
2013-06-25 13:56:23

Lee Rannals for redOrbit.com – Your Universe Online NASA said the 10,000th near-Earth object (NEO) has been discovered using the Pan-STARRS-1 telescope in Hawaii. Astronomers spotted asteroid 2013 MZ5 on the night of June 18, marking a significant milestone for the NEO search. The space agency said 90 percent of all NEOs discovered were first detected by NASA-supported surveys. "But there are at least 10 times that many more to be found before we can be assured we will have found...

Asteroid Challenge Issued By NASA
2013-06-19 05:44:49

redOrbit Staff & Wire Reports - Your Universe Online NASA is looking for asteroids, and is seeking help from citizen scientists to locate the dangerous space rocks and reduce the potential threats they may pose to human populations. "NASA already is working to find asteroids that might be a threat to our planet, and while we have found 95 percent of the large asteroids near the Earth's orbit, we need to find all those that might be a threat to Earth," said NASA Deputy Administrator...

Asteroids Found To Have Similar Orbit To Uranus
2013-06-19 04:44:21

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In 2006, Uruguayan astronomer Tabaré Gallardo provided evidence that two asteroids, Crantor and 2000 SN331, had orbital periods similar to that of the planet Uranus — roughly 84 Earth-years. Now, some seven years later, researchers Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, at the Complutense University of Madrid (UCM), have confirmed that not two, but three large asteroids...

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...
