WASHINGTON, March 10, 2014 /PRNewswire-USNewswire/ -- NASA's Asteroid Data Hunter contest series will offer $35,000 in awards over the next six months to citizen scientists who develop improved
WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces.
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's Hubble Space Telescope to photograph the asteroid as it shredded when nearing the sun.
An asteroid with a diameter about the size of an 80-story building is sweeping by Earth and the moon on Wednesday. First discovered on February 11, this asteroid has been viewed over 230 times...
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.
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 slammed into Russia.
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.
In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids.
Astronomers, using the European Southern Observatory’s (ESO) New Technology Telescope (NTT), have discovered that asteroids have a highly varied internal structure.
Scientists from MIT and the Paris Observatory claim that rogue asteroids are more common than thought. A move from the previous thinking that most asteroids were static and remained near the sun.
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...
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...
