Latest Asteroid Stories
An asteroid about the same size as the one that exploded over Russia's Ural Mountains last month will be making a close, but safe pass by Earth tonight.
In the wake of the recent meteor explosion above Russia, the European Space Agency has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA).
Astronomers say they have discovered the reason behind the strange scene when finding an asteroid with a tail.
On February 15, asteroid 2012 DA14 passed extraordinarily close to the earth.
A pair of California scientists unveiled a proposal this week for a system that could eliminate threatening asteroids or meteors, just as a meteorite explodes over Russia and an asteroid grazes past Earth within a 24-hour span.
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.
Deep Space Industries announced this week that DA14, the asteroid making a close approach to Earth this week, could be worth up to $195 billion, assuming it were in a different orbit.
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 nearby cosmic neighbor.
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.
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...
