Latest Asteroid Stories
The asteroid Vesta, the second largest in the asteroid belt, has been particularly interesting to astronomers since it was first discovered in 1807.
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.
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).
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.
NASA announced its Wide-field Infrared Survey Explorer (WISE) will be coming out of retirement to track near-Earth objects (NEOs).
A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013.
NASA announced yesterday that it will be launching a spacecraft in 2016 with the intent of laying the groundwork for future expeditions to mine asteroids.
A team of astronomers from the University of Anitoquia, Medellin, Colombia, have discovered a graveyard of comets.
NASA Deputy Administrator Lori Garver announced this week that the agency has received more than 400 responses to its request for information on its Asteroid Initiative.
The small celestial bodies orbiting between the sun and Jupiter and Neptune are known as centaurs, and their true identity has been one of the enduring mysteries of astrophysics.
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...
