Latest Asteroid Stories
Jovian asteroids that orbit the Sun on the same trajectory as the gas giant Jupiter have been studied more closely by scientists using NASA’s Wide-field Infrared Survey Explorer (WISE).
The European Space Agency reports that it has rediscovered an asteroid that was once lost through the agency's space hazards program.
Scientists have determined that the second-most-massive asteroid in the solar system may have once had an active dynamo.
The cooperative space project Hayabasa set out to collect the very first samples from the surface of a near-earth asteroid, Itokawa. Scientists believe that the work will offer insight into the early history of our Solar System and the formation of the planets more than 4.5 billion years ago.
ESA's Herschel Space Observatory has discovered pristine material that matches comets in our own Solar System in a dust belt around the young star Beta Pictoris.
Astronomers suggest that water may have been delivered to Vesta through a build-up of small particles during an epoch when the Solar System was rich in dust.
According to findings reported in the journal Science, NASA's Dawn spacecraft has revealed signs of hydrated minerals on the giant asteroid Vesta.
Momentum Grows for First Private Deep Space Mission to Map the Inner Solar System and Track Asteroids Posing Threats to Earth
As NASA's Dawn mission spacecraft speeds away from the giant asteroid Vesta, mission control has released two parting views using images that were among the last taken by Dawn.
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...
