Latest Asteroid Stories
A former NASA astronaut, the cofounders of Google, and a well-known Hollywood filmmaker are among those lending their support for a forthcoming startup that will attempt to mine asteroids for metals and other raw materials.
NASA announced a new project on Wednesday that will enlist help from amateur astronomers to discover near-Earth objects (NEOs).
New evidence has come up that supports the idea that comets bombarding Earth billions of years ago carried and deposited the key ingredients for life.
Protecting the Earth from an extinction-threatening asteroid has in the past been left up to Hollywood, which has deployed a barrage of special effects box office blockbusters that have kept deadly space rocks from smashing our planet into oblivion.
NASA said on Wednesday its Dawn spacecraft has revealed new details about the surface of the asteroid Vesta.
When it whizzes past Earth in 2013, a newly discovered asteroid is going to miss our planet – but not by much. The 50 m space rock is expected to come closer than many satellites, highlighting the growing need to keep watch on hazards from above.
Since last July, NASA's Dawn spacecraft has been orbiting the asteroid Vesta, and capturing images and other data that are providing surprising results to the delight and amazement of researchers.
NASA officials have identified a large asteroid that is currently on course to hit Earth in approximately three decades time, leading experts to begin discussing possible ways to change its course, various media outlets reported on Tuesday.
Japanese researchers discovered while studying grains of dust from the Itokawa asteroid that tiny particles of space dust bombard asteroids and give them their shape.
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...
