Latest Asteroid Stories
An eruption of dust around a young solar-analog star discovered using the Spitzer Space Telescope could be the type of massive collision between asteroids that ultimately result in the formation of planets, astronomers report in Thursday’s online edition of the journal Science.
Researchers at the University of Tennessee at Knoxville have made a novel discovery that may potentially protect the world from future collisions with asteroids.
New exhibit explores planetary science through interactive multimedia and hands-on experiences. Newark, NJ (PRWEB) August 13, 2014 What exactly are asteroids,
An investigation of Vesta, a massive asteroid that orbits the Sun between Mars and Jupiter, has revealed that the planet-like body has a thicker crust than previously thought, which calls into question the internal structures of other planets in the Solar System.
Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter.
Planet Mercury has an unusual metal-rich composition which has baffled the scientific community. However, new evidence may have solved this mystery.
In the 2020s, NASA will test new technologies to capture an asteroid and direct it to a stable orbit around the moon. Asteroids are being monitored in search of a candidate for the Asteroid Redirect Mission (ARM).
NASA, astronomers and scientists search the sky continually for near-Earth asteroids. Now, with the launch of Asteroid Zoo, the general public can assist in the search for undiscovered NEAs.
It’s been a busy year around the sun for NASA’s Asteroid Grand Challenge.
WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts
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...
