Latest Asteroid Stories
WASHINGTON, March 26, 2015 /PRNewswire-USNewswire/ -- Millions of images of celestial objects, including asteroids, observed by NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE)
A rare class of so-called “active asteroids” that appear to leave behind a tail of dust and debris similar to that of a comet are travelling so fast that they are essentially making themselves blow up, according to research published Friday in Astrophysical Journal Letters.
One of the biggest mysteries of space this year might have just been solved.
A software application based on an algorithm created by a NASA challenge has the potential to increase the number of new asteroid discoveries by amateur astronomers.
There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser extent, rings of gas and dust also encircle Jupiter, Uranus, and Neptune. The fifth member of this haloed group is Chariklo, one of a class of minor planets called centaurs: small, rocky bodies that possess qualities of both asteroids and comets.

WASHINGTON, March 6, 2015 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet.
After a journey of more than 7 1/2 years, NASA’s Dawn spacecraft was expected to enter orbit around Ceres, the largest object in the asteroid belt between Mars and Jupiter, this morning.
WASHINGTON, March 2, 2015 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft has returned new images captured on approach to its historic orbit insertion at the dwarf planet Ceres.
A bright spot previously detected on the dwarf planet Ceres appears to have a somewhat dimmer companion, and NASA remain unable to explain exactly what these unusual lights are.
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...
