Latest Asteroid Stories
Water vapor has been discovered around the dwarf planet Ceres thanks to new data from the Herschel Space Observatory.
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has made its first discovery since coming out of hibernation last year: a never-before-seen asteroid dubbed 2013 YP139.
An undergraduate astronomy class for non-astronomy majors at the University of Maryland has made a rare discovery that was completely overlooked by professional scientists: a pair of asteroids that orbit each other.
According to NASA, the first asteroid of the 2014 season was discovered by Catalina Sky Survey, a NASA-sponsored observatory near Tucson, Arizona. It has been designated as 2014 AA and was viewed moving across the sky early Wednesday morning, January 1, 2014.
NEOWISE has returned to service, and has sent its first set of test images back to Earth in preparation for a renewed mission.
Some beauty is revealed only at a second glance. When viewed with the human eye, the giant asteroid Vesta, which was the object of scrutiny by the Dawn spacecraft from 2011 to 2012, is quite unspectacular color-wise.
Jupiter’s icy moon Europa appears to have clay-type minerals on its surface, according to new data from NASA’s Galileo mission.
NASA announced that it had started the countdown for OSIRIS-REx, the space agency’s mission to collect a physical sample from a distant asteroid.
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...
