Lee Rannals for redOrbit.com - Your Universe Online Mars may be helping to shape the surface of some near-Earth asteroids, according to a new study published in the journal Icarus. Richard Binzel, a professor of planetary sciences at MIT, found in 2010 that asteroids that venture outside of the main belt in our solar system could be experiencing “asteroid quakes” as they come too close to Earth’s gravity. These quakes shift surface grains, exposing fresh grains underneath, which helps...

Six-Tailed Asteroid Caught By NASA's Hubble Space Telescope
2013-11-07 15:50:06

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the NASA Hubble Space Telescope have witnessed an asteroid with six comet-like tails of dust. NASA said the asteroid, designated P/2013 P5, resembles a rotating lawn sprinkler with the dust radiating from it like water being whipped around a yard. P/2013 P5, located in our Solar System’s asteroid belt, is puzzling astronomers with its unusual appearance. "We were literally dumbfounded when we saw it," said lead...

Dawn Mission Data Offers New Evidence On Vesta Asteroid's History
2013-11-07 15:32:00

Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the journal Nature rewrites the history of the giant asteroid Vesta, which was recently visited by NASA’s Dawn mission. It was during the Dawn mission that the spacecraft used its visible and infrared mapping spectrometer instrument to map out the surface of the asteroid, leading scientists to the belief that Vesta’s formation followed the script that rocky planets followed, where the mineral olivine should...

Japan's Space Agency Plans To Blast Asteroid With Space Cannon

Brett Smith for redOrbit.com - Your Universe Online Those of us who were lucky enough to have an Atari gaming console in the 1980s will remember blasting pixelated Asteroids using a triangular spaceship. Now, the Japanese Aerospace Exploration Agency (JAXA) has announced that it plans to send a space cannon out to blast the surface of asteroid 1999JU3 with a metal bullet in 2018. The mission is primarily for research, but could eventually lead to a system capable of defending Earth from...

Using Space Probes To Deflect Asteroids From Earth Trajectories
2013-10-23 14:17:04

[ Watch the Video: Space Probes Could One Day Help Deflect Asteroids ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are conducting experiments to figure out how space probes could be used to deflect potentially hazardous asteroids. Researchers at Fraunhofer Institute for High-Speed Dynamics have begun initial experiments to verify the possibility of deflecting asteroids by impacting them with heavy masses at high speeds. They said the principle behind their research...

Russia's Space Program Has Declared War On Menacing Asteroids

[ Watch the Video: Russia Declares War On Asteroids ] Brett Smith for redOrbit.com - Your Universe Online While some of us may have stopped battling asteroids after putting our Ataris away in the 1980s, the Russian Space Agency appears to be ready to engage in just such a conflict – announcing a few days ago that it would partner with the country’s national academy of sciences over a project to neutralize deadly asteroids that may threaten the Earth. Oleg Ostapenko, head of...

Newly Discovered Asteroid Has Slight Chance Of Impacting Earth
2013-10-18 12:02:43

[ Watch the Video: Earth Receives A Quick Visit From Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. While 4.2 million miles seems far enough away, experts said the rock, known as asteroid 2013 TV135, will have a slight chance of impacting Earth when it returns in 2032. While...

NASA’s Dawn Spacecraft Provides More Information On Asteroid Vesta
2013-09-27 17:17:01

[ Watch the Video: Asteroid Vesta Visited By NASA's Dawn Spacecraft ] Michael Harper for redOrbit.com – Your Universe Online The asteroid Vesta, the second largest in the asteroid belt, has been particularly interesting to astronomers since it was first discovered in 1807. Early observations by the Hubble telescope showed the asteroid was mostly composed like Earth; complete with a crust, mantle and core. It was also discovered that the color and composition of Vesta’s surface...

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...

Solar System

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...
