Latest Asteroid Stories
Scientists at the University of Arizona welcome President Barack Obama's NASA budget proposal, rolled out today, and specifically its focus on gaining a better understanding of asteroids that could potentially harm Earth.
The European Space Agency's Herschel space observatory has snapped images of a dust belt orbiting a subgiant star that hosts a planetary system.
The Japan Aerospace Exploration Agency's next asteroid exploring spacecraft, Hayabusa 2, will be launching in 2014 on a mission to bring back sand from an asteroid.
Scientists from NASA’s Lunar Science Institute (NLSI), along with researchers from abroad, have discovered that Earth’s own natural satellite shares a striking similarity with Vesta, and perhaps other large asteroids roaming around the Solar System.
The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.”
On March 10, 2013, NASA scientists obtained a sequence of radar images of asteroid 2013 ET using the 230-foot Deep Space Network antenna at Goldstone, California.
An asteroid about the size of a city block will be making its way past Earth this afternoon, and Slooh plans on giving the world access to its tools to view the near-Earth object (NEO).
The combination of new technology, a growing interest in astronomy, and more media hype has led to an even bigger fear of "what if" scenarios for potentially hazardous asteroids.
An asteroid that was only discovered Saturday (Mar. 2) has made a run by Earth in the early hours of March 5, some 250,000 miles away. While the asteroid is being associated with last month’s Russian meteor in respect to its mass, the two bodies are not linked in any other way.
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...
