JAXA Set To Launch Hayabusa 2 In 2014
2013-04-01 20:59:22

Lee Rannals for redOrbit.com — Your Universe Online The Japan Aerospace Exploration Agency's (JAXA) next asteroid exploring spacecraft, Hayabusa 2, will be launching in 2014 on a mission to bring back sand from an asteroid. Hayabusa 2 will travel through space for four years before arriving at asteroid 1999 JU3, and will not be returning to Earth until 2020. Once the spacecraft reaches its target, it will fire off fingertip-sized bullets into the surface of the asteroid at about...

NASA Scientists Find Striking Similarity Between Moon And Asteroids
2013-03-26 07:24:40

Lawrence LeBlond for redOrbit.com - Your Universe Online 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 Moffett Field, California-based NLSI found that the same population of high-speed projectiles that bombarded the Moon four billion years ago, also impacted the giant...

NASA Warns Lawmakers More Funding Needed To Protect Earth From Doomsday Asteroids
2013-03-20 09:23:02

Lawrence LeBlond for redOrbit.com - Your Universe Online 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.” That is unless, of course, the government can do more now to ensure...

Asteroid 2013 ET Captured By Deep Space Network
2013-03-20 08:50:01

April Flowers for redOrbit.com - Your Universe Online 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. At the time the images were captured, the asteroid was about 693,000 miles from Earth, or approximately 2.9 lunar distances. The asteroid is irregularly shaped and at least 130 feet wide according to the radar imagery. The scientific team, led by Marina Brozovic and Lance...

Passing Asteroid Will Be Broadcast Live By SLOOH Today
2013-03-09 12:02:37

Lee Rannals for redOrbit.com — Your Universe Online An asteroid about the size of a city block will be making its way past Earth later today, and Slooh plans on giving the world access to its tools to view the near-Earth object (NEO). Slooh, a leader in live, celestial event programming, said in a statement earlier this week that it will be broadcasting the asteroid 2013 ET on Saturday (Mar 9) as the it passes by Earth at about 2.5 times the Moon's distance from us. 2013 ET was...

Asteroid Intercept System
2013-03-08 04:39:48

Lee Rannals for redOrbit.com - Your Universe Online 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. However, Iowa State engineers say they are coming up with a few ideas to help save our planet from a repeat of the asteroid-impact that led to the dinosaur annihilation. Bong Wie and colleagues from Iowa State will be presenting a paper as part of NASA's...

The Hunt For Near-Earth Asteroids Heats Up After 2012 EC Passes Earth
2013-03-05 06:16:21

Lawrence LeBlond for redOrbit.com - Your Universe Online 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. The asteroid, 2012 EC, was detected by Arizona´s Mt. Lemmon Observatory and astronomers calculated its trajectory, confirming the object would...

Asteroid Passing Earth Tonight, Similar In Size To Last Month's Russian Meteor
2013-03-04 15:17:42

Lee Rannals for redOrbit.com — Your Universe Online An asteroid about the same size as the meteor that exploded over Russia's Ural Mountains last month will be making a close, but safe pass by Earth tonight. Asteroid 2013 EC will be passing by Earth about 246,000 miles away, about 20 times farther out than Asteroid 2012 DA14 that passed by February 15. The asteroid was discovered on Saturday by astronomers at the Mt. Lemmon Observatory in Arizona. Asteroid 2013 EC is between...

Asteroid Mission Targets Didymos In 2022
2013-02-23 05:53:38

redOrbit Staff & Wire Reports - Your Universe Online In the wake of the recent meteor explosion above Russia, the European Space Agency (ESA) has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA). The AIDA mission, which is a joint project headed up by European and American astronomers, will attempt to intercept asteroid Didymos, which the ESA says is a “binary,” featuring two asteroids — one approximately 800...

Astronomers Gain Asteroid Trail Understanding
2013-02-21 20:43:10

Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in The Astrophysical Journal Letters say they have discovered the reason behind the strange scene when finding an asteroid with a tail. Just ten asteroids to date have been observed to have displayed a tail, similar to a comet, and one of these objects, P/2012 F5, was discovered in March 2012 from the Mount Lemmon Observatory in Arizona. These asteroids are also known as MBCs. Spanish astrophysicists from...

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
2012-10-22 06:09:41

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...
