Scientists discover oldest known asteroids in solar system

Washington, March 21 : A team of scientists has identified three asteroids that appear to be among our Solar System's oldest objects.

Astronomers Find Oldest Known Asteroids

Researchers from the University of Maryland have recently discovered three asteroids that appear to be roughly 4.55 billion years old, dating back to the formation of the Solar System. The scientists say that the asteroids have survived relatively unchanged since that time, and make good candidates for future space missions. "'The fall of the Allende meteorite in 1969 initiated a revolution in the study of the early Solar System,' said Tim McCoy, curator of the national meteorite collection at the Smithsonian's National Museum of Natural History. 'I find it amazing that it took us nearly 40 years to collect spectra of these [CAI-rich] objects and that those spectra would now initiate another revolution, pointing us to the asteroids that record this earliest stage in the history of our Solar System.

Need an Idea for a Solar System School Project? Build a Scale Model of the Solar System

Everyone seemed to enjoy the answer to my daughter's question, "what's the biggest star?", so I thought I'd give you another insight into space science at the Cain household. A couple of months ago, we built a scaled map of the Solar System. I thought I'd share my process and resources with you, and throw in a few cute pictures of the kids. So come on, let's build a solar system in your neighborhood.

Astronomers Locate Solar System Very Similar To Our Own

Smivs writes "Astronomers from St Andrews University in the UK have discovered a planetary system which looks much like our own. Dr Martin Dominik told BBC news: 'We found a system with two planets that take the roles of Jupiter and Saturn in our Solar System. These two planets have a similar mass ratio and similar orbital radius and a similar orbital period. The newfound planetary system, which orbits the star OGLE-2006-BLG-109L, is more compact than our own and is about five thousand light-years away. The OGLE planets were found using a technique called gravitational micro-lensing, in which light from the faraway planets is bent and magnified by the gravity of a foreground object, in this case a another star.'"
