Cometary Origins For Most Centaurs: WISE
2013-07-26 04:44:52

April Flowers for redOrbit.com - Your Universe Online The small celestial bodies orbiting between the sun and Jupiter and Neptune are known as centaurs, and their true identity has been one of the enduring mysteries of astrophysics. Previously, scientists have questioned, are they asteroids or comets? A new study, published in the Astrophysical Journal, using observations from NASA's Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. Astronomers have been unsure...

Asteroids Found To Have Similar Orbit To Uranus
2013-06-19 04:44:21

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In 2006, Uruguayan astronomer Tabaré Gallardo provided evidence that two asteroids, Crantor and 2000 SN331, had orbital periods similar to that of the planet Uranus — roughly 84 Earth-years. Now, some seven years later, researchers Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, at the Complutense University of Madrid (UCM), have confirmed that not two, but three large asteroids...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

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...
