  • The Dark Energy Survey Begins to Reveal Previously Unknown Trans-Neptunian Objects

    While asteroids residing in the inner solar system will pass quickly through such small fields, trans-Neptunian objects (TNOs) orbit the Sun much more slowly. For example, Pluto, at an approximate distance of 40 A.U. from the Sun, along with the object Eris, presently the largest of the TNOs, has an apparent motion of about 27 arc seconds per day – although for a half year, the Earth’s orbital motion slows and retrogrades Pluto’s apparent motion. The 27 arc seconds is approximately 1/60th the width of a full Moon. So, from one night to the next, TNOs can travel as much...
  • Astronomy Picture of the Day -- Two Rings for Asteroid Chariklo

    Explanation: Asteroids can have rings. In a surprising discovery announced two weeks ago, the distant asteroid 10199 Chariklo was found to have at least two orbiting rings. Chariklo's diameter of about 250 kilometers makes it the largest of the measured centaur asteroids, but now the smallest known object to have rings. The centaur-class minor planet orbits the Sun between Saturn and Uranus. The above video gives an artist's illustration of how the rings were discovered. As Chariklo passed in 2013 in front of a faint star, unexpected but symmetric dips in the brightness of the star revealed the rings. Planetary...
  • Asteroid Found with Rings! First-of-Its-Kind Discovery Stuns Astronomers

    Scientists have made a stunning discovery in the outer realm of the solar system — an asteroid with its own set of rings that orbits the sun between Saturn and Uranus. The space rock is the first non-planetary object ever found to have its own ring system, researchers say. The pair of space rock rings encircle the asteroid Chariklo. They were most likely formed after a collision scattered debris around the asteroid, according to a new study unveiled today (March 27). The asteroid rings also suggests the presence of a still-undiscovered moon around Chariklo that's keeping them stable, researchers said....
  • NRO Spacecraft In Wrong Orbit

    Two top secret National Reconnaissance Office (NRO) ocean surveillance spacecraft were fired into the wrong orbit June 15 when the 200-foot-tall Atlas V rocket they were riding on stopped firing too early in space following launch from Cape Canaveral, Fla. The top secret satellites separated safely from the malfunctioning booster, however, and have enough rocket propellant to continue their mission, an official said on background. The U.S. Air Force, which managed the Atlas V launch, and the NRO have begun an official investigation into the launch and malfunction. The $83 million Atlas V used in the launch is a model...

    “Ancient Russian Centaur” Found In Novgorod 17.08.2006 During archeological diggings in Velikiy Novgorod Russian scientists have found a figure they named "ancient Russian centaur". The figure was found in layers dated back to the end of XI century in the Troitsky dig near the Novgorod Kremlin. Unknown craftsman had cut a wooden bearded man with a hat on his head and a bow behind his back. The figure has hooves instead of feet and is covered with a golden coating. It is broken in that very part, where human body transforms to the body of a horse. The other part...

The third possibility is that the region beyond was brushed clear by the gravity of Planet X... the KBO orbits they have investigated so far fit in best with the influence of a Planet X.
