Фото дня: Our New 10th Planet_


Today's Earth Science Picture of the Day.The DIRAS Observatory Team (New Mexico) has captured the new 10th planet or Kuiper Belt Object (2003 UB313), which was found well beyond the orbit of Pluto. This work was led by Leibrecht Venter, Arnie Rosner and John Chumack. Because this object is so faint, it required a very long exposure using a sensitive Charge-Coupled Device (CCD) to detect. A CCD stores packets of information as electric charges. We measured a magnitude for this object of ~18.9. We're now simply waiting on a final decision from the International Astronomy Union on its name. While it has been claimed to be larger than Pluto and located at twice its distance from the Sun, this is still being determined. Collapse )
