|Solar System Scratchpad|
Second Inner Oort Belt object discovered. Likely a dwarf planet with half the size of Sedna. Its perihelion is only the second found to be far enough so as not to be affected by Neptune, and is thus "detached" from the main part of the Solar System. Its argument of perihelion is near Sedna's, which could be signs of herding from a more distant super-Earth planet. Its origin could be a planet that was first scattered from the solar system, and then its perihelion reduced by other stars in the Sun's birth cluster. It would then have been unaffected by the planets or passing nearby stars, and thus remained stable over billions of years. Nicknamed "Biden" after the "VP" portion of its designation. Its surface is likely pink in color, indicative of forming in the gas giant region of space rather than the Kuiper Belt.
