sentences:  The results supersedes a previous study that gave a much larger diameter of 350 kilometers with a lower albedo of 0.03.According to Michael Brown, it is "probably not" a dwarf planet candidate, due to its relatively small diameter estimated at 158 kilometers.The "Collaborative Asteroid Lightcurve Link" assumes an albedo of 0.10 and derives a diameter of 139.81 kilometers based on an absolute magnitude of 7.39.
  
   was part of a rotational lightcurve study which was published in the journal "Nature" in 1999.
