Trivia

What it actually is

  • Its orbit family. A trans-Neptunian object from the Kuiper Belt, out where the Sun is little more than the brightest star in a very dark sky.
  • One lap. A single orbit around the Sun takes it about 221 years.
  • How far it roams. Its orbit swings between 31.64 and 41.38 AU from the Sun.

Sense of scale

  • Sense of scale. In everyday terms it is about 7.6× the length of Manhattan island.
  • Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 12.9 days.

By the numbers

  • Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 164 km across.

What's in a name

  • Designation. Known only by its catalogue designation — no name yet.
