Nereid ("NEER ee ed") is the outermost of Neptune's known satellites and the third largest, with a diameter of 340 km. Its orbit averages 5,513,400 km in diameter, but is highly eccentric? and varies from 1,353,600 to 9,623,700 kilometers. This is the most highly eccentric orbit of any known planet or satellite in the solar system. This unusual orbit suggests that it may be a captured asteroid or Kuiper belt object, or possibly that it was perturbed during the capture of Neptune's largest moon Triton. Very little else is known of Nereid. |
