Nereid

Nereid is any one of the sea nymphs, the 50 daughters of Nereus and Doris.

Discovered in 1949 by Kuiper.

Nereid's orbit is the most highly eccentric of any planet or satellite in the solar system; its distance from Neptune varies from 1,353,600 to 9,623,700 kilometers.

Nereid's odd orbit indicates that it may be a captured asteroid or Kuiper Belt object.
