136108 Haumea's 282.0-year orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 51.49 AU.

Unlike most of the planets, which follow almost exactly circular orbits around the Sun which only vary in their distance from the Sun by a few percent, 136108 Haumea has a significantly elliptical orbit. Its distance from the Sun varies between 34.59 AU and 51.42 AU – a variation of over 48% – meaning that it receives 54% less heat and light from the Sun at aphelion as compared to perihelion.

Finding 136108 Haumea

136108 Haumea's distance from the Sun doesn't affect its appearance. From South El Monte, at the moment of aphelion it will be visible in the evening sky, becoming accessible around 20:26 (PDT), 43° above your eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 23:53, 79° above your southern horizon. It will continue to be observable until around 05:06, when it sinks below 21° above your western horizon.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
