From Fairfield, it will be visible all night. It will become visible around 20:43 (EDT) as the dusk sky fades, 23° above your eastern horizon. It will then reach its highest point in the sky at 01:36, 65° above your southern horizon. It will be lost to dawn twilight around 05:02, 39° above your western horizon.
136108 Haumea opposite the Sun
This optimal positioning occurs when 136108 Haumea is almost directly opposite the Sun in the sky. Since the Sun reaches its greatest distance below the horizon at midnight, the point opposite to it is highest in the sky at the same time.
At around the same time that 136108 Haumea passes opposition, it also makes its closest approach to the Earth – termed its perigee – making it appear at its brightest and largest.
This happens because when 136108 Haumea lies opposite the Sun in the sky, the solar system is lined up so that 136108 Haumea, the Earth and the Sun form a straight line with the Earth in the middle, on the same side of the Sun as 136108 Haumea.
In practice, however, 136108 Haumea orbits much further out in the solar system than the Earth – at an average distance from the Sun of 43.21 times that of the Earth, and so its angular size does not vary much as it cycles between opposition and solar conjunction.
On this occasion, 136108 Haumea will lie at a distance of 49.45 AU, and reach a peak brightness of magnitude 17.3. Even at its closest approach to the Earth, however, 136108 Haumea is so distant from the Earth that it is not possible to distinguish it as more than a star-like point of light.
136108 Haumea in coming weeks
Over the weeks following its opposition, 136108 Haumea will reach its highest point in the sky four minutes earlier each night, gradually receding from the pre-dawn morning sky while remaining visible in the evening sky for a few months.
The position of 136108 Haumea at the moment it passes opposition will be:

The circumstances of this event were computed using the DE405 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.
