136108 Haumea will pass close to the Sun in the sky as its orbit carries it around the far side of the solar system from the Earth.
At closest approach, 136108 Haumea will appear at a separation of only 27° from the Sun, making it totally unobservable for several weeks while it is lost in the Sun's glare.
At around the same time, 136108 Haumea will also be at its most distant from the Earth – receding to a distance of 50.72 AU – since the two planets will lie on opposite sides of the solar system.
Over following weeks and months, 136108 Haumea will re-emerge to the west of the Sun, gradually becoming visible for ever-longer periods in the pre-dawn sky. After around six months, it will reach opposition, when it will be visible for virtually the whole night.
