Objects: 136199 Eris

136199 Eris 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, 136199 Eris will appear at a separation of only 9° from the Sun, making it totally unobservable for several weeks while it is lost in the Sun's glare.

At around the same time, 136199 Eris will also be at its most distant from the Earth – receding to a distance of 96.12 AU – since the two planets will lie on opposite sides of the solar system.

Over following weeks and months, 136199 Eris 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. A chart of the path of 136199 Eris across the sky in 2030 can be found here, and a chart of its rising and setting times here.

The position of 136199 Eris at the moment it passes solar conjunction will be:

Object Right Ascension Declination Constellation Angular Size
136199 Eris 01h49m30s 1°00'N Cetus 0.0"
Sun 01h35m 9°57'N Pisces 31'52"

The coordinates above are given in J2000.0.
