134340 Pluto 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, 134340 Pluto will appear at a separation of only 0°07' from the Sun, making it totally unobservable for several weeks while it is lost in the Sun's glare.

At around the same time, 134340 Pluto will also be at its most distant from the Earth – receding to a distance of 34.71 AU – since the two planets will lie on opposite sides of the solar system.

Over following weeks and months, 134340 Pluto 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 134340 Pluto across the sky in 2019 can be found here, and a chart of its rising and setting times here.

The position of 134340 Pluto at the moment it passes solar conjunction will be:

Object Right Ascension Declination Constellation Angular Size
134340 Pluto 19h29m40s 21°57'S Sagittarius 0.0"
Sun 19h29m 21°50'S Sagittarius 32'31"

The coordinates above are given in J2000.0.
