From our vantage point on the Earth, 134340 Pluto will appear very close to the Sun in the sky as it passes around the far side of the solar system from the Earth.
At closest approach, 134340 Pluto and the Sun will appear at a separation of only 1°34', making 134340 Pluto 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 34.00 AU – since the two planets will lie on opposite sides of the solar system.
If 134340 Pluto could be observed at this time, it would appear at its smallest and faintest on account of its large distance. It would measure 0.0 arcsec in diameter.
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.

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