Dwarf planet Pluto at Opposition

- Pluto reaches opposition on Wednesday 26 August when Earth passes directly between the Sun and Pluto.
o - Although Pluto is still extremely faint, opposition is the best time of the year to observe it because:
o
– it rises at sunset and sets at sunrise, so it is visible all night.
– it is at its brightest for the year, around magnitude +14.3 to +14.5, though still far too faint for small telescope.
