Answer: True

As far as is known in the early twenty-first century, only Pluto, Venus and Uranus have retrograde rotation, which means the sun rises in the west and sets in the east. Pluto also rotates horizontally, on its orbital plane, so its seasonal variation is extreme; at its solstices, one-fourth of its surface is continuous day, whereas another fourth is continuous night.
