what planet rotates the slowest?

Venus is the planet that rotates the slowest, taking about 243 Earth days to complete a single turn on its axis, which is even longer than its year.

Quick Scoop

• Slowest spinner: Venus has the slowest rotation of any planet in our solar system.

• Ultra-long “day”: One Venus day (one full spin) lasts about 243 Earth days, while its year (one orbit around the Sun) is about 225 Earth days.

• Weird direction: Venus also rotates in the opposite direction to most planets (retrograde rotation), so on Venus the Sun would appear to rise in the west and set in the east.

In practical terms, if you stood on Venus (ignoring the extreme heat and pressure), you’d wait longer than an entire Venusian year just to see one full day–night cycle.
