A Day on Venus Is Longer Than Its Year

Venus spins so slowly the year ends first

On one planet next door, you could celebrate New Year before a single day had finished. How slowly must a world turn for that?

You'll find out

  • A race between a day and a year
  • The planet that spins backward
  • Why its sunrises come twice as fast

Why it matters

Days and years feel like fixed facts. Venus shows they are just two motions that happen to line up nicely on Earth.
