Trivia Question 4/19/12 – A Day on Venus

The Solar SystemWe are accustomed to thinking of a day as 24 hours. However, that definition is a narrow one that only applies to our own planet. A day is the length of time it takes for a planet to complete one rotation on its axis – 360°. On Earth, that’s 24 hours.  But, since all of the planets rotate at different speeds, the length of a day on each one differs.

The planet with the longest day is Venus.


In Earth time, how long is a day on Venus?


243 days.


Venus is the second planet from the Sun, and is named after Venus, the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, bright enough to cast shadows. Most planets rotate counter-clockwise, but Venus rotates clockwise. Venus has the longest day of any planet in our Solar System. A day on Venus is 243 Earth days. Venus’ day is actually longer than its year. It only takes 224.7 Earth days for the planet to orbit the Sun.
