Seasons on Other Planets.
Each planet in the solar system has seasons. Earth has four seasons. Most planets do, too. They are called winter, spring, summer and fall. What is the same about the seasons on other planets? Only their names. The seasons are different on each planet. On Venus, seasons are short. On Saturn, a season can last for seven years. And on Mercury, you can't even tell when one season ends and the next one begins. Pluto is too far away. We don't know about its seasons.

This chart shows how long the seasons last. Imagine living on Neptune. How old would you be on your next summer vacation?

PLANET LENGTH OF SEASON
Venus 55-58 days
Earth 90-93 days
Mars 7 months
Jupiter 3 years
Saturn About 7 years
