NASA Space Place: What Is a Leap Year?
It takes approximately 365.25 days for Earth to orbit the Sun — a solar year.
We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
Launched in 1998, NASA Space Place’s mission is to inspire and enrich upper-elementary-aged kids’ learning of space and Earth science online through fun games, hands-on activities, informative articles and engaging short videos.
With material in both English and Spanish and resources for parents and teachers, NASA Space Place has something for everyone.
