Earth revolves around the sun once every 365 days. A revolution is the time it takes an object to complete one orbit, while rotation refers to an object spinning on its axis. The length of a year is different for each planet depending on how far it is from the sun, with closer planets like Mercury having shorter years than Earth and more distant planets like Neptune having longer years.

1. Meteorology Earth’s Revolution

2. Notes 1. One complete trip of an object in its orbit around the sun takes one year.

3. How many days does it take for the Earth to orbit once around the sun? Hint: How many days are in one year on Earth?

4. 2. Half the revolution of Earth around the sun equals one half a year (6 months).

5. Earth’s orbit around the Sun is counterclockwise.

6. 3. Revolution is the time it takes to complete one orbit. 9. Orbit-The path of a planet traveling around a star.

7. What is the difference between Earth’s rotation and Earth’s revolution?

8. Rotation is a complete spin on an axis, causing one day on Earth.

9. Is a year on other planets the same length as a year on Earth? Why or why not?

10. Planets are all different distances away from the Sun.
