* Meteors are not solid objects: A meteor is a streak of light caused by a small piece of space debris (a meteoroid) burning up in the Earth's atmosphere. They are not solid bodies with a definable shape.
* Short-lived phenomenon: The entire event of a meteor burning up takes only a few seconds.
What you may be thinking of:
* Rotation of asteroids: Some asteroids do rotate, and their rotation periods can be measured. It's possible you're thinking of an asteroid, which is a much larger space rock.
* Rotation of Earth: The Earth rotates on its axis every 24 hours, which is why we have day and night.
