Question
What exactly happens when a person see's a shooting star? Also, why are you sometimes able to see both the sun and the moon during daylight hours?
A shooting star is a meteor, a bit of cosmic dust burning up in the stratosphere. Look up meteor in Wikipedia. The Sun and the Moon are each up approximately half the time. Over half of its orbit around Earth, the Moon is up during daylight. Except when it is a thin crescent, the Moon is easy to see in the daytime sky, although surprisingly many people don't seem to notice it.
