Have you ever asked yourself that question?

Well, you’re not alone. It turns out that many, many people ask this same question every day.

The NASA All-sky Fireball Network is a network of cameras set up by the NASA Meteoroid Environment Office (MEO) with the goal of observing meteors brighter than the planet Venus, which are called fireballs. The collected data will be used by the MEO in constructing models of the meteoroid environment, which are important to spacecraft designers.

Amazing website. Pick a date in the left-hand column to see the fireballs that were recorded on that day. There are boatloads.
