If you trace all the Perseid meteors backward, they all seem to come from the constellation Perseus, near the famous Double Cluster. Hence, the meteor shower is named in honor of the constellation Perseus the Hero. However, this is a chance alignment of the meteor shower radiant with the constellation Perseus.
What exactly is the Perseid meteor shower?
The Perseids are a prolific meteor shower associated with the comet Swift–Tuttle. The meteors are called the Perseids because the point from which they appear to hail (called the radiant) lies in the constellation Perseus.
Where do the Perseids come from?
NASA says the Perseids originate from the Swift-Tuttle comet, which takes 133 years to orbit the Earth and last visited the inner solar system in 1992. The shower takes its name from the Perseus constellation, the point in the sky from which it appears.
