The Perseids /ˈpərsiːɪdz/ are a prolific meteor shower associated with the comet Swift–Tuttle. The Perseids are so called because the point from which they appear to come, called the radiant, lies in the constellation Perseus. The name derives in part from the word Perseides (Περσείδες), a term found in Greek mythology referring to the sons of Perseus.
The stream of debris is called the Perseid cloud and stretches along the orbit of the comet Swift–Tuttle. The cloud consists of particles ejected by the comet as it travels on its 133-year orbit. Most of the particles have been part of the cloud for around a thousand years. However, there is also a relatively young filament of dust in the stream that was pulled off the comet in 1865, which can give an early mini-peak the day before the maximum shower. The dimensions of the cloud in the vicinity of the Earth are estimated to be approximately 0.1 astronomical units (AU) across and 0.8 AU along the latter’s orbit, spread out by annual interactions with the Earth’s gravity.
Walking through the dark night
Raise your eyes into dark sky
May your face be run with light
Let your lungs be filled with cry
Let it go from where it comes
Let this spirit flow and rush
Let it stay as always does
Feel the freedom. Let it gush.
Then watch over as it burns into your heart
It's the feeling that strikes you like a dart
Never know when it's coming to it's end
And you never know when your impulse to be sent
Let it seize and fill you up
Let it flow through all your guts
Wonder if prepared you are
Then beware of leaving a scar
Let it go from where it comes
Freedom forged for everyone
Let it stay as always does
But it's gone for some of us
