\section{Where do the Perseids come from? Why is today showtime?}
Meteor showers are usually called from the apparent direction  from which the meteors seem to come from, which in this case is the \href{https://en.wikipedia.org/wiki/Perseus_(constellation)}{constellation of Perseus}. The Perseids occur when the Earth comes close to the dusty trail of a periodic comet known as Swift-Tuttle, which last returned to the inner solar system in 1992. Next time the comet will swing by is in 2125. In the meanwhile,  another planet is going to play an important role for this year event. Jupiter. The giant planet recently nudged with its gravity Swift-Tuttle's debris closer to Earth's orbit. This is why astronomers expect this years' shower to be a particularly exciting one, and we could see up to 150/200 meteors per hour the night of August 11/12!
