According to Business Insider, The Leonid meteor shower, which is known for its bright streaks across the night sky, is going to reach its viewing peak this weekend. The Leonid meteor shower can be seen between the hours of 12 a.m. and 6 a.m. from November 17th through the 18th. About 20 meteors are expected to appear per hour. Parts of the western and southeastern US will have the best viewing conditions. Meteor showers occur when the Earth moves through a dense cloud of comet debris during its orbital journey.
