Answer: Swift-Tuttle
Explanation:
Perseid meteor shower is annually observed in August. This phenomenon occurs because the pieces of the Swift-Tuttle comet (also called 109P / Swift-Tuttle and discovered by Lewis Swift in 1862 and by Horace Parnell Tuttle in 1862, independently) collide with the Earth atmosphere at high speeds.
This is also due to the debris cloud formed by the pieces of cometary residue moving along parallel orbits, so when entering the atmosphere they leave burning traces that seem to come from a common radiant point in the sky, located in this case at the Perseus constellation.
