The orbit of 55P/Tempel–Tuttle intersects that of Earth nearly exactly, hence streams of material ejected from the comet during perihelion passes do not have to spread out over time to encounter Earth.
Putanja kometa 55P/Tempel–Tuttle skoro točno presijeca Zemljinu putanju, stoga potoci materijala otpala s kometa tijekom prolaza perihela ne moraju se vremenim raspršiti da bi naišli na Zemlju.
