AbstractThe collision velocities with Mars of the known periodic comets with perihelion distances less than the orbital radius of Mars 1.52 au are calculated and statistically analyzed. The velocity distribution shows that short-period comets usually have smaller collision velocities than the long-period comets whether they are numbered or unnumbered. For comets with period P less than or equal to 270 y, most collision velocities with Mars are less than 30 km s(-1). These velocities are smaller than the corresponding collision velocities with Earth. Based on the similarity of the velocity distributions of the comets and meteoroid streams, meteor showers on Mars are discussed briefly.
