Computations: Francesco Manca , Piero Sicoli , Augusto Testa (firstname.lastname@example.org).
This table includes Comets with MOID (Minimum Orbital Intersection Distance) lower than 0.0350 AU with respect to planets Mercury, Venus, Earth and Mars.
Using a software developed at Sormano Observatory by A. Testa, their motions have been integrated for one hundred years to point out approaches within 0.0750 A.U. from each planet. Encounters for Disappeared or Lost Comets (DL) , and Sungrazing (SG) comets have not been taking into account.
MOID and possible approaches to planets for Long Period comets or in Parabolic and Hyperbolic orbits are also considered at the time of their apparition.
The list is a complement of our PCEL page that includes close approaches of asteroids to planets Mercury, Venus and Mars for the next two hundred years.
All the distances are computed between the centers of mass of the bodies (Comets and Planets).
