Close Encounters with the Inner Planets

Last update: June 09, 2017

Computations: Francesco Manca , Piero Sicoli , Augusto Testa (obs.sormano@alice.it).


This table (sorted by date) reports asteroids with a nominal planet-miss distance within 0.5 million km for the coming years.

All data have been extrapolated from our technical list PCEL - Planetary close encounter list (see this page for more details).

Nominal miss distances in Km. are computed using a software developed at Sormano whereas minimum and maximum values based on a 3-sigma uncertainty confidence level are computed using OrbFit Software Package . All the distances are computed between the centers of mass of the bodies (Planet and minor body).

Take into account the Planets radii in order to refer distances from Planets surface.
