Sormano Astronomical Observatory: Table of Next Closest Approaches to the Earth by Asteroids

Last update: March 07, 2010

Computations: Piero Sicoli, Francesco Manca (sormano@tin.it).

This table reports asteroids with nominal Earth-miss distance within about 1.5 millions km (sorted by date) for the coming years.

All data have been extrapolated from our Minor Body Priority List and the Small Asteroids Encounters List (see these pages for more details).

Some objects are listed in the risk page at JPL (NASA) and NeoDys (Univ. Of Pisa, Italy) about possible impacts with our planet (see NeoDys Risk page and SENTRY Risk page). Torino and Palermo Impact Hazard Scale are also reported.

All the distances are computed between the centers of mass of the bodies (Earth and asteroid).

Predicted close encounters with the Earth ( geocentric distance )

Astronomical Unit (average distance between Earth and Sun)= 149600000 km

The average distance between Earth and Moon = 384400 km

Earth Radii= 6378.14 Km

Table Headings:

Object:
definitive number and name or provisional designation.
Range of size:
Probable size of the object from its absolute magnitude (H). For more information on this matter see the related page at the Minor Planet Center. A small range reported in italic suggests that the size has been deduced directly from radar observations.
Date:
Year, month, day of the close approach to the Earth.
Nominal distance:
Miss (geocentric) distance as resulting from nominal orbital elements.
Min and Max distance:
minimum and maximum miss possible distance based on the 3-sigma uncertainty confidence level. A simbol '**' means not computed, usually owing to a very high uncertainty.
The Palermo technical Scale:
Palermo Scale values between -2 and 0 indicate situations that merit careful monitoring. For more explanation see the related web page The Palermo technical Impact Hazard Scale
Torino Scale:
The Torino Impact Hazard Scale is designed to communicate to the public the risk associated with a future Earth approach by an asteroid or comet (see image below)
