Nearby asteroid passages

The following database contains the orbital data of asteroids that approached at a distance of less than 10 ld (lunar distance->Earth-Moon distance) sorted by distance, starting from 12/09/2024.The data come from NASA-JPL. The database is updated every 3 months.

Explanation of symbols

des - primary designation of the asteroid or comet (i.e. 443, 2000 SG344)

orbit_id - orbit ID used for the close-approach computation

jd - time of close-approach (JD Ephemeris Time, TDB)

cd - time of close-approach (formatted calendar date/time, TDB)

dist - nominal approach distance (au)

dist_min - minimum (3-sigma) approach distance (au)

dist_max - maximum (3-sigma) approach distance (au)

v_rel - velocity relative to the approach body at close approach (km/s)

v_inf - velocity relative to a massless body (km/s)

t_sigma_f - 3-sigma uncertainty in the time of close-approach (formatted in days, hours, and minutes; days are not included if zero; example “13:02” is 13 hours 2 minutes; example “2_09:08” is 2 days 9 hours 8 minutes)

h - absolute magnitude H (mag)
