Asteroid-Asteroid Appulses - 2026 October

All dates and times are Universal Time

Positions are geocentric J2000 and include planetary perturbations

The first asteroid in the pair is the brighter of the two

Separations are in arcseconds, Position Angle is from the brighter asteroid to the fainter

Calculations by Brian D. Warner

Asteroid < mag 16; Elong from Sun > 45 degrees
