Abstract

On May 9 the Minor Planet Center announced the re-discovery of the last `lost' minor planet, (719) Albert. In this paper we study its orbital evolution. We show that Albert follows an extremely chaotic orbit, typical of near-Earth asteroids (NEAs) that are extracted from main belt resonances through close planetary encounters. It will become an Earth-crosser and, eventually, it will either be ejected from the solar system on a hyperbolic orbit or will become a Sun-grazer, most probably within the next 5 Myrs.

Key words: minor planets, asteroids – celestial mechanics, stellar dynamics – chaos
