Abstract
Abstract Near-Earth asteroid 138175 (2000 EE104) will soon be temporarily resonant with Earth, but has a much longer residence in an orbit which features a trapping behaviour with frequent Earth and Venus encounters. The object has been identified as a possible source of material for interplanetary field enhancements, a magnetic phenomenon in the solar wind inferred to be due to dust arising from secondary collisions with 10-m scale objects injected into its path. Its horseshoe libration will be reversed by a very close encounter with Venus in 2251 CE. We characterize the orbit of this asteroid, model the dispersion of the primary collision products along its path, and discuss the non-gravitational motion of secondary dust in the solar wind.
