Based on the TRIAD-catalogue and the Ephemerides of the Leningrad Institute for Theoretical Astronomy, orbits of 26 asteroids with small inclinations and one (or both) nodal points inside 1.5 AU are investigated to find objects appropriated for a near — asteroid fly-by in course of a Hohmann — transfer to Venus or Mars. Up to 1998 especially 2340 Hathor, 2062 Aten and 1982 XB could be visited on this way. Furthermore, the near-Earth positions of seven asteroids could be a cause for direct missions to these objects while a near — Mercury fly-by of 2340 Hathor in april 1991 has been found to be appropriated for a direct Hathor-Mercury mission. |
