Oops, I've realized the error in my ways in using that Java applet. I used NASA's accurate ephemeris generator instead and looked for local minima less than 0.2 AU between 1959 and 2004, and here's what popped out: Date Range (AU) 1964-Oct-21 0.1951679125 (Ranger 7) 1965-Feb-16 0.1257446466 (Ranger 9) 1972-Dec-29 0.0871449693 (Pioneer 10) 1980-Dec-18 0.0668657295 1982-Apr-11 0.185725114 (Venera 13) 1990-Apr-15 0.0300532941 (Galileo) 1998-Apr-15 0.0249093031 (Lunar Prospector) 2004-Dec-21 0.0964277899 That rules out Giotto. Lunar Prospector was launched on January 7, 1998. The approach on April 15 (9 Rmoon) was the closest since 1959 according to current data. _______________________________________________ ERPS-list mailing list [email protected] http://lists.erps.org/mailman/listinfo/erps-list
