Timeline of Cassini–Huygens burn slowed the spacecraft by close to 450 meters per second (about 1,006 miles per hour) relative to the Sun. "Cassini"s speed went from 67,860 kilometers per hour (42,168 miles per hour) at the start of the maneuver to 66,240 kilometers per hour (41,161 miles per hour) at the end of the engine firing. 24 June 1999 13:30 PDT – Gravity-assisted flyby of Venus at 623 km. 18 August 1999 03:28 UTC − Gravity-assisted flyby of Earth. An hour 20 minutes before closest approach, "Cassini" made the closest approach to the Moon at 377,000 km, and took a series of
