Titan Flyby - 28 December 2006
Just 16 days after Titan-21, Cassini returns to Titan for its twenty-third targeted encounter. During this last flyby of the year, Titan's gravity field will be measured by Cassini's radio science instruments in search for a potential subsurface ocean. The closest approach to Titan occurs on Thursday, 28 December, at 10:05:22 UTC at an altitude of 1300 kilometres above the surface and at a speed of 5.9 kilometres per second. The latitude at closest approach is 40.2° N and the encounter occurs on orbit number 36.
