Earth fly-bys: March 2005, November 2007 and November 2009

To gain speed through a series of gravitational 'kicks', Rosetta flies past the Earth three times during its journey. The fly-by distance is between 300 and 14 000 km. Manoeuvres to correct Rosetta's orbit take place before and after each fly-by.
