Explaining The Universe on Instagram: "Spacecraft can use the gravity of planets or moons to change their velocity and direction through a technique called a gravity assist or gravitational slingshot. This method takes advantage of the motion and gravitational pull of a celestial body to boost or alter a spacecraft’s path without using extra fuel. When a spacecraft flies close to a planet or moon, it is pulled by the body’s gravity, gaining speed as it falls toward it and losing speed as it move

Venus rotates backwards compared to most planets, with a tilt of 177° and a slow rotation taking 243 Earth days. Earth spins once every 23 hours and 56 minutes with a tilt of 23.44°, rotating around 1,574 km/h. Mars has a 25.19° tilt and rotates in 24 hours and 37 minutes at 866 km/h. Jupiter
