How long does it take to get to Jupiter from Earth? The distance between Earth and Jupiter varies depending on where the two planets are in their orbits around the sun. So the time it takes to travel to Jupiter from Earth depends on the distance between the two planets at the time of launch. It also depends on the speed of the spacecraft and the path chosen. Below is a list of launch and arrival times between Earth and Jupiter for some past missions.
