It depends on how fast we travel, but we have examples of probes going to the different planets. It takes: Five months to Mercury by Mariner 10 [United States] Four months to Venus by Venera 10 [Soviet Union] Seven months to Mars by many different probes Two years to Jupiter by Voyager 1 and Voyager 2 Six years to Jupiter by Galileo Four years to Saturn by Voyager 1 and Voyager 2 Seven years to Saturn by Cassini Eight and one-half years to Uranus by Voyager 2 Twelve years to Neptune by Voyager 2 In comparison, it only took a few days for astronauts to travel to the Moon.
