Why is Voyager 1 travelling at 17 km/s?

Best Answers

Voyagers 1 and 2 are both traveling at speeds close to 17 km/s, with Voyager 1 moving about 10% faster than Voyager 2. read more

Voyagers 1 and 2 are both traveling at speeds close to 17 km/s, with Voyager 1 moving about 10% faster than Voyager 2. These spacecraft were launched separately in 1977, with a rocket (Titan III) providing the initial escape velocity relative to the Earth. read more

My calculations come to 15.646 kms, not significantly less than 17 kms from an observer's standpoint, but in terms of extraordinary long travel distance, it would be. To travel 1,000,000 km it would take 63,914.1 hours; at 17 kms it would take 58,823.5 hours, or, 212.13 days less. read more

The spacecraft was traveling at 17.043 km/s (10.590 mi/s) relative to the Sun. It would need about 17,565 years at this speed to travel a light-year. To compare, Proxima Centauri, the closest star to the Sun, is about 4.2 light-years (2.65 × 10 5 AU) distant. read more
