Just for reference, the planet is 4.0×10^13 kilometres away, if we send our fastest ever probe, and assume it averages the top speed of 586,800 km/h all the way

Just for reference, the planet is 4.0×10^13 kilometres away, if we send our fastest ever probe, and assume it averages the top speed of 586,800 km/h all the way there, it will still take 7,781 years to reach the planet.

- _fizz_buzz_ 5y ago1) you also need time decelerate 2) speed of light is a hard limit, you cannot keep accelerating and you need more energy the closer you get to that limit
- tokai 5y ago> 1) you also need time decelerate No that would be a waste of effort. A flyby mission definitely makes the most sense. The 3.5 years are with deceleration though.
- empiricus 5y agoYou mean flyby at almost the speed of light? For interstellar travel, I think usable flyby speed is almost the same as stop and look around speed.
