The distance to Pluto is about 6E12 metres, you need half that distance to
accelerate and the other half to decelerate.

x = 0.5 g t^2 --> t = Sqrt(2x/g) = Sqrt(6E12/9.8) = 7.8E5 seconds = 9 days
So it takes 9 days to accelerate and 9 to decelerate. Ok, how fast are we
going after accelerating: 7.8E5 * 9.8 = 7.7E6 m/s = 2.1E6 km/h = 1.3E6 mph
That is 0.026c and it will give us a gamma of 1.0033
The total trip will take about 5.5 minutes less due to the relativistic effects.

No, that won't be necessary, I wouldn't have a purpose for them.

There you did it again :)
