### Space Travel - Calculations

Posted:

**Thu Mar 01, 2012 12:27 pm**You said, in the early 22nd Century vid that I just watch, about space travel that you had not made the calculations just yet. Well I was bored and love math so...

All numbers are rounded to nearest 0.

- Pluto is ON AVERAGE approx. 38.5 AU from earth, which is 5 759 523 000 km. At Pluto's closest it is approx. 28.5 AU or 4 263 543 000 km.

- The fastest unmanned space craft is the New Horizons (actually destined for Pluto) traveling at on average 58 500 km/h or 1 404 000 km/day.

Average - 5759523000 / 1404000 = 4102 days = 11.24 years

Closest - 4263543000 / 1404000 = 3037 days = 8.32 years

- So at current fastest speeds and assuming scientists are smart enough (or Pluto is actually on it's closer orbit) to do it while Pluto is closer, that absolute best we could do is 8.32 years.

- Even if we could triple the speed of the spacecraft by the early 22nd Century it would still take at least 2.77 years to get to Pluto.

- To get to Pluto in 6 months we would have to travel 14 times faster then we currently can/do, 819 000 km/h

- Mars, without showing calculations, but using same current speed and closest Mars has ever been to Earth, 40ish days to get there.

Just food for thought on the idea about getting to Pluto nice and quick HAHA. Hope this helps in some way with something Matt! And really hope this didn't screw anything up???
