Distance to Pandora
 

has anyone else actually tried to find it?

well, i calculated it to be about 41220551605927.68 km

this is only as correct as the distance is 4.36ly.

at a total average speed of 809770383.583 km/h, you will arrive there in 2121 days. The ISV Venture Star took this long, calculating leap years and each month in travel. I spared no detail in calculating this.(not true, i didn't calculate acceleration or deceleration, couldn't find the exact time of either in days.)

[5 years = 1826 days, one leap year in [Venture Star's] journey, 9 months = 273 days, (3•30)+(1•28)+(5•31), 22 days = 22 days] = 2121

Yeah. If you use Wolfram Alpha, it tells and converts most things. I think the figure given for the ISVs to reach Pandora includes acceleration and deceleration though (which is a couple of months of the start and end of the trip)
