How much would a 110-pound person weigh on Pluto?

7.33 pounds. Gravity on Pluto is ~ 1/15 that of earth. Jan 05 04, 11:43 PM

according to http://astrowww.astro.indiana.edu/~classweb/a100s0489/hw/hw11.html (weight on Pluto)/(weight on earth) = (0.00256)*(1/0.176)2 = 0.08 A 100 lb person weighs 8 lbs on Pluto. Therefore a 110 lb person would weigh 8.8 lbs according to http://btc.montana.edu/ceres/html/weight.html you would weigh 7.590000000000001 lbs so there seems to be a considerable variation between different sites.

6.49 pounds Oh. As there seems such a discrepancy I'd better say where I got my multiplier from: http://ks.essortment.com/weightonplan_rvrp.htm suggests you multiply the earth wight by 0.059 Jan 06 04, 8:14 AM

I agree with Stew. Pluto's gravity is just over 1/17th of that of the Earth's. Using NASA's own figures the multiplying factor is 0.059 which makes it 6.49 pounds. Jan 06 04, 12:00 PM

The source I have says that the acceleration due to gravity for Pluto is 0.29 m/s (to the 2nd power) thus a 110-pound earthling would weigh only 3 lbs on Pluto! The Handy Physics Answer Book (pg. 42) by P. Erik Gunderson... Jan 06 04, 11:06 PM
