Question

In January 2005 the Huygens probe landed on Saturn's moon Titan, the only satellite in the solar system having a thick atmosphere. Titan's diameter is 5150km , and its mass is 1.351023kg . The probe weighed 3410N on the earth.

Problem 6.29: Huygens Probe On Titan. In January 2005 the Huygens probe landed on Saturn's moon Titan, the only satellite in the solar system having a thick atmosphere. Titan's diameter is 5150km , and its mass is 1.35 x 10^23kg . The probe weighed 3410N on the earth. Part A What did it weigh on the surface of Titan?

Explanation / Answer

g on titan = GM/r^2

g = 6.67e-11* 1.35e23/(2575000)^2

g = 1.358 m/s^2

W = mg = 2130 N

so mass m = 2130/9.8 = 217.34 kgs

so

Weuight on titan = 217.34* 1.358 = 293.41 N
