The weight of an object on a planet is directly proportional to the mass of that planet, assuming similar radii. The planet with the largest mass will exert the greatest gravitational force on an object.

Based on the estimated masses provided:

  • Planet W: 6.4 x 10^23 kg
  • Planet X: 3.3 x 10^23 kg
  • Planet Y: 59.7 x 10^23 kg
  • Planet Z: 48.7 x 10^23 kg

The planet with the largest mass is Planet Y (59.7 x 10^23 kg). Therefore, an object would weigh the most on Planet Y.

The correct response is: on planet Y
