Answer 1

The weight of an object on a planet depends directly on the planet's mass. Assuming that all planets are similar in radius, the planet with the greatest mass will exert the strongest gravitational pull, and therefore an object would weigh the most on that planet.

From the table provided, the estimated masses of the planets are as follows:

• 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

Among these, Planet Y has the greatest estimated mass (59.7 x 10^23 kg).

Therefore, an object would weigh the most on planet Y.
