To determine which planet an object would weigh the most, you can refer to the mass of each planet. Weight can be calculated using the formula:
\[ \text{Weight} = \text{mass} \times g \]
where \(g\) is the acceleration due to gravity, which is directly proportional to the mass of the planet (assuming the radius is the same for the comparison).
Here are the estimated masses of the planets in the list you provided:
- Planet W: 6.4 × 10²³ kg
- Planet X: 3.3 × 10²³ kg
- Planet Y: 59.7 × 10²³ kg
- Planet Z: 48.7 × 10²³ kg
Since we are assuming that all the planets have similar radii, the weight of an object will be greatest on the planet with the highest mass.
From the data:
- Planet Y has the highest mass (59.7 × 10²³ kg).
Therefore, an object would weigh the most on Planet Y.
