Answer 1

To determine which planet an object would weigh the most on, we need to consider the mass of the planets, as weight is related to the gravitational force exerted by a planet, which is proportional to its mass (assuming the radius is similar).

Given the estimated masses:
- Planet W: \(6.4 \times 10^{23}\) kg
- Planet X: \(3.3 \times 10^{23}\) kg
- Planet Y: \(59.7 \times 10^{23}\) kg
- Planet Z: \(48.7 \times 10^{23}\) kg

Since all the planets are assumed to have similar radii, the gravitational force (and thus the weight) on each planet will depend primarily on their mass. The greater the mass of the planet, the stronger the gravitational pull and consequently, the more an object would weigh.

Among the provided planets, Planet Y has the highest mass of \(59.7 \times 10^{23}\) kg. Therefore, an object would weigh the most on **planet Y**.

So the correct response is:
**on planet Y**.
