To determine which planet would gravitationally attract the spacecraft the least, we can compare the masses of the planets provided. The gravitational attraction of a planet depends on its mass: the greater the mass, the stronger the gravitational pull.
Here are the estimated masses of the planets in the given data:
- Venus: 4.87 x 10^24 kg
- Mars: 0.642 x 10^24 kg
- Jupiter: 1,898.0 x 10^24 kg
- Neptune: 102.0 x 10^24 kg
From these masses, we can see that:
- Mars has the least mass at 0.642 x 10^24 kg.
Therefore, Mars would gravitationally attract the spacecraft the least among the listed planets.
The answer is: Mars.
