To determine which planet would gravitationally attract the spacecraft the least, we can look at the estimated mass of the planets. The gravitational attraction of a planet is directly related to its mass; the larger the mass, the stronger the gravitational force.
From the provided data:
- Venus: 4.87 x 10²⁴ kg
- Mars: 0.642 x 10²⁴ kg
- Jupiter: 1,898.0 x 10²⁴ kg
- Neptune: 102.0 x 10²⁴ kg
Among these, Mars has the lowest estimated mass (0.642 x 10²⁴ kg). Therefore, Mars would gravitationally attract the spacecraft the least.
So the correct response is:
Mars
