Answer 2

Can Earth be considered a point mass when calculating the trajectory of a spacecraft landing on Earth?

When calculating the trajectory of a spacecraft landing on Earth, whether Earth can be considered a point mass or not depends on the mass and size of the spacecraft.

If the mass of the spacecraft is significantly smaller than the mass of the Earth, then Earth can be approximated as a point mass. This approximation is commonly used in celestial mechanics when analyzing the motion of objects in space. In this case, the gravitational force between the spacecraft and Earth can be simplified to a single force acting at the center of mass of Earth.

However, if the mass of the spacecraft is comparable to or larger than the mass of the Earth, then Earth cannot be considered a point mass. The gravitational interaction between the spacecraft and Earth would need to take into account the size and shape of both objects. The trajectory calculations would be more complex, considering the gravitational field of Earth and the gravitational forces acting on different parts of the spacecraft.

Therefore, the correct answer depends on the mass and size of the spacecraft. If the spacecraft is significantly smaller than Earth, Earth can be considered a point mass. If the spacecraft is comparable to or larger than Earth, Earth cannot be considered a point mass.
