Quizplus · Accepted Answer

The gravitational attraction between two objects is directly proportional to their masses and inversely proportional to the square of their distance apart. The mass of a newborn baby is very small compared to the mass of the Earth, so the gravitational attraction between them is relatively weak. The mass of all the planets in the solar system combined is much larger than the mass of a newborn baby, but they are also much farther away from the Earth. Therefore, the gravitational attraction between the Earth and all the planets is weaker than the attraction between a newborn baby and the Earth.
