The image shows positions of the Earth and the Moon. In which region would an astronaut feel the lightest?

Type the correct answer in each box, number only. Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2. So, if the mass of an object on Earth is 40 kilograms, its mass on the Moon is (a) kilograms.
