Answer: Sun loses mass is through nuclear fusion. As the Sun loses mass its gravitational pull on the Earth weakens over time. As a result, Earth is receding slightly from the Sun. Because of the solar mass loss the Earth's distance from the Sun increases by about 1.6 centimeters per year.
39 inches is the longest bc a foot is 12 inches and the longest feet the is 3 feet or a yard. So 12 x 3 = 36 and that is 3 inches short than 39 so 39 is the longest.
