NASA’s Dawn spacecraft is scheduled to reach the asteroid Ceres in February of 2015. Ceres is the largest asteroid ever discovered and orbits in the asteroid belt between Mars and Jupiter. Ceres has a mass of 9.46 x 1020 kg and a radius of about 4.25 x 105 m. What gravitational acceleration would Ceres provide on the spacecraft if it landed on the surface of the asteroid?
