Unformatted text preview: m at perihelion (closest approach), to 1.52 x 10 11 m at aphelion (farthest distance away). The suns mass is 1.99 x 10 30 kg, the Earths mass is 5.98 x 10 24 kg. a) What is the maximum change in the Earths gravitational potential energy during one orbit of the sun? (1.8 x 10 32 J) b) At what point in its orbit is the Earth moving its fastest, and what is its maximum change in kinetic energy? (perihelion, 1.8 x 10 32 J) A:\sph4u1\chap6\day04potenergysht.doc...
