WebPaying attention to the fact that we start at Earth’s surface and end at 400 km above the surface, the change in U is. Δ U = U orbit − U Earth = − G M E m R E + 400 km − ( − G M E m R E). We insert the values. m = 9000 kg, M E = 5.96 × 10 24 kg, R E = 6.37 × 10 6 m. and convert 400 km into 4.00 × 10 5 m.
