The graph shows that 36 km/s is the escape velocity of the solar system at the Earth. But if we do some calculations, we will get 42.1 km/s as the right answer. I have been checking all other escape velocities of the solar system at the different planets from the graph, and they match with the real values. But the Earth escapes velocities do not match. Am I missing something or is it wrong?
sqrt((6.674E-11*1.989E30 *2)/(149.6E9)) = 42126.918623693244 km/s
