P2 8 Avoiding Exams To The Extreme

Tom Halliday, Oliver J. T. Brough, Corban C. B. Gardiner, Joel E. Grout


This paper determines the velocities and consequential forces needed to move the Earth to outside of the habitable zone (0.7 AU). A Hohmann transfer is used and requires two changes in velocity, first at 2,700 m/s to achieve an elliptical orbit and second at 2,900 m/s to achieve a closer circular orbit. The forces required are 1.87 x 10^22 N and 1.34 x 10^22 N respectively.
