Question 11 On Oct 31 2015 a massive asteroid TB145 nicknamed "Spooky" passed near the Earth. The measured diameter of the asteroid is 500meters and its speed relative to the Sun:36.0 km/s. (NOTE you are not given the parameters of collision, so they become important part of the "worst case -best case scenario.") Treat the asteroid as spherical object with the density of between 3g/cm³ to 6g/cm³. Treat an Earth orbit around the Sun as a perfect circle of radius 150 x 106 km. Take one year to be 365.24days. Find the Minimum energy released in the completely inelastic collision of this object with Earth. State your answers to the nearest mega-ton of TNT. (1 megaton of TNT= 4.184 x10^15J). Your Answer: Answer
