Suppose a body with a radius of 15 km hits a planet at a velocity of 30 km s−1. Assume the evaporative loading parameter is ∼20. (a) Calculate the mass of the atmosphere blown into space if the impactor hits the Earth. (b) Calculate the mass of the atmosphere blown into space if the impactor hits Venus. (c) Calculate the mass of the atmosphere blown into space if the impactor hits Mars. (d) Express the masses of escaping gas calculated in (a)–(c) as a fraction of each planetary atmosphere’s mass.
