- (a) What is the escape speed on a spherical asteroid whose radius is 502 km and whose gravitational acceleration at the surface is 0.870 m/s? (b) How far from the surface will a particle go if it leaves the asteroid's surface with a radial speed of 647 m/s? (c) With what speed will an object hit the asteroid if it is dropped from 665.5 km above the surface? (a) Number i Units (b) Number Units (c) Number UnitsIn 2014, the Rosetta space probe reached the comet Churyumov– Gerasimenko. Although the comet’s core is actually far from spherical, in this problem we’ll model it as a sphere with a mass of 1.0 x 1013 kg and a radius of 1.6 km. If a rock were dropped from a height of 1.0 m above the comet’s surface, how long would it take to hit the surface?Planetary motion. A planet or asteroid orbits the Sun in an elliptical path'. The diagram shows two points of interest: point P, the perihelion, where the planet is nearest to the Sun, and the far point, or aphelion, at point A. At these two points (and only these two points), the velocity v of the planet is perpendicular to the corresponding "radius" vector ř, from the Sun to the planet. An arbitrary point Q is also shown. P A
