Between the orbits of Mars and Jupiter, several thousand small objects called asteroids move in nearly circular orbits around the Sun. Consider an asteroid that is spherically shaped with radius r and density 2000 kg/m^3. 1. You find yourself on the surface of this asteroid and throw a baseball at a speed of 24 m/s. If the baseball is to travel around the asteroid in a circular orbit, what is the largest radius asteroid on which you are capable of accomplishing this feat?
Answers: 1
![r = \frac{v^2}{ \sqrt{G * \rho * [\frac{4}{3} ] * \pi} }](/tpl/images/0847/4737/c463c.png)
![r = \frac{24^2}{ \sqrt{ 6.67*10^{-11} * 2000 * [\frac{4}{3} ] *3.142 } }](/tpl/images/0847/4737/3a9da.png)
