A well-known feature of our solar system is the asteroid belt between Mars and
Jupiter. One theory about the asteroid belt is that it's made of primordial
material that was prevented from forming another planet by the gravitational
pull of Jupiter when the solar system was formed. One of the largest asteroids
is 951 Gaspra. Its distance from the Sun is 207.16 million miles. Use your linear
regression equation to interpolate the length of its sidereal year.
