Johannes kepler analyzed a large collection of data about the motion of objects in the solar system. he discovered that objects orbiting the sun follow a number of laws. one of these laws is that the size of an object's orbit times the square of its velocity is equal to a constant. if r is the size of the orbit (how far the object is from the sun) and v is the velocity, then
earth's average orbital velocity is about 6.7 times faster than that of the planetoid makemake. rounded to the nearest whole number, makemake's orbit is about times larger than earth's orbit.
