In July 2005, astronomers Mike Brown, Chad Trujillo, and David Rabinowitz announced the discovery of a sun-orbiting object, since named Eris,8 that is 5% larger than Pluto. Eris orbits the sun once every 560 earth years at an average distance of about 6300 million miles from the sun. Based on its Position, how does Eris’s Distance from the sun (re-expressed to logs) compare with the prediction made by your model of Exercise 70?

Data From Exercise 70

The asteroid belt between Mars and  Jupiter may be the remnants of a failed planet. If so, then Jupiter is really in position 6, Saturn is in 7, and so on. Repeat Exercise 69, using this revised method of numbering the positions.  Which method seems to work better?
