I've learned that a man named Bode came up with a formula for finding planets. It is first you start with 0 + 4/10= 0.4 mercury. Then double it into a continuum.1 AU = 93,000,000 Mi.
1 light year : 5,869,713,900,000 mi. Closest star Proxima Centauri:23,478,855,600,000 Mi.
Pluto is not a planet. Mercury is the smallest planet. Jupiter is the largest planet.
