Bode's law

 We learn about the Mercury, Venus and the Earth. If you want to memorize sun to planets' distance, you should know  Bode's law. Bode is astronomer that discover this law.

Let's know about planets' orbit's radius. It can apply to only Mercury to Uranus.

Mercury:0.4AU
Venus:0.7AU
Earth:1AU
Mars:1.6AU
Jupiter:5.2AU
Saturn:10AU
Uranus:19.6AU

Let's ride those radius.
0.4,0.7,1,1.6,5.2,10,19.6

Let's multiply 10 to those numbers.
4,7,10,16,52,100,196

Let's take out 4 in those numbers.

0,3,6,12,48,96,192

Where is 24? In 2.8AU from the sun, there is asteriod belt. Uranus is discovered by this law
