Where does the magic number

come from ? -- DavidCary 19:17, 12 May 2004 (UTC)
- It's the gravitational constant in other units:
- <math> \sqrt{G} = \sqrt{ 6.67*10^{-11}\; \mathrm{N\,m^2/kg^2}}<math>
- <math> = \sqrt{6.67*10^{-11} \frac{\mathrm{m}^3}{\mathrm{s}^2 \mathrm{kg}}} <math>
- <math> = \sqrt{ 6.67*10^{-11}
\frac{(86,\!400)^2 * (1.9891*10^{30})}{(1.496*10^{11})^3}
\frac{\mathrm{AU}^3}{\mathrm{day}^2 \;\mathrm{mass}_{Sun}} } <math>
- <math> = 0.0172\;\; \mathrm{AU}^{3/2}\; \mathrm{day}^{-1}\; \mathrm{mass}_{Sun}^{-1/2}<math>
