`implies` The square of the time `(T^2)` period of revolution of a planet is proportional to the cube `(a^3)` of the semimajor axis of the ellipse traced out by the planet.
`T^(2) prop a^3`
`:. Q = T^2/a^3`
a = semi major axis in unit of `10^(10) m`
T = period of revolution of planet in year (y)
`Q= T^2/a^3` , the quotient in unit of `10^(-34) y^(2) m^(-3)`
