Hubble's law (E.P. Hubble; 1925):
A relationship discovered among distance & radial velocity. Further away a galaxy is away from is, the quicker it is receding away from us. The constant of proportionality is Hubble constant, H0. The cause is interpreted such as the expansion of spacetime itself.
Determine q, q = ax2¬- 2by + c2z2 where a, b and are c are constant at (1, -2, 3)
parsec: The unit of distance explained as the distance mentioned by an Earth-orbit parallax of 1 arc sec. It equals approximate 206 264 au, or about 3.086 x 10 16 m.
