# Time dilation earth

I have calculated the clock rate difference between the surface of the sun and at the position of the earth’s orbit relative to the sun.

$$t_0 = t_f \sqrt {1 - \frac{{2GM}}{{rc^2 }}}$$

I hope the LaTex equation above is displaying correctly. In the preview it is picking up some other equation.
Should be t0=tf(sqrt(1-2GM/rc^2))

Mass of Sun 2x10^30 kg
