I'm trying to understand the Schwarzschild solution concept of proper distance. Given the proper distance equation(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

d\sigma=\frac{dr}{\left(1-\frac{R_{S}}{r}\right)^{1/2}}

[/tex]

how would I calculate the coordinate distance. For example - assuming the distance from the Earth to the Sun is 150,000,000km, is it a valid question to ask what the coordinate distance is, and how would I calculate it?

I know [itex]R_{S}[/itex] is about 3km.

Many thanks
