how big is the earth?

Sounds like a dumb question. just google it, right? Bear with me...

More specifically, how big does Ingress think the earth is? And does it think the earth is a perfect sphere?

If I pick 2 points with lat/lon, how does Ingress calculate the distance? Still sound dumb? Bear with me...

I'm not looking for the EQUATIONS, i can get those from any maths textbook. I'm looking for the CONSTANTS.

Does Ingress assume a perfect sphere? of what RADIUS?

The equatorial radius of 6378km? The polar radius of 6357km? The global average of 6371km? The IAU nominal equatorial radius of 6371.1km? Some similar number with more bits of precision?

It starts to matter if you're trying to plan a 6882.28km link...
