g0 discrepancy in 1.2. Need clarification...

[GoSlash27]

According to the changelog, g0 has been changed to 9.80665 m/sec² and G is now 6.67408x10^-11 km³/s²

Does this now mean that Kerbin's mass has been changed to 5.28971x10²² g, or is there still a discrepancy between g0 by convention and g0 by calculation?

If the discrepancy exists, do I now use g=9.80665 for physics calculations, and g=9.810118 for flight planning? 

Confused...

Thanks,

Kerbin's mass likely hasn't changed because it's not a calculated value. The same would go for the rest of the solar system. I believe the change was in the engine code, and potentially elsewhere.

Or you can use µ and not bother considering G and planet masses (that is what astronomers do, because we have very poor accuracy on the value of G).

Though calculating the mass of Kerbin wouldn't be very hard.

 

Edit: assuming the orbital values for the Mun and Minmus on the Wiki are correct (big assumption), Kerbin's mass is 5.2915x10²² kg with the new value of G.

 

Edit2: and using values obtained from KER, I get 5.2897x10²² kg 

Well, we can conclude that Kerbin has two masses! Or that on rails orbits are wrong.

I'm wondering if/how orbits of vessels launched before 1.2 will be affected by this change.

 The mass has changed to accommodate. From the horses mouth:
