You can't apply those real-world effects to Glorantha. Earth's Sun alway= s
seems to cover the same angle wherever it is in the sky because it's at a=

great distance, over twenty thousand times as far away as the radius of t= he
Earth. IF Earth's optical rules applied in Glorantha, the Red Moon would=

indeed look smaller as you got further away.

Our Sun's apparent size does vary slightly according to where Earth is in=

its orbit. You can't normally detect this with the naked eye, but 'annular' eclipses occur at times when the apparent size of the Sun is at=

its largest and the Moon does not cover it completely.
