This simulation envisions what a giant mirror orbiting Earth would reflect in our sky.
When the disco moon is in low orbit, each reflection of the sun appears as a tiny sun, although you can never reflect enough light to get above the temperature of the surface of the sun (about 6000 degrees).
When as near as the ISS, the Earth surface to disco-ball-moon surface distance is 420 km or so. The orbital period in relation to the earth is realistic, about a 2.1 hour period.

Disco Ball Specs
The large mirror-tiles are 150km squared, and the small ones are 100km squared.
They are all 10 km thick with glass (with an IOR of 1.56)
There are 3012 mirrored tiles
