« on: December 01, 2015, 12:07:39 PM »Stationary orbit refers to a specific orbit around a planet or a moon which has same cycle length as the planet(or moon)s' revolutionary cycle. Any satellite in this orbit remains same position relative to a point on surface. On the Earth, it is something like 30,000km above surface. On Eventide, it would have to be far, far away. A day is(or is nearly) an year so cycle is longer.And due to being further away the mirrors would have to be much larger to achieve the same effect. Like approaching "that's no moon" large.
Either that or create an even bigger hugenormous mirror to sit at L2.
[edit]
I'm trying to have a go at working out exactly how far out the mirrors would need to be, but I've got as far as figuring out Earth has an equatorial velocity of ~460 m/s-1. If it were tidally locked it would have a Veq of 460/365 --> ~1.2 m/s-1. Big orbits required to hover over something going that slow. How big? I don't know, my head is literally swimming looking at these formulae. I am awful at numbers.
Not touched this stuff in nearly 20 years. Damn yooooooooooou spaaaaaaaaaace gaaaaaaaaaaame!
