> They block out most but not all of the sun. Interesting to think about: * How much mass could be positioned at L1 before changing the gravitational proposition of L1? * How large an object could be positioned at L1 before it exceeded the practical bounds of L1? * Presumably the object would reflect rather than absorb solar radiation. How would it deal with other solar ejecta?
