placeAroundfunction

A place helio astronomical units from the Sun (a planet, or a point on its orbit), round the Sun at sun. True: as it is. Compressed: the same direction from the Sun, at 44 Earth radii times its distance in astronomical units to the power 0.45, so the Earth's own orbit is the 44 and Neptune's is about 200 (30 times as far, really).
