Laplace was a Stanford Torus type colony used as the official residence for the prime minister of the Earth Federation Ricardo Marcenas. Laplace was intended to be an orbital bridge between the Earth and outer space. Two optical disks at the top and bottom provided solar power to the central donut-type residential block (Stanford Torus type). The residential block rotational period was seventy-five seconds, allowing it to generate a gravitational force similar to that of the moon.
