期 = 其 + 月 : Recently the Queen of Hearts (qi) has become an astronomer. In front of the space station (Ø1) she sits on top of a watchtower (其) and watches the moon (月). From the moon's movement around the tower she wants to calculate its period and phase (期). She didn't consider though that not only the moon is orbiting around her, she is also orbiting the moon.
