Cassiopeia the queen and Venus

A story about space — There are big planet and small planets. Which planet fits the crown of Cassiopeia the queen? — Cassiopeia the queen wished for a jewel in her crown. A golden crown would just not do without a jewel in it too. She called in the planets one by one. Surely one would be her jewel. A jewel so shiny, fine and bright. To make her crown look cool. She tried the planet mercury, the tiny one, nearest the sun. Oops! She tried the gas giant Jupiter, too big to be the one. The last she tried was Venus, gleaming bright, the evening star. A jewel in her crown, the perfect fit, the brightest planet by far.
