Note to Students

This is not an exam. It is a Quiz. Some answers you may think you do not know, but they may be worked out by a process of elimination, looking for clues.

The BAAO Junior Astro competition is designed to engage and challenge students of all abilities by offering you a range of questions about astronomy and current space age exploration. The questions are about knowledge of the Solar System and observation of the night sky. Practical observation is a key part of astronomy and you should have some idea of the motion of the stars and planets. You will be able to gain more marks if they have some general knowledge of the subject through reading newspapers, magazines and books, listenening to the news, and by particpating in observation activities. i.e. go outside and view the night sky.

The key aim is that you should enjoy taking part and are encouraged to do more astronomy and broaden your interests. You do not need to cover technical topics. Some general knowledge and everyday interest in astronomy, or even some acquaintance with the GCSE in Astronomy which is available, would be an advantage.
