It was once thought that our solar system ended at Saturn. Then the first telescopes revealed Uranus and Neptune. Differences in the calculations of the gravity of these giants set off another search and Pluto was discovered. Pluto was then thought to be the last planet of our solar system. Beyond it was empty space – until astronomers started looking at comets. Huge balls of ice, zipping through the solar system, past the planets, around the sun and back out again.

More space objects have been found beyond Pluto, in a region known as the Kuiper Belt. In 2003, Eris was discovered. Its existence was confirmed in January 2005. It was found to be larger than Pluto and was put forward as a tenth planet in our solar system. This caused much debate among astronomers. Are there more, larger objects in our solar system? How many? Are they all to be considered planets? If not, then what does this mean for Pluto? On August 24, 2006, the International Astronomical Union (IAU) came up with a scientific definition of the word “planet”. Pluto did not fit these new rules. It was downgraded to “dwarf planet”. The IAU is reluctant to consider any more than eight planets in our solar system. All other planet-like bodies are to be known as “dwarf planets”. How much do you know about these dwarf planets? Do you know: What is a plutoid? How many official dwarf planets are there in our solar system? Are all the dwarf planets out beyond Pluto? How big does an object need to be to qualify as a dwarf planet? What other rules must an object meet to be classified as a dwarf planet?

Ears sit on opposite sides of our head. They are flappy bits of skin that stick out. Sometimes we decorate them with piercings. Ears are our own little satellite dishes. They pick up sound waves and send them through the ear canal, where the tiniest bones and muscles in our body pick up the vibrations and send them further into our ears. Through a journey of air and liquid, our brains finally get the message and tell us that we have heard something. Our ears are also responsible for making sure we don’t fall flat on our face. Let’s see how much you know about ears. Can you answer these questions? How many parts does your ear have? How many types of fluid are supposed to be in your ear?
