Comets are bodies composed of rock, ice and dust. They are visitors from the distant reaches of our solar system. As a comet comes close to the sun, it warms up and the icy surface vaporises, resulting in a coma surrounding the nucleus. While the nucleus itself is typically only a few kilometres wide, the coma extends for several thousand kilometres. Gasses and dust are expelled, creating the tail they are known for. In fact, oftentimes we can observe two tails: a dust tail that reflects sunlight and an ion tail that glows blue via the ionisation of gasses. In turn, the dust left behind by comets results in meteor showers (i.e. shooting stars). When Earth happens to intersect with such ‘leftover’ dust, these grains burn upon impact with our atmosphere, leading to scurrying lights in the sky. Thus, different comets are responsible for different meteor showers. For example, the famous Perseids in August are due to Comet 109P/Swift-Tuttle while the Orionids of October/November due to comet 1P/Halley.
