Meteoroids are a class of small rocky body that have also caused lots of wonder throughout history, but unlike comets, meteoroids regularly have an “impact” on the Earth. Meteoroids are the leftover remains of rock and metals from the formation of our Solar system. When a Meteoroid enters the atmosphere, it is travelling incredibly fast, between 11 - 72 kms
-1 (160,000 mph). Travelling at this speed through the atmosphere causes the Meteoroid to heat up until it starts to vaporise. This causes the Meteoroid to glow, producing a streak of light across the sky. It is now known as a Meteor. If any of the Meteor survives to impact on the ground, the remains are known as a Meteorite.
