How fast is the Large Hadron Collider?

The Large Hadron Collider (LHC) uses an array of 9,300 supercooled electromagnets to guide and accelerate particles – namely protons, around the 27km underground ring at CERN in Geneva, up to speeds extremely close to that of light. 

At their fastest, these particles travel at around 299.8 million metres per second completing 11,245 laps of this ring every second. This is equivalent to travelling around the circumference of the Earth seven and a half times in one second.
