The protons accelerated inside the Large Hadron Collider travel at 99.9999991% of the speed of light, so fast that they complete the full 27 km ring approximately 11,245 times per second. In one second, a proton in the LHC travels approximately 300,000 km, roughly the distance from Earth to the Moon.
