Dr Francisco Diego, Senior Research Fellow at the Department of Physics and Astronomy, University College London, told Mail Online: “Our solar system still has lots of loose rocks and debris from its mother cloud. When the earth encounters them, they burn and produce what is known as a shooting star. Large ones are called fireballs. In addition there are thousands of pieces of rockets, old satellites, etc. in low earth orbit and they eventually burn in the atmosphere. He said that the occurrence was nothing to worry about, despite the fact that meteorites can sometimes fall to earth and cause damage. This however is extremely rare.”
