This means the space rock’s orbit occasionally crosses paths with or cuts into the Earth’s journey around the Sun.
When NEOs swing around our planet, they are tracked and analysed by NASA’s Centre for Near Earth Object Studies (CNEOS) at the JPL and California Institute of Technology.
The Centre’s asteroid findings are coordinated with NASA’s Planetary Defense Coordination Office in the event a space rock should threaten the Earth.
NASA said: “In the event of a predicted impact such as for 2008 TC3, CNEOS predicts the impact time, location and geometry.
