Cruithne is discovered by Duncan Waldron on a photographic plate taken with the UK Schmidt Telescope at Siding Spring Observatory, Coonabarabran, Australia. Cruithne and Earth appear to "follow" each other in their paths around the Sun, this is why Cruithne is sometimes called "Earths second moon", however, it does not orbit the Earth and is not a moon
