5577 Priestley (1986 WQ2) is an inner main-belt asteroid discovered on November 21, 1986 by Duncan Waldron at Siding Spring. It was named (following a suggestion from Robert H. McNaught) after Joseph Priestley, as co-discoverer of the element oxygen, because green emission in the aurora (astronomy), due to atomic oxygen, occurs at a wavelength of 5577 angstroms (557.7 nanometers).
