GD 40 is a white dwarf in the constellation Cetus. It is located about 212 light-years (65 parsecs) away from the Sun.[1] The star's spectrum has been found to show traces of external of metal contamination due to disruption of an extrasolar dwarf planet or an asteroid.[3] The disrupted object should have had roughly the same mass of the Solar System asteroid 3 Juno.
