An amateur astronomer may have found another moon of the Earth. Experts say it may have only just arrived.
Much uncertainty surrounds the mysterious object, designated J002E2. It could be a passing chunk of rock captured by the Earth’s gravity, or it could be a discarded rocket casing coming back to our region of space.
It was discovered by Bill Yeung from his observatory in Arizona and reported as a passing Near-Earth Object. It was soon realised however that far from passing us it was in a 50-day orbit around the Earth.
