An extraordinary celestial event could unfold in the night sky in less than a decade if an asteroid passing Earth collides with the Moon. The impact of asteroid 2024 YR4 into the lunar surface would likely send debris flying out towards us, resulting in a unique meteor shower composed entirely of moon dust.

Two meteor showers will peak simultaneously Tuesday night into Wednesday, giving stargazers a celestial double feature. The Alpha Capricornids and the Southern Delta Aquarids will begin their peak late on July 29 into the early hours of July 30.
