Asteroid 2024 PT5, once called a “mini-moon,” may have been a piece of the moon rather than an asteroid. Last year’s close encounter with Earth made it a near-Earth object before being ejected from the solar system. The study suggests it originated from the lunar surface after a collision. Its composition closely matches that of lunar rock, raising hopes for more clues about the moon’s history. This discovery highlights how objects in space can reveal secrets about our nearest celestial neighbor.
