It would appear that the moon is very old, it turns out.
A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
Some studies have come up with similar estimates, while others have argued for a younger moon that coalesced 150 million to 200 million years after the solar system was born. The new findings are published in the journal Science Advances.
