Scientists: Moon over the hill at 4.51 billion years old

In this Feb. 13, 1971 file photo, Apollo 14 astronaut Alan B. Shepard Jr. conducts an experiment near a lunar crater, using an instrument from a two-wheeled cart carrying various tools. On Wednesday, Jan. 11, 2017, a California-led research team reported that the moon formed within 60 million years of the birth of the solar system. Previous estimates ranged within 100 million years, all the way out to 200 million years of the solar system’s creation.
It turns out the moon is older than many scientists suspected: a ripe 4.51 billion years old.
