New Delhi, (PTI) The Moon may be at least 4.46 billion years old, according to a study that pushes back the age of the lunar body by 40 million years.
Over four billion years ago, when the Solar System was still young and the Earth was still growing, a giant object of the size of Mars crashed into our planet. The biggest piece that broke off of the early Earth formed the Moon, the researchers said.
However, the precise time when this happened continues to be a mystery, they said.
