The book “Our Mysterious Spaceship Moon” by Don Wilson (Dell, 1975) [6] asks how we can explain why rocks on the moon are older than our solar system?
Here’s what we can say about this from the best data we have in 2023:
The estimated age of the solar system is approximately 4.6 billion years. This age is determined through the study of the oldest accessible materials, such as meteorites, which provide a valuable insight into the early history of the solar system[1][2][3][5]. The age of the Earth is around 4.54 billion years, and the age of the oldest moon rocks is estimated to be between 4.46 and 4.51 billion years old, making the moon slightly younger than the Earth[1][2][5]. These ages are determined using radioactive dating techniques and the analysis of various celestial bodies and their components[3][5].
Therefore, the age of the rocks on the moon, as far as the current data shows, is younger than both the earth and the solar system.
