What if Earth’s greatest mysteries are all connected?

The Moon’s strange origins.
A billion missing years in Earth’s geological record.
Sudden explosions of life, mass extinctions, lost continents, and ancient catastrophe myths found across every culture.

In The Ninth Visitor, Phillip J. Fenton presents a bold, interdisciplinary theory that challenges conventional views of Earth’s past. Drawing on astronomy, geology, paleontology, archaeology, and mythology, the book proposes that a massive, undiscovered planet, Planet X, periodically passes through the inner solar system, triggering global upheaval.

According to this model, one such encounter stripped away part of Earth’s outer crust, forming the Moon and reshaping the planet’s surface. The aftermath, Fenton argues, explains ocean basins, abrupt climate shifts, the Cambrian explosion of life, and humanity’s persistent legends of lost worlds and celestial destruction.

Provocative yet accessible, The Ninth Visitor does not ask readers to reject science, but to question whether Earth’s story is incomplete.

For readers fascinated by planetary science, deep time, lost civilisations, and radical new ideas, this book offers a sweeping re-examination of our world, and a haunting question: are we living in a rare calm between cosmic returns?
