A forthcoming book by Daniel Patrick Quinn, Oscar Argudo and Jim Singh

Following the publication of The Relative Mountains of Earth: The Ribus, this new volume extends the idea of topographic prominence beyond our own planet.

The Ribu Baggers Guide to the Solar System is an exploratory guide to the most topographically prominent mountains and crater rims on other planetary bodies. Using modern digital elevation models produced by planetary missions, the project identifies and catalogues peaks with at least 1000 metres of topographic prominence on the best-mapped worlds of the Solar System.

While Earth contains 7,151 Ribus, more than 8,500 extraterrestrial Ribus have now been identified across neighbouring planetary bodies including Mercury, Venus, the Moon, Mars, Vesta and Ceres. Many of these alien landscapes host more prominentt mountains than any found on Earth and impact structures of extraordinary depth.

The book presents the first systematic prominence-based survey of these extraterrestrial landscapes. Each planetary chapter combines regional overviews with ranked indexes of the most prominent mountains, elevation lists and summit challenges for each world.

Alongside these mountains, the project also examines the Solar System’s deepest impact basins through the concept of “Negative Ribus”, immense depressions whose depths mirror the prominence of mountains.

The later chapters explore wider questions about planetary landscapes, including the problem of defining sea level on worlds without oceans, the geological origins of planetary mountains and how the concept of topographic prominence might apply to future exploration and even distant exoplanets.

The book is expected to be approximately 350 to 400 pages and will be released in both physical and digital formats, most likely in late 2026.

If you would like to be informed when the book becomes available to pre-order, you are welcome to send an email expressing interest and we will add you to the notification list.
