Ruby planet is the closest and the smallest planet to the sun. Atmosphere is thin. The climate is harsh. And the days are too hot for typical fauna. So only the most adaptable life can exist here.
The Bright rock formations look like islands of stability in red shaded sand dunes that cover most of the planet. The sands sometimes shift and move. Geologists have a number of theories why this is happening. It might be an underground tunnel system that swallows tons of sand after tectonic plates move. It might be various quicksand underground deposits. Or even temperature differences in the day and night cycle could cause this phenomena.
Magnetic resonance shows that the Ruby planet's core is a Platonic solid shape of a tetrahedron. Rubian scientists sometimes even hesitate to call it a core because the spikes of the pyramid like tetrahedron is really close to the surface.
Climatologists link the core with weather temperature. The hottest part of the planet is the north pole cap which perfectly aligns with one of the vertices (spikes) of the “pyramid”. In comparisons the coolest climate title goes to the south pole which is the farthest point from the planet's core.
Scientists now are sending underground probes to survey the core. The biggest achievement would be to understand what material the tetrahedron is “made” from.
There are six major regions on the planet: The above-mentioned “Hottest” place on Ruby - the north cap. The still harsh but a bit cooler south cap. The vast Sea of Moving sands. Great Desert of Chali. The Great Rock archipelago. And the most geologically stable region, the Great plain, where “the Hub city” is located.
