Are there planets more suitable for life than Earth?

There are actually several ways for a planet to be even more hospitable than Earth for life.

One of these involves the axial tilt. The larger that is, the higher the average surface temperature. This, within limits, means that a planet highly tilted on its axis would be able to sustain on most of its surface a climate ranging from tropical to Mediterranean. In all likelihood, vegetation would be very abundant and able to support a greater number of species.

Another factor is the size of the planet, and consequently its mass and gravity. A large planet cools more slowly than a small one because the square-cube law implies that the surface area available to dissipate heat to space decreases in proportion to volume as size increases.

Losing heat less quickly and being more massive means a greater pressure pushing on the core, making it much more active than that of the Earth. This implies a stronger magnetic field and more vigorous plate tectonics than Earth’s. With the added bonus of northern lights occurring at very low latitudes.

Increased geological activity would lead to the formation of many small continents, as well as a huge number of atolls and archipelagos with thousands of islands. Such a fragmentation of the surface, would be ideal for stimulating speciation, and would…
