Dillaa is the second planet from Sol. It is often compared to Avaya due to its similar size and mass. Dillaa, however, has no liquid water and has a thick atmosphere composed primarily of carbon dioxide that traps heat inside of the planet, making it incredibly hostile to intelligent life. Analysis of Dillaa’s atmosphere by Sayan research probes greatly accelerated scientific understanding of the greenhouse effect, contributing significantly to the global ecological movement and the discovery of climate change.
