The planets discovered resemble Neptune but exist beyond our solar system. These Neptunian exoplanets offer clues about how planetary systems outside the Milky Way form, migrate, and evolve across cosmic environments.
The Neptunian Desert is nearly devoid of planets due to intense stellar radiation that strips atmospheres, leaving rocky cores. The few survivors in this barren region reflect the harsh environmental forces at play.

In contrast, the Neptunian Savannah offers a more hospitable zone, with planets retaining their atmospheres for millions of years. This region shows how planetary environments can foster longevity in favorable conditions.

The Neptunian Ridge is a dense region where many planets have migrated. It acts as a transition zone, offering a glimpse into planetary dynamics and how celestial bodies navigate their environments over time.
Planets in the Neptunian Ridge may have moved through high-eccentricity tidal migration, a process allowing planets to shift toward stars at any life stage, reshaping their characteristics and trajectories.
Planets in the Savannah likely followed disk-driven migration, a gentler process that preserves atmospheres and maintains stable orbits, leading to longer planetary lifespans in this distant region.
