There are three galaxies available in Petit Planet right now, and more are on the way. Each one feels completely different from the last. If you want to know which galaxy you should choose first, this guide covers every Petit Planet galaxy, with their terrain and climate, too!
What Are Galaxies in Petit Planet?
Galaxies are the main regions of Starsea, the vast space you travel through in Petit Planet. Each galaxy is made up of its own cluster of planets that you can visit and explore. You travel between these galaxies using Starsea Voyages, which are basically your space trips across the game world. Depending on which galaxy you depart from, you'll run into different Islets, Neighbors, and scenery along the way.
Here's a quick look at all the galaxies currently in the game:
| Galaxy | Icon | Terrain | Climate |
|---|---|---|---|
| Hexia | ![]() | Verdant Plains | Warm and Humid |
| Taffeh | ![]() | Golden Prairies | Hot and Dry |
| Norvanya | ![]() | TBA | TBA |
Petit Planet is still growing, and new galaxies will be added to Starsea over time. Keep an eye on this page, we'll add each new galaxy here as soon as it's available, including terrain, climate, and all the neighbors you can meet.
Petit Planet Galaxy Index
Here is the complete breakdown for all the galaxies available in the game:
1. Hexia Galaxy
Hexia is the lush, green galaxy in Petit Planet. Its planets are full of open fields, velvet hills, and rivers, giving everything a calm and cozy feel. If you like simple, peaceful places with lots of greenery, Hexia will likely be your top pick.

The game mentions that when you travel from Hexia on a Starsea Voyage, you might pass by small bamboo islets where leaves drift in the wind. You could also come across rice field islands with a soft, natural atmosphere. The trips from Hexia feel slow and relaxing, matching the overall vibe of the galaxy.
These are the neighbors you can meet in the Hexia galaxy:
| Name | Image | Role | Birthday |
|---|---|---|---|
| Dorjelang | ![]() | Hatmaker | May 2 |
| Isaki | ![]() | Battle Beetle Trainer | July 22 |
| Yunguo | ![]() | Cultivator | September 19 |
2. Taffeh Galaxy
Taffeh is a hot and dry galaxy, but it still looks stunning. Its planets have yellow grasslands and tiered sandstone cliffs that glow gold when the sun sets. If Hexia is the farming galaxy, Taffeh is the adventurer's galaxy.

Starsea Voyages from Taffeh are just as exciting as the planet itself. You might spot dragon blood trees, or you could suddenly find yourself in the middle of ancestral cornfields.
These are the neighbors you can meet in the Taffeh galaxy:
| Name | Image | Role | Birthday |
|---|---|---|---|
| Msafiri | ![]() | Adventure Guide | August 8 |
3. Norvanya Galaxy
Norvanya is the most mysterious of the three galaxies right now. Unlike Hexia and Taffeh, during the beta test, Norvanya doesn't have a publicly listed terrain or climate yet, so its full details are still being uncovered. What we do know is that it has its own set of neighbors already living there.

These are the neighbors you can meet in the Norvanya galaxy:
| Name | Image | Role | Birthday |
|---|---|---|---|
| Frostia | ![]() | Mystic Scholar | September 9 |
| Medowlyn | ![]() | Plushie Designer | July 5 |
For now, all three galaxies bring something different to Petit Planet, and eventually you'll want to visit every single one. As more galaxies open up in Starsea, this guide will keep growing, too, so bookmark it and check back whenever a new one drops.
