A great tool to fill an untapped niche in world building groups. It's fun and pretty intuitive to use, and the music is great for a little background melody, the whole thing just feels good to use. The developer is active over on the community discord and open to ideas and feedback. If you're neck deep in sci-fi world building like I am then this could be a must have for you.

About This Game
Whether you are running a space based table top campaign and need a place to track the worlds your players visit, want to visually share the universe you created for them to play in, or want to track your observations of our night sky and imagine what could be out there, Stellar Navigator has you covered!
Stellar Navigator provides a unique toolset which allows you to build your dream galaxy and all the solar systems therein. You choose how to light up the night sky!
Craft a unique galaxy

Why stop at one solar system? Fill an entire galaxy! In the galaxy view, additional details may be added to each solar system and the background image and overlay can by modified.
Give life to your solar systems
Solar Systems
Add planetary bodies, moons, asteroids, black holes, and comets to each solar system and mark them up with the label system and markers. Or modify the asteroid belt's size scale and distance from its star.
Planets
Stellar Navigator offers creators the ability describe each of their planets and add planetary properties to further set worlds apart. These properties include:
The visual type of the planet
Biomes which are present on the planet
Elements (both known elements and the ability to create your own!)
Natural Satellites
Gravity
Temperature
Atmosphere
Day length
Tabletop
Export images with square or hexagonal grid overlays (or none) in a landscape or 1:1 layout for table top space combat games. Stellar Navigator also comes with a system tour mode that can run quietly in the background as a visual aid during your tabletop game sessions.
Additional Features & Support
Stellar navigator has been built to be used on small format screens as well as ultrawide monitors (E.g., 32:9 aspect ratio).
