What is GAIA Atlas?
Gaia Atlas is a local stellar map tool that allows users to explore our stellar neighborhood and plan interstellar travel using realistic recreations of our star system based on GAIA DR3 mission data. The web-based visualization platform enables users to visit dozens of named stars, view exoplanet systems, and learn about stellar characteristics in an interactive 3D interface.
Key features include interstellar travel planning with realistic travel time calculations, the ability to generate shareable links to specific views or courses, options for constellations and grid overlays, accurate orbit scaling, and real orbit visualization. The tool includes a travel calculator and home button for easy navigation, along with detailed stellar information showing distance from Sol, zoom distance, spectral class, mass, and radius for each star.
Gaia Atlas is designed for astronomy enthusiasts, science fiction fans (particularly Project Hail Mary readers/viewers), students learning about stellar navigation, and anyone curious about interstellar travel possibilities. It serves as an educational tool for understanding our cosmic neighborhood and the vast distances between stars.

Frequently asked questions about GAIA Atlas
What data source does Gaia Atlas use?
Gaia Atlas uses the GAIA DR3 dataset from ESA's Gaia mission, which maps over 1.8 billion stars in the vicinity of the Milky Way galaxy with numerous measurements and stellar characteristics.
Can I plan interstellar travel routes?
Yes, Gaia Atlas allows you to plan interstellar travel with realistic travel time calculations. You can plot courses between stars, such as the example course from 61 Cygni showing travel distances and times.
How do I share what I find in Gaia Atlas?
You can generate shareable links to specific views or interstellar courses. The URL includes parameters for start star, destination distance, and other view settings that others can use to see exactly what you found.
What stellar information is displayed?
For each star, Gaia Atlas displays system name, distance from Sol in light years, zoom distance, spectral class (like G2V for the Sun), mass in solar masses (M☉), and radius in solar radii (R☉).
Can I view exoplanet systems?
Yes, Gaia Atlas allows you to view exoplanet systems and see planets orbiting other stars, including details about their orbital characteristics.
Is there a mobile app for Gaia Atlas?
No, Gaia Atlas is a web-based tool that runs in your browser. There is no dedicated mobile app, but it should be accessible from mobile browsers.
What visualization options are available?
Options include toggling constellations on/off, showing a grid overlay, enabling accurate orbit scale, activating real orbit animations, using the home button to return to Sol, and accessing the travel calculator.
How do I control the camera view?
You can drag the map to control the camera direction and use the mouse wheel to zoom in and out. Clicking on named stars like 'TAU CETI' or 'SOL SYSTEM' will automatically zoom to those locations.
Is Gaia Atlas related to the Project Hail Mary star map?
Yes, Gaia Atlas is an expansion of the original recreation of the Project Hail Mary star map. It was built using the same GAIA DR3 dataset and extends the concept with more features and stars.
What is the galactic view option?
The 'GALACTIC' view pulls the camera back to show the entire galaxy, providing context for where local stars fit within the broader Milky Way structure.
