What's Missing?
The brightest objects in an exoplanet's sky would be:
- Other stars in multiple star systems
- Other planets in the same star system
- Moons orbiting the exoplanet itself
These aren't included - yet.
Alpha Centauri
Where is it? I'm still deciding how to make Alpha Centauri fit. Right now, you can find Rigel Kentaurus (Alpha Centauri A) and Toliman (Alpha Centauri B). It's a triple star system that you can distinguish the brightest two with low power binoculars, and so they have their own names. All other binary/triple systems are treated as one star here for now.
Notes
Know something I don't? If you're visiting from one of these systems and notice something's off, let me know. Telepathy sometimes works, or you can find me in the redwoods of Mendocino County, California.
Performance

Constellations
Fun fact: Constellation lines from distant vantage points look less like familiar patterns and more like jumping to lightspeed. But hey, it's fun!
However, check out what Orion looks like from here, Sirius, Procyon, and Altair:

How about galaxies?

What about our universe?

What are your data sources?
How did you make this?
I used python, vscode, astropy, and a lot of coffee. Wrote python scripts to generate skies from different star systems, then rendered them with three.js. So, python scripts that grab raw data, generate html, css And javascript to work with three.js.
