Stellar Proper Motion 3D Explorer vs alternatif
This explorer shows stars drifting across the sky over millennia - Stellar Parallax 3D shows the tiny yearly wobble from Earth orbit; Star Trails 3D shows the nightly arcs from Earth spin.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| Stellar Proper Motion 3D (this page) | Real star drift over ~100,000 years | Free, in browser | Schematic, not to scale |
| Stellar Parallax 3D sibling | The yearly parallax wobble | Free web | Not the long-term drift |
| Star Trails 3D sibling | Nightly arcs from Earth rotation | Free web | Not the stars own motion |
