freetoolonline.com editorial team
Use this explorer when you want the velocity-based tilt of starlight, and skip it when you want the distance-based parallax wobble or the long-term proper-motion drift.

| Constant of aberration | About 20.5 arcseconds (Earth ~29.8 km/s) | Static diagram without yearly ellipse scrub |
- Explaining why a finite light speed plus Earth motion tilts every star
- Contrasting aberration (same for all stars) with parallax (distance-based)
- Telling the story of Bradley proving Earth moves in 1728
This is an educational visualization with a hugely enlarged ellipse, not to scale.
