Kapan memakai Stellar Parallax 3D Explorer
Use this explorer when you want to see how the nearest stars distances are measured directly, and skip it when you want brightness-based distances or motion redshift.
- Classroom demos of parallax and the parsec
- Showing why closer stars shift more against the background
- Introducing the first rung of the cosmic distance ladder
This is an educational visualization with a hugely exaggerated parallax angle, not to scale.
