Como explorar Aberration of Starlight 3D Explorer

Open the explorer and watch a star tilt toward Earth direction of travel and trace its yearly ellipse.

  1. Open https://freetoolonline.com/space-3d/aberration-of-starlight.html and wait for the scene.
  2. Watch the yellow star nudge away from the white cross (its true mean position).
  3. Check the small inset - the nudge points along Earth velocity arrow.
  4. Slide the star latitude from 0 (a line on the ecliptic) to 90 (a circle at the pole).
  5. Press Play to sweep the year, and read the facts panel for the 20.5 arcsec constant.
See four Aberration of Starlight steps: open the explorer, watch the star nudge, check the velocity inset, and slide latitude.
Open the explorer, watch the nudge, check the velocity inset, then slide latitude 0-90.
