How to explore Meteor Shower Radiant 3D Explorer

Reviewed by

Open the Meteor Shower Radiant 3D Explorer, switch between the Perseids and Leonids, and watch parallel streaks keep one apparent radiant on the sky.

  1. Open https://freetoolonline.com/space-3d/meteor-shower-radiant.html and wait for the local sky dome and radiant ring.
  2. Read the facts panel: Perseids peak Aug 12-13, ZHR ~100, parent 109P/Swift-Tuttle.
  3. Switch from Perseids to Leonids to compare parent streams.
  4. Scrub Speed and Trail, or press Pause/Play streaks.
  5. Orbit the camera to confirm the radiant is a perspective direction, not a physical origin point.
See four steps in the Meteor Shower Radiant walkthrough: open the explorer, read the facts panel, switch from Perseids to Leonids, then scrub Speed and Trail or press Pause and Play streaks.
Open explorer, read facts, switch streams, scrub Speed Trail.
