How to Explore Meteor Airburst Size Comparison 3D Explorer

Reviewed by

Open the Meteor Airburst Size Comparison 3D Explorer, click each of the three case buttons in turn, and watch a falling entry trail replay into each case's real published altitude.

  1. Open https://freetoolonline.com/space-3d/meteor-airburst-size-comparison.html and wait for three markers to paint on the shared altitude column.
  2. Click "Chelyabinsk" (selected by default) to watch the trail fall to about 23.3 km and read its 440-500 kiloton estimate.
  3. Click "Tunguska" to watch the trail fall higher, near 7 km, and read its far larger 3-30 megaton estimate.
  4. Click "Small bolide" to see the smallest marker sit in the 20-45 km band typical of the CNEOS catalogue.
  5. Read the comparison table in the facts panel for all three cases' size, energy, and altitude side by side.
