Hi, I built this and want to share some background:
Each data point corresponds directly to a real meteor entry into the Earth's atmosphere recorded by NASA CAMS (http://cams.seti.org http://cams.seti.org). Using this network of cameras, we can capture enough information about a meteor to compute its orbit around the sun. That means each particle has unique orbital parameters that accurately reflect a former meteorite in space.
In order to visualize the cloud, the epoch of these orbits is randomized. In other words, each particle begins at a random location in its orbit. This is done so the visualization can be continuous rather than only showing a clump of meteors from ~2012-2018.

- stblack 8y agoThis is extraordinary, Ian. Keep doing what you do :-)
- mirimir 8y agoI'm guessing that this uses WebGL. Yes?
- typpo 8y agoYes, that's right! Specifically, it uses three.js: https://threejs.org/ https://threejs.org/
- goodcanadian 8y ago<pedantic> A meteorite is an object that hits the ground. A meteor burns up on the atmosphere. When they are still in space and only potential meteors/meteorites, they are called meteoroids. </pedantic>
- typpo 8y agoYup, I realized this mistake after I posted but the edit option was not available.
