Asteroid Discoveries 1980-Present

Where I work, there is an ongoing debate about the relative merits of actual measurements and statistical modeling.  Measurements tell you what’s _actually_ going on in reality, but in terms of time and money, it’s expensive.  Statistical modeling is faster and cheaper, but less accurately describes what’s _actually_ going on in reality.

I think this video demonstrates one instance of a seamless blend of measurements and modeling.

[…] asteroids that were discovered from 1980 to 2010 appear in the sequence as they were discovered.

Note that a new pattern emerges in 2010,

with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that’s tasked with imaging the entire sky in infrared wavelengths.
