Humanity has been on an asteroid-finding spree as of late.
Those close to Earth, known as Near Earth Objects , have been particularly interesting for two reasons.mining. The other is they are potentially devastating if they hit the Earth, so we'd like to find them with some advance warning.
Of the 30,000 total NEOs found so far, about 2,300 of them are PHAs. However, researchers think there are at least that many left to be discovered. PHAs typically come within 5 million miles of Earth and must be large enough to be a potential threat, not just burn up in our atmosphere as a shooting star.
That's where the new algorithm comes in. Developed by Ari Heinze, a researcher at UW, and Siegfried Eggl, now a professor at the University of Illinois Urbana-Champaign, the algorithm, known as HelioLinc3D, is capable of finding data on asteroids that might be spread throughout observations of multiple days from a single satellite.
