Algorithm Identifies “Potentially Hazardous” Asteroid

It poses no danger to Earth for the foreseeable future.


A breakthrough in asteroid discovery has taken place, with an algorithm identifying a “potentially hazardous” asteroid designated 2022 SF289. Identified by the HelioLinc3D algorithm during a test drive with the ATLAS survey in Hawaii, this marks a significant step toward enhancing our understanding of near-Earth objects (NEOs).

Algorithms, Asteroids, and More

The next-generation algorithm, HelioLinc3D, allows scientists to identify near-Earth asteroids with fewer observations. This improves our ability to track these objects and increases our safety. Ari Heinze, the principal developer of HelioLinc3D and a researcher at the University of Washington, states that this discovery will lead to the identification of thousands more unknown potentially hazardous asteroids.

A Glimpse into Our Solar System’s Past

The solar system harbors millions of rocky bodies, relics of an era over four billion years ago. Some of these objects orbit close to Earth and demand special attention, known as “potentially hazardous asteroids” (PHAs). These are systematically searched for and monitored to ensure Earth’s safety.

Set to begin operation in early 2025, the Vera C. Rubin Observatory will increase the discovery rate of PHAs dramatically. Using an 8.4-meter mirror and a massive 3,200-megapixel camera, Rubin’s advanced technology requires a new algorithm to spot space rocks reliably.


HelioLinc3D: Testing the Waters

With Rubin still under construction, researchers wanted to test the new code on existing data. They managed to spot the PHA 2022 SF289, initially imaged by ATLAS, successfully showcasing the capabilities of the new algorithm.

Classified as an Apollo-type NEO, 2022 SF289’s closest approach brings it within 140,000 miles of Earth’s orbit. However, it poses no danger to Earth for the foreseeable future. This discovery illustrates the potential of the new algorithms and telescopes in detecting these elusive objects.

The Future of Asteroid Discovery

According to Rubin scientist Mario Jurić, this is just a preview of what’s to come. With the Rubin Observatory launching soon, the next decade of discovery will be marked by advancements in algorithms as much as in new, large telescopes.


The discovery of 2022 SF289 is more than just a scientific achievement. It’s a step towards enhancing our ability to identify and monitor potentially dangerous celestial objects. With new algorithms like HelioLinc3D, we are better equipped to keep an eye on our cosmic neighborhood and ensure our planet’s safety.
