The discovery of 2022 SF289 marks a significant milestone in data-intensive astronomy and highlights the potential of the HelioLinc3D algorithm. This next-generation software will be crucial for the Vera C. Rubin Observatory’s upcoming Legacy Survey of Space and Time, which aims to uncover thousands of yet-unknown potentially hazardous asteroids.
Potentially hazardous asteroids, or PHAs, are objects that have the potential to make threatening close approaches to Earth. While 2022 SF289 poses no immediate risk, its discovery demonstrates the effectiveness of HelioLinc3D in identifying near-Earth asteroids with fewer and more dispersed observations than current methods require.
The solar system is home to millions of rocky bodies, ranging from small asteroids to dwarf planets. Near-Earth objects, or NEOs, are a subset of these bodies that orbit close to Earth. PHAs, in particular, warrant special attention as they have trajectories that bring them within about 5 million miles of Earth’s orbit.
Scientists search for PHAs using specialized telescope systems like the NASA-funded ATLAS survey. By taking images of the sky multiple times each night, they can identify moving objects that may be potential threats. However, current methods have limitations, and it is estimated that there are many more PHAs yet to be discovered.
The Vera C. Rubin Observatory, set to begin operations in early 2025, will significantly increase the discovery rate of PHAs. With its advanced technology, including an 8.4-meter mirror and a massive 3,200-megapixel camera, Rubin will scan the sky at an unprecedented speed. However, this requires a new type of discovery algorithm to effectively identify space rocks.
The HelioLinc3D algorithm, developed by the solar system software team at the University of Washington’s DiRAC Institute, fills this need. Working with renowned astrophysicist Matthew Holman, the team created a code that could find asteroids in Rubin’s dataset. To test its effectiveness, the team used data from the ATLAS survey and successfully discovered 2022 SF289.
2022 SF289, classified as an Apollo-type NEO, has a diameter of 600 feet and comes within 140,000 miles of Earth’s orbit, closer than the moon. Despite its classification as “potentially hazardous,” projections indicate that it poses no immediate danger to Earth.
The discovery of 2022 SF289 is just the beginning for HelioLinc3D. In less than two years, when the Rubin Observatory is fully operational, the algorithm will be discovering objects like this on a nightly basis. This represents a new era of data-intensive astronomy, where advancements in algorithms and technology will unlock the mysteries of the universe.
With the potential to uncover thousands of yet-unknown PHAs, the Vera C. Rubin Observatory and the HelioLinc3D algorithm are crucial for ensuring the safety of our planet and advancing our understanding of the solar system.HelioLinc3D, a cutting-edge asteroid discovery algorithm developed for the Vera C. Rubin Observatory’s upcoming sky survey, has achieved a significant milestone by identifying its first “potentially hazardous” asteroid. The asteroid, named 2022 SF289, was discovered during a test run of the algorithm with the ATLAS survey in Hawaii. This breakthrough marks a promising advancement in near-Earth asteroid detection and highlights the potential of data-intensive astronomy.
Potentially hazardous asteroids (PHAs) are objects that have the potential to make threatening close approaches to Earth. The discovery of 2022 SF289 confirms that HelioLinc3D can identify near-Earth asteroids with fewer and more dispersed observations compared to current methods. This software will be crucial for the Vera C. Rubin Observatory’s Legacy Survey of Space and Time, which aims to uncover thousands of yet-unknown PHAs.
Ari Heinze, a researcher at the University of Washington and the principal developer of HelioLinc3D, emphasized the importance of this discovery in ensuring the safety of our planet. “By demonstrating the real-world effectiveness of the software that Rubin will use to look for thousands of yet-unknown potentially hazardous asteroids, the discovery of 2022 SF289 makes us all safer,” Heinze stated.
The solar system is home to millions of rocky bodies, ranging from small asteroids to dwarf planets. Near-Earth objects (NEOs) are a subset of these bodies that orbit close to Earth. PHAs, in particular, require special attention as they have trajectories that bring them within approximately 5 million miles of Earth’s orbit. Scientists systematically search for and monitor these PHAs to prevent potential collisions with Earth.
Specialized telescope systems like the NASA-funded ATLAS survey are used to search for PHAs. These systems capture images of the sky multiple times each night, and a discovery is made when a point of light is observed moving in a straight line. So far, approximately 2,350 PHAs have been discovered using this method, but scientists estimate that there are many more waiting to be found.
The Vera C. Rubin Observatory, located in the Chilean Andes, will join the search for PHAs in early 2025. With its advanced technology, including an 8.4-meter mirror and a massive 3,200-megapixel camera, Rubin will significantly increase the discovery rate of PHAs. The observatory will scan the sky at an unprecedented speed, visiting spots twice per night instead of the four times required by current telescopes. To effectively spot these space rocks, a new type of discovery algorithm, such as HelioLinc3D, is needed.
The team at the University of Washington’s DiRAC Institute has been working on developing such algorithms. HelioLinc3D, created by Ari Heinze and Siegfried Eggl, successfully identified 2022 SF289 in existing data from the ATLAS survey. This asteroid had previously gone unnoticed due to insufficient observations. HelioLinc3D was able to combine fragments of data from multiple nights and make the discovery.
2022 SF289 is classified as an Apollo-type NEO, with a diameter of 600 feet. Although it comes within 140,000 miles of Earth’s orbit, closer than the moon, projections indicate that it poses no immediate danger. The discovery of 2022 SF289 has been announced in the International Astronomical Union’s Minor Planet Electronic Circular.
The Rubin Observatory’s upcoming sky survey, combined with advanced algorithms like HelioLinc3D, will revolutionize the field of data-intensive astronomy. Mario Jurić, director of the DiRAC Institute, highlighted the significance of these advancements, stating, “It’s a preview of the coming era of data-intensive astronomy. From HelioLinc3D to AI-assisted codes, the next decade of discovery will be a story of advancement in algorithms as much as in new, large telescopes.”
The financial support for the Rubin Observatory comes from the U.S. National Science Foundation, the U.S. Department of Energy, and private funding raised by the LSST Corporation. With the continued development of advanced algorithms and the capabilities of state-of-the-art observatories, scientists are poised to make groundbreaking discoveries in the field of astronomy.
