摘要：We present HelioLinC, a novel approach to the minor planet linking problem. Our heliocentric transformation-and-propagation algorithm clusters tracklets at common epochs, allowing for the efficient identification of tracklets thatrepresent the same minor planet. This algorithm scales as ( ) N N log with the number of tracklets N, a significantadvance over standard methods, which scale as ( ) N 3 . This overcomes one of the primary computationalbottlenecks faced by current and future asteroid surveys. We apply our algorithm to the Minor Planet Center’sIsolated Tracklet File, establishing orbits for more than 200,000 new minor planets. A detailed analysis of theinfluence of false detections on the efficiency of our approach, along with an examination of detection biases, willbe presented in future work.
