# A systematic ranging technique for follow-ups of NEOs detected with the Flyeye telescope

## TL;DR

This paper presents a systematic ranging method for rapidly determining the probable sky region of newly detected near-Earth objects by ESA's Flyeye telescope, aiding immediate follow-up observations and impact risk assessment.

## Contribution

It introduces a systematic ranging approach tailored for short-arc orbit determination of NEOs detected by Flyeye, enhancing impact prediction capabilities.

## Key findings

- Effective prediction of sky regions for follow-up observations.
- Quantitative detection probability estimates.
- Assessment of suitable follow-up telescopes.

## Abstract

When new objects are detected in the sky, an orbit determination needs to be performed immediately to find out their origin, to determine the probability of an Earth impact and possibly also to estimate the impact region on Earth. ESA's Flyeye telescope is expected to revolutionize the effort of predicting potential asteroid or deep space debris impact hazards due to the expected increase of near-Earth object discoveries. As the observed orbit arc for such an object is very short, classical Gaussian orbit determination cannot be used. We adopt the systematic ranging technique to overcome the lack of information and predict a region of the sky where the body can most likely be found. We also provide a detection probability for follow-up observations and investigate potential follow-up telescopes for the Flyeye telescope.
