Abstract

The process of celestial object positioning is complex and time-consuming. Astronomers must choose objects of interest (asteroids or comets) and calculate precise orbital elements including eccentricity, inclination, longitude of ascending node, argument of perihelion, semi-major axis, and mean anomaly. These parameters are converted into right ascension and declination coordinates to determine exact positions, then recorded in FITS files. To streamline this process, a web application for automatic celestial object positioning has been developed. Users can upload FITS files to identify celestial objects, with the system generating annotated images showing object positions and relevant details. The system allows for easy downloading of FITS files and JPEG images for further analysis. Notably, it achieves an error rate below 0.0001% when compared to JPL Horizons, NASA's solar system data service.
