Abstract:
The study of Near-Earth Asteroids (NEAs) is essential in understanding Solar System evolution and planetary defence. While spectroscopy offers detailed insights, multi-band photometry provides a faster and more accessible alternative for estimating surface composition. We present early results from B, V, R, and I observations of several NEAs obtained during 2025–2026 within the NEOPOPS program [1], using the 1.2 m telescope at Observatoire de Haute Provence (France). After applying standard calibration, aperture photometry, and statistical cleaning methods, we derived color indices and converted them into reflectance spectra. These were used for taxonomic classification [2] through a probabilistic clustering method developed by Max Mahlke and collaborators [3].Out of 31 analysed objects (including 14 Potentially Hazardous Asteroids), 17 objects belonging to the S-complex (including Q class), 7 to the C-complex (including B class), 4 to the M-complex, alongside minor contributions from V and O-types.These findings support the use of broadband photometry as a practical tool for rapid taxonomic classification and physical characterization of NEAs.
