    Abstract

    Recently a new unexpected population of 10 cm size space debris near the geostationary orbit (GEO) has been discovered. These objects with high area-to mass ratios sometimes present highly eccentric orbits (Schildknecht et al., 2004, 2005). Recent numerical and analytical investigations (Anselmo & Pardini, 2005; Liou & Weaver, 2005) prove that this newly discovered population consists of near geosynchronous objects with high area-to-mass ratios. The large area-to-mass ratios space debris have a dynamical behavior dominated by the solar radiation pressure and the resonance with C_22 spherical harmonic. In this paper we develop further the analysis done by Valk et al. (2008) by using a frequency analysis to study both the stability and the resonances of such particular orbits.
