  The aim of this work is to highlight the crucial role that orbital resonances
associated with solar radiation pressure can have in Low Earth Orbit. We review
the corresponding literature, and provide an analytical tool to estimate the
maximum eccentricity which can be achieved for well-defined initial conditions.
We then compare the results obtained with the simplified model with the results
obtained with a more comprehensive dynamical model. The analysis has important
implications both from a theoretical point of view, because it shows that the
role of some resonances was underestimated in the past, but also from a
practical point of view in the perspective of passive deorbiting solutions for
satellites at the end-of-life.
