Spherical meteoroids orbiting the Sun experience orbital decay due to the Poynting-Robertson effect and can become trapped in commensurability resonances with a planet .
Detail conditions for trapping in the planar circular restricted three-body problem with action of solar electromagnetic radiation on spherical grain are presented .
The results are given in terms of the radiation presure factor \beta .

In general , the greater value of \beta , the shorter capture time in a resonance .
Captures of particles may be even several times longer than it is presented in literature .
Analytical formula for maximum capture times is given .

Analytical theory for minimal capture eccentricities is presented .
The obtained analytical results differ from those presented in the literature .
However , the known analytical results are not very consistent with our detail numerical computational results for \beta - values 0.01 and 0.05 and for the planet Earth .
Minimum eccentricities for captures into resonances are also smaller , even in order of magnitude , than the published values .

The presented results enable comparison with calculations for nonspherical particles .
