Any object that has an orbit that takes it near the Earth, but has a period the length you are thinking of would quickly be perturbed by Jupiter, because it's orbit would require it to cross Jupiter's orbit. There is a means to have an 11 year gap between falls called orbital resonance, http://en.wikipedia.org/wiki/Orbital_resonance Unfortunately, while initially resonance may make your example seem more possible, there are particulars here that make it even more unlikely... A few more terms you may want to research are orbital distribution and Kirkwood Gaps.
