AB The existence of meteoroid streamscontaining meter-sized meteoroids capable of produc-ing meteorites after atmospheric interaction was pro-posed quite recently [1]. Their existence has importantimplications because they can be naturally deliveringto the Earth different types of rock-forming materialsfrom Potentially Hazardous Asteroids (PHA).The recent identification of Near Earth Object(NEO) asteroid 2002NY40 as source of meteorite-dropping bolides [2] opens new questions on the na-ture of this asteroid, and the physical process thatoriginated the fireballs detected in 2006 August. Twoof the fireballs exhibited a clear similarity with theorbit of 2002NY40, while a third meteoroid was hav-ing an orbit close to NEO 2004NL8. In fact, these fivebodies would be related by the close similarity amongtheir orbits (Figure 1, and Table 3 of [1]). We try tofocus here on the possible origin of this complex ofbodies on the basis of our present (little) knowledge onthe structure and orbital evolution of asteroids2002NY40 and 2004NL8.
