Cometary disruptions are though to be
an important source of Near Earth Objects (heareafter
NEOs). A continuous monitoring of meteor showers
from multistation networks on the ground allows to get
valuable orbital information of large meteoroids producing
fireballs. From such orbits can be established
conections with the orbital elements of diferent asteroids
or comets. In 2010 we started a program to get
precise orbital information of very bright Taurid bolides
in order to try to identify possible associations
with members of the NEO population [1]. We have
already identified some meteoroids that could be dynamically
associated with some NEOs currently identified
as members of the Taurid complex. This group of
bodies is formed by about 20 NEOs that presumably
formed by the fragmentation of a giant comet over the
past 20-30 kyr [2-4]. Some of these bodies have orbital
affinities to comet 2P/Encke, but recent studies have
found other asteroids in Apollo-like orbits that can be
good candidates to trace a progressive cometary disruption
that at different stages as a by-product produced
the Taurid meteoroid branches [3, 4]. It is important
to remark that the NEOs associated with the
Taurid meteoroid streams are presumably dark, as
seems to confirm the spectral information obtained for
the largests members (e.g. 16960 belongs to the B
spectral class [5]). Consequently these bodies are
among the most difficult and hazardous NEOs that
remain to be discovered. In fact, the Tunguska object
has been temptatively associated with the Taurid complex
[6]. A recent paper also links the Earth’s intersection
with the debris produced by the disruption of the
cometary progenitor with a possible Palaeolithic extinction
occurred around 12,900 BP [7]. Our orbital
studies of Taurid meteoroids could also identify other
members of the complex by using association criteria
and backwards integration of their orbits. In fact we
have found some Taurid complex members that are
exhibiting orbits not directly linked with the two main
branches. Obviously, having the Taurid complex some
members with about 100 meters in diameter [4], we
suspect of the existence of much more bodies in such a
range of sizes not discovered yet. These objects could
also produce meteorite-droping bolides in determinate
favourable geometric circumstances [1]
