This work is about neutron astronomy. The registration of high energy neutrons can be used to investigate gas and dust components of the Kuiper belt. A new method for studying the diffuse matter in space based on observing high_energy neutrons is analyzed. The high_energy neutrons (with energies of hundreds of Gev) can travel distances comparable to the distance between the Earth and the Kuiper belt. A background of neutrons (at these energies) from beyond the Solar System is limited by decay. It is shown that the expected flux of high_energy neutrons can be recorded by facilities using the data on the density of the gas and dust component obtained when analyzing the trajectories of space probes.
