Аннотация: The paper discusses an approach that made it possible to estimate the distance to the nearest pevatrons, which form a knee in the spectrum of the cosmic ray nucleon component of about <span class="mathjax-tex">\(4\)</span> PeV. It is based on the spectra of nucleons and electrons obtained by the authors in the framework of the supeПоказать полностьюrdiffusion model of nonclassical cosmic ray diffusion, which have a knee, on the assumption that nucleons and electrons are accelerated by the same type sources and their propagation in an inhomogeneous turbulent galactic medium is characterized by the same diffusion coefficient, and also on the knee in the spectrum of the electronic component in the region of <span class="mathjax-tex">\(0.9\)</span> TeV, established in the DAMPE experiment. It is shown that pevatrons, which form a knee in the spectrum of the cosmic ray nucleon component of about <span class="mathjax-tex">\(4\)</span> PeV, are located at distances of the order of <span class="mathjax-tex">\(0.75\)</span> kpc from the Earth.
