The paper discusses an approach that made it possible to estimate thedistance to the nearest pevatrons, which form a knee in the spectrum of thecosmic ray nucleon component of about $4$ PeV. It is based on the spectra ofnucleons and electrons obtained by the authors in the framework of thesuperdiffusion model of nonclassical cosmic rays diffusion, which have a knee,on the assumption that nucleons and electrons are accelerated by the same typesources and their propagation in an inhomogeneous turbulent galactic medium ischaracterized by the same diffusion coefficient, and also on the knee in thespectrum of the electronic component in the region of $0.9$ TeV, established inthe DAMPE experiment.  It is shown that pevatrons, which form a knee in the spectrum of the cosmicray nucleon component of about $4$ PeV, are located at distances of the orderof $0.75$ kpc from the Earth.

Where are the Pevatrons that Form the Knee in the Spectrum of the Cosmic Ray Nucleon Component around 4 PeV?
