Scientific paper

Based on an analysis of the geological history, tectonic and biotic events, climate evolution, and changes in the atmosphere, hydrosphere, and terrain, the length of the galactic year is tentatively estimated at 215 million years. Every galactic year consists of one 30-million-year cycle corresponding to the perigalacteum position of the solar system, one 85-million-year cycle corresponding to the apogalacteum position, and two medium periods lasting 50 million years each.
