The Deepest Hole Ever Drilled Reached 0.19% of the Way to Earth’s Centre

CalculateQuick:

Source: Kola Superdeep Borehole depth from Popov et al. (1999). Earth radius and internal layers from NASA and USGS. Eiffel Tower height: 330 metres. Tools: Python with Pillow. The Earth cross-section uses an exact radial scale. At full 5400 px resolution, the true scale borehole depth is 3.46 px. The borehole is approximately 37 Eiffel Towers deep. If Earth were reduced to 1 metre wide, the hole would be 0.96 mm deep.
