Results from tests of the inverse square law (ISL). The horizontal axis is the length range over which the ISL was tested, while the vertical axis is the precision, relative to Newtonian gravity, that was achieved. Limits from laboratory, terrestrial, satellite (LAGEOS), lunar laser ranging (LLR), and planetary measurements all contribute at various length scales. (Unit: 3)
