In the era of precision cosmology it is essential to determine the HubbleConstant with an accuracy of 3% or better. Currently, its uncertainty isdominated by the uncertainty in the distance to the Large Magellanic Cloud(LMC) which as the second nearest galaxy serves as the best anchor point of thecosmic distance scale. Observations of eclipsing binaries offer a uniqueopportunity to precisely and accurately measure stellar parameters anddistances. The eclipsing binary method was previously applied to the LMC butthe accuracy of the distance results was hampered by the need to model thebright, early-type systems used in these studies. Here, we present distancedeterminations to eight long-period, late- type eclipsing systems in the LMCcomposed of cool giant stars. For such systems we can accurately measure boththe linear and angular sizes of their components and avoid the most importantproblems related to the hot early-type systems. Our LMC distance derived fromthese systems is demonstrably accurate to 2.2 % (49.97 +/- 0.19 (statistical)+/- 1.11 (systematic) kpc) providing a firm base for a 3 % determination of theHubble Constant, with prospects for improvement to 2 % in the future.

An eclipsing binary distance to the Large Magellanic Cloud accurate to 2 per cent
