Fluid interfaces are producing several static and dynamic phenomena. These interfaces are governing, for instance, the shape of sessile droplets and the spread of liquids on surfaces. In this paper, we will discuss the shape of sessile axisymmetric drops on a solid surface and how it is depending on gravity, obtaining results that are in agreement with experimental observations under conditions of microgravity.
