We study the capillary rise of wetting in liquids by slightly modifying Ponomarenko’s result, a recently derived and observed t^1/3 law, without omitting the corresponding gravity term and therefore we find h_new (t)≅0.9085h_Pon (t) instead, which corresponds to a 9% difference. Furthermore, in order to examine the effect of corrected gravity, we extend the result on the surface of a planetary body by correcting the gravitational acceleration for its oblateness coefficient and rotation. We find that experiments that take place on the equator result in highest capillary heights, than those at mid latitudes and the poles. …
