Some comparisons have been made however. Supposedly, there are substantial differences between levels of deuterium in comets and Earth's ocean water. Back when water was consider a rare commodity in the solar system, I suspected that comets got their water from Earth as they approached the Sun. (They use the water and other jetted materials for a temporary insulation of the main body.) Since Titan and other small bodies further out there contain water, it will be interesting if it is found any relationship that comet water and any of them.
