Which of the two astronomical phenomena – the tangential covering of the star by the Moon or the tangential covering of the planet by the Moon – is one of the most interesting astronomical phenomena for science and why?

Tangent star coverage. At this time, the star can appear and disappear several times behind the lunar mountains. His observations allow us to study the movement and shape of the moon. And when the planet is tangentially covered, we can observe only a partial closure of its disk.
