The Moon's gravity is uneven due to its irregular shape and varying density, which cause gravitational anomalies across its surface. Similar to Earth, the gravitational pull on the Moon is influenced by its topography and the distribution of mass within it. Variations in the Moon's crust thickness and the presence of large impact craters also contribute to these gravitational differences. Understanding these gravitational variations offers insights into both lunar geology and the dynamics of celestial bodies. The discussion highlights the importance of detailed explanations and research when exploring gravitational phenomena.

Why is the moon's gravity so uneven?...give detailed explanation...
Partial solar eclipse from Twizel, South Isl., New Zealand ...
almost missed it due to cloud, didnt see max at 0710 NZST as it went back into cloud.

Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed).
n.b. I start this...
Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons.
Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
