Dragrath the synestia hypothisis is interesting and may be accepted There are the outliers: Venus backwards, Uranus on it side, us with a large moon, and the double dwarf planet Pluto - Charon L O L We need giant telescopes (interferometers) in space to study other solar systems. So...

The 0° longitude gap and the absence of recorded impacts near the poles are artifacts of the observing system . . . they simply did not look there. Please refer to https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20150021386.pdf Thanks to spareine for finding the document BTW, your...

Berzie, The tilt of the Moon's orbital plane may be a matter of luck, especially if the Moon formed from the splash from a collision of a Mars sized proto-planet with the proto-Earth and the collision occurred off center. I've read something about why there are so many maria on the near side...

sophiecentaur and Eric Bretschneider Indeed, the Earth has a negligible shielding effect concerning impacts on the Moon. Check my earlier post and the post by spareine. No impact were recorded at the central meridian or the poles because they didn't look there. Here's...

Well, thanks. We'll do what we can.

Gfellow, spareine, and all, Indeed, the report spareine referenced explains the central gap and that there are no impacts recorded near the poles . . . they were not looking there. Here's a collage of screenshots from the NASA video I referenced . . . the Field of View just includes less than...

I'm retired . . . never really used my M.S. in Physics. My minor was computer science and the most I did with that was work for McDonnell Douglas on the computer controlled test set for the cruse missile. We worked in FORTRAN - yes, I'm that old. I was born before the U. S. A. went to fight...

Gentlemen Starting at 18 seconds the video shows several recorded impacts and then discusses the largest, the ~ 5 kiloton TNT equivilant meteor impact of 17 Mar2013 3h 50m 542.7s Please consider this simple explanton of the central gap and that there were no observatons of impacts at the...
