Ryugu (think asteroid hoppers) - Hayabusa2 was unsuccessful in looking for any at L5, on its way to Ryugu

planetoids? protoplanets? planetismals?

4.5 billion years ago (give or take) there were lots of collisions... Mars is not properly round; Mercury is too dense and metallic - probably an impact knocked away most of its crust and mantle, which ended up on Venus (possibly even Earth); Venus was hit by such a huge impact, it now spins the wrong way...

Gaia and Theia https://en.m.wikipedia.org/wiki/Theia_(planet)

Some pull from Venus or Jupiter (possibly both) grabbed Theia and sent it towards Gaia...

The impact was enough to merge the two - and then explode into a giant ring (think Saturn) surrounding the now larger mass we now call Earth - tilted to 50 or maybe even 60 degrees, and spinning so fast that a day is around 5 hours long.

That ring ("synestia") only took about a century or so to form The Moon - a quarter the size of Earth, but only one tenth its mass (made up of mostly surface/mantle materials)

https://en.wikipedia.org/wiki/Synestia

Both Gaia and Theia's cores ended up in the Earth - which is too dense for a planet this size ...

This "lost" planet is not really lost - its atoms are in every one of us

Impact craters

South Pole-Aitken basin https://en.wikipedia.org/wiki/South_Pole%E2%80%93Aitken_basin

Hang on - it's perpendicular to the solar plane... nothing but interstellar space above the south pole - so where would all those big rocks come from?

Polhode & precession

https://en.wikipedia.org/wiki/Polhode https://en.wikipedia.org/wiki/Precession

The moon has moved so far out from the Earth that the sun has straightened up its axis - making what used to be some region near its equator now its pole (it has fixed up the Earth a little too - we now only have a 23* tilt).

Libration zone so moon is tidally locked - same side always showing - BUT all orbits are elliptical... https://en.wikipedia.org/wiki/Kepler%27s_laws_of_planetary_motion

... and it rotates (one day per month)

so when it's further away it slows down and shows us a little more of its left side and then it's going faster, showing us more of its right side

(Galileo was the first to notice this - said it was like a man tilting his face while shaving)

so... everywhere else on the moon, the Earth stays in place overhead (and on the far side you never see it) - BUT in the libration zone, you get Earthrise (and Earthset)
