I had the same confusion so here's my layman's understanding. They are defining capture/orbit as having negative "geocentric energy" which is a term of art no one else seems to use but I think is just a mathematical representation of the following:
> a temporary satellite is any body that enters the Hill sphere of a planet at a sufficiently low velocity such that it becomes gravitationally bound to the planet for some period of time. [1]
again stretching my understanding too far, I think this basically means that in the absence of other celestial bodies the satellite would be in a stable orbit, but that in reality after some time it gets far enough away that the sun's gravitational pull dominates and stops it from making a full orbit.
> in the absence of other celestial bodies the satellite would be in a stable orbit
Presumably entering such an orbit is only possible due to forces from other celestial bodies in the first place, since otherwise if you reversed time it would spontaneously leave its orbit. In other words, the act of the earth "capturing" the object is ultimately performed by external forces?
That's like calling a lifetime lived within just one village 'temporary'. On the scale of human events it's nearly as permanent as anything else for which we commonly ascribe permanence and reliability within lifetime scales.
It's fair to describe objects in relation to the lifespans of those objects, not of those who observe. "On the scale of human events" is not the only relevant timeframe for discussing celestial bodies.
Like measurable in our lifetime? The average distance to the moon will be 3.8 meters further away in a hundred years. That's insignificant as far as tides goes.
Despite what another commenter says, the moon will not leave earths captive field. It will recede until it gets tidally locked with earth, and both the tide cycles and the moons recension will halt. That is, if there still is water in a few billion years and it hasn't been replaced with Brawndo
Is the moon not already tidally locked? The same hemisphere of it always faces the earth. Is there a different kind of tidal locking or orbital resonance it will settle into?
It goes on until an Earth's day is as long as a month. Both will face each other in a fixed way.
But it takes many billions of years and the Sun will burn both to a cinder much before that.
Because during that time from its frame of reference it will be falling around the earth until it reaches escape velocity and starts falling around the sun again.

A long time ago I read someone saying "Lisp is the only language where I spend more time thinking than typing". Recently, when I was telling ChatGPT what logic I wanted written on what data structures, I realized the same was true about having an LLM write any other language.
Honestly, to me that sounds like a red flag. There are already too many temptations to get on a purist mood and spend ages thinking about elegant code structure.
I know, it's ambiguous, "more time thinking than typing" might imply that you spend more time thinking about the core problem you are solving. But let's be real, it's Lisp, you are thinking about how to model your problem elegantly in Lisp, not about how to solve it.
This is incidental complexity, you might feel mightily smart and productive, but you are really not getting anything substantial done. Clean code is critical, but in moderation, you need to constantly prevent it from upstaging the actual problem you are working on.
Part of the Common Lisp experience is tool building at the language level.
You could be digging a hole with your hands. But thinking a moment, somebody came up with the idea of a shovel. That made a huge difference.
Similar, tool building & usage at the language level can also make a huge difference. In larger applications this makes code much more compact and makes a person more productive.
Given that fasting is enshrined as a order in many belief systems, it seems like humans needs external motivation to ignore their body's complaints and fast for positive effects.
75% of adult in the west are obese or overweight because they listen to their body...
What we call fasting today was the defacto lifestyle for hundred millions of years. The current three meals a day pattern doesn't even register on that scale
In 2005 the drummer for Semisonic wrote the book So You Wanna Be a Rock & Roll Star. In it the band received a record plaque and asked the record company rep if it was their music. The response was no, it was probably some left over Sinatra LP that had been painted.
