Re: Terminal Velocity of Impacting our Moon

Terminal velocity, to my understanding, is a *constant velocity*
resulting from the equilibrium of a force such as gravity and the
drag of a resisting medium, such as a planet's atmosphere.

Are we on the same page?
Sam Wormley,
Keep a good hold onto that constant velocity notion (w/o thrust
applied), replace whatever's your atmospheric density with whatever's
of SM or ISM, increase that wishful velocity factor up to 10%'c'(30,000
km/s) and utilizing stellar gravity instead of merely local gravity is
what should keep us at least within the same footnotes of that very
same page.

Remember that such fewer atoms of the SM or ISM do have some room to
give a little without their significantly packing too much into one
another. However, the forward compression wave is likely going to
become somewhat of a thicker soup that's taking up volume and
unavoidably demanding of energy as it represents an extra amount of
drag coefficient.

Interesting in how you're so good at intentionally dragging this one
out. Is it something I said that's supposed to remain as
nondisclosure?

Are you afraid to stipulate or even shy as to speculate as to what such
a javelin impactor might have to deal with? or of whatever a
interstellar probe has to overcome if making such horrific velocity as
10%'c'?

If you'd like to include a consideration for the lunar atmospheric
terminal velocity, whereas starting in at LL-1 that's perhaps offering
us as few as 100 atom/cm3 while we're situated at 34.37r, and obviously
dramatically increasing in population density/cm3 with every closing
km, then picking up a few extra atoms of sodium from the distance of
9r(15,642 km) seems fairly obvious (actually there's also the fairly
substantial [moon sized] sodium cloud that's worth potentially on
average hundreds of those sodium atoms/cm3, that's trailing a good
900,000 km stream as continually blown away from our salty moon by the
solar wind), and then essentially following the expected increase as
per getting closer to the moon until eventually there's millions upon
millions of those various atoms/cm3 to work with, many of which holding
nearest the surface being the likes of argon and radon.
