Which has a greater gravitational pull on me: the Sun, or spiders?
Granted, the Sun is much bigger, but it is also much further away,
and as I learned in high school physics, the gravitational force is
proportional to the square of the distance. — Marina Fleming
One could argue that the true gravitational force is the tidal spaghettification force which drops off as the cube of the distance. This drop-off nicely cancels the mass/volume growth of large distance objects like the Sun such that the the tidal spaghettification forces of the (apparent) equal sized Sun & Moon are comparable (except for the fact that the Moon is somewhat denser).
Hence, if a thread dangling spider is close enough to you to block out the Sun (or Moon) then the gravitational tidal spaghettification force on your head due to that spider exceeds that of the Sun (or Moon).
