If by chance an object did approach Earth at a slow

I thought that would depend on (aside from velocity) the size and density of
the object with regard to it's Roche Limit.
Also, because of the horseshoe orbit of Asteroid 3753, would you say that
our moon is acting as a 'Shepherd' satellite?
Just got Jarmo's message. Good points. Am going out now. Will have to
check in later.
Best regards,
