Hello dear student,
Greetings,
I think it's a question from physics and you want to ask something regarding distance of closest approach or something like that , but your question is not clear in its meaning,  I am not able to understand what exactly you want to ask ; so kindly repeat your question again correctly so that I can help you.
Thankyou
Good luck
