question about RSA

Question

I am very new in cryptography field, what I want to ask but I cannot find an answer is this: In public key cryptography, such as in RSA, does it matter if the adversary knows/can detect the public key? With only the public key, can he eavesdrop a message?

Thank you

The public key is published in public so that anyone (including attackers) can get it. The point of public-key crypto is to be able to do so without compromising security in any way.

Public key cryptography is named public because public keys are considered to be available to everyone and this alone is not sufficient to decrypt messages.
