Copy and rename files - Linux cp command

Question

I have the following files in my directory.

    tom_aaa.txt  
    tom_bbb.txt  
    tom_ccc.txt 

I want to copy these files and rename them by replacing tom with jerry using shell command (MAC / LINUX /UNIX)

Expected result:

tom_aaa.txt  
tom_bbb.txt  
tom_ccc.txt  
jerry_aaa.txt  
jerry_bbb.txt  
jerry_ccc.txt 

Any suggestions?
