Question grep -- clarification

Hi, I have a file which contains below info :

$ cat test_file
kenny
denny
kite

I want to get all th file names which starts with k. Hence i used below command but the result was not up to the mark :

$ grep 'k*' test_file
kenny
denny
kite

Can someone please explain me why this is behaving like this. Why it is giving 0 or more occurances when it should give 1 or more occurances ??

Waiting urgently ...

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
