The Google Earth package is available on the Packman repos or you may download the relevant RPM file from http://www.google.com/earth/download/ge/agree.html.
To download & install from the repos, do:
zypper in google-earth-stable
To install the downloaded RPM file from Google, do:
rpm -ivh google-earth-stable_current_x86_64.rpm
On my laptop I had issues running Google Earth as libGL.so.1 was missing. You may resolve this by installing the libGLEW1_6-32bit package.
zypper in libGLEW1_6-32bit
Once everything is in place, you may get Google Earth up and running.
