You are not giving scp a host to connect to, so you are in effect
coping /etc/hosts on the local machine to /etc/hosts on the local
machine. Try something like:

for i in orion earth ; do scp /etc/hosts $i:/etc/hosts ; done

I tend to be conservative, and specify the entire file name for the
target. It isn't required in this case, but I like to play it safe.
In order for this to work, you need to have your public key in
/root/.gnupg on the target machines. You have to have the key
unlocked, or not have a pass phrase. The script also has to be run
as root.

If you want to run the script as a normal user, you can use:

for i in orion earth ; do scp /etc/hosts root $i:/etc/hosts ; done
