# Create array @hosts... So far so good.
my @hosts=qw( lunar solar venus mars saturn pluto );
# \@hosts creates a reference to @hosts. You just want @hosts.
#
# The way you've written it, the elements in @hosts will be
# assigned to the special variable $_. This is all right, but
# tends to get confusing, especially for non-veterans. It may
# even cause problems down the line if you forget you are
# already using $_ and nest another loop that uses it. Instead
# try declaring your variable as I show below.
#
# Also foreach -> for. I think it reads better.
#
for my $host (@hosts) {
# system("/usr/bin/ssh @hosts $ARGV[0]");
# @hosts is still the array. You want $_ or $host, see above.
system("/usr/bin/ssh $host $ARGV[0]");
