<p>The moon at apogee and heading south.</p><p>Uranus goes retrograde.</p><p>Mercury moves toward Venus.</p><p>What&#39;s in a name? Maybe a few thousand years of human oral history. It doesn&#39;t seem so now, but <em>Milky Way</em> and <em>galaxy</em> go back to the same origin when people described what they saw in the sky.</p>
