This month, six planets in the solar system — Mars, Jupiter, Uranus, Venus, Neptune and Saturn — will appear in Earth's skies in a "parade of planets."
Although the dark hours of Jan. 25 will be a good time to see it, as various media outlets have publicized, this sight will not be restricted to one or two nights. It will be possible to see a giant arc of planets any clear night in January (and it was visible in December, too). And, in fact, an even greater opportunity lies in the months ahead, when yet another planet joins the "parade."
