The five brightest planets - Mercury, Venus, Mars, Jupiter and Saturn have been known since ancient times. They can easily be seen with the naked eye if one knows when and where to look. This is the best time of the year to catch the Fab Five. First try to see Mars sitting low in your eastern sky just before dawn. Mars comes up only a short while before the break of day, so you don't have plenty of time to catch it. See also Regulus and Spica, two of the brightest stars in the night sky. Four in a row after sunset That will also be a perfect evening to see Venus, Mercury, Jupiter and Saturn at the same time. Mercury and Venus are low to the west, sitting side by side. Bright Jupiter shining to the southwest, and completing the set of four is Saturn, higher up in the south southwestern sky. See also a red supergiant star sitting between the planets. This is Antares, the brightest object in the constellation of Scorpius. Of all the four planets, Mercury is the faintest and therefore hardest to see, so having bright Venus as a signpost to Mercury is always an advantage. Keep in mind, Mercury was at Greatest Eastern Elongation a few days ago, and this is the best time to observe the innermost planet. Planetary Lineup Three out of the four planets will be beautifully aligned across the sky. From top to bottom, this planetary lineup showcases Saturn, Jupiter and Venus. Clear Skies Everyone!
