While driving back home from Baltimore last night, my son and I saw a rare triple conjunction of the planets Mercury, Venus, and Jupiter in the early night sky. Last night’s show was the most compact arrangement of the planets, but they will be visible together all this week. Mercury and Venus will be a bit higher above the horizon at sunset each night even as Jupiter sinks lower. The picture on the left show the three planets to scale. Venus is the brightest object in the sky other than the Sun or Moon. It’s the planet nearest to Earth and, being closer to the Sun, brightly illuminated. Jupiter is the farthest of the three, but it’s large reflecting area makes up for the distance. Tiny Mercury is closest to the Sun, but reflects the least light to us of the three.
