If you have a dark sky, you'll also see the winter Milky Way rising between Orion and Gemini, bisecting the sky. The constellations Perseus and Cassiopeia are nearly overhead and are easy to see, even from the city. If you haven't tried to find the asteroids Ceres and Vesta yet, they're at their best this month, too. And they're easy to find near Jupiter. All three objects reach opposition in December, when they're best for viewing.
Mercury, Venus and Saturn line up in the predawn sky from the 9th through the 21st.
Finally, on December 25, watch Jupiter next to the moon an hour past sunset. To study the stars and planets, and to learn about all of NASA's missions, visit www.nasa.gov.
