Mercury and Venus trek across the northern part of Sagittarius as they barely make it into the evening sky.
\nThe moon goes farther north and south each month as it approaches a so-called major lunar standstill.
\nThe Geminid meteor shower peaks this week. The first astronomers who saw this shower described it as not very active, but things have changed.
