Wednesday evening, December 17th, the planet Mars sits low above the southwestern horizon at sunset. Mars is not particularly bright and it may be difficult to pick out amongst the stars in that part of the sky. However the three bright stars that make the asterism known as the Summer Triangle are over the western horizon forming a right triangle. Imagine a line extending east from the lower side of the triangle, from Vega to Altair, and you will point at Mars as this animated graphic shows.
