On Monday December 7 the Moon is close to Mars, then on Tuesday December 8 the Moon is close to the bright star Regulus.
Saturn is visible low in the morning sky between the bright stars Regulus and Spica. On Thursday December 10 the crescent Moon is close to Saturn.

Mercury can be seen above the south-western horizon between half an hour to an hour after sunset. This week it moves in to the "Teapot" of Sagittarius, on on Thursday December 10 it is very close to the star Lambda Sagittarii, the "lid" of the teapot.
Jupiter is easily seen as the brightest object in the western evening sky. Jupiter is big enough to be appreciated in even the smallest telescope. If you don't have a telescope to view Jupiter, why not go to one of your local Astronomical Societies or Planetariums open nights? Jupiter's Moons are readily visible in binoculars or a small telescope.
