Venus and Saturn will be in conjunction this weekend, appearing side by side in the night sky during January's post-sunset "planet parade."

Venus, Saturn, Jupiter and Mars will appear to line up and be bright enough to see with the naked eye in the first few hours after dark. This weekend, Venus and Saturn get especially cozy.

NASA and famed astronaut Buzz Aldrin say stargazers have the best chance of catching a glimpse of Saturn and Venus in alignment starting Saturday. The planets have been shuffling toward each other in the sky and will appear closest this weekend, appearing only inches apart to the human eye.
