If you're willing to rise early, you may spot a beautiful sight in the eastern sky on Tuesday, Oct. 10.
About three hours before sunrise, the bright planet Venus and a 17%-lit crescent moon will appear just 5 degrees from each other, and the pair will be easily visible to the naked eye. Venus will rise about half an hour after the moon. You can get the exact rise times for your location on timeanddate.com's Night Sky Map & Planets Visible Tonight page.
It will also be possible to see a couple of bright stars around the crescent moon and Venus. The moon will hang in front of the constellation Leo, the lion. It will be between the two brightest stars in Leo: Algieba and Regulus.
Sometimes called the Lion's Heart, Regulus is the 21st-brightest star in the sky. Located about 79 light-years from the solar system, it's part of the sickle of Leo, the head and front of the lion, which resembles a backward question mark.

There are six stars in the sickle, with Regulus at the bottom. The fourth star, visible on the other side of the crescent moon, will be Algieba, which is about 130 light-years from the solar system and one of the clearest double stars in the night sky, according to Astronomy Now. Viewing Algieba through a good small telescope will split it into a pair of golden stars.
The crescent moon will move away from Venus and the bright stars as it continues its orbit, but equally beautiful sights await.
On the mornings of Wednesday, Oct. 11 and Thursday, Oct. 12, it will be possible to glimpse the ever-slimmer crescent moon just 10% and 5% illuminated, respectively, as it approaches its new-moon phase, when it will eclipse the sun on Saturday, Oct. 14 as seen throughout the Americas.
