Eltanin

Moon and Saturn
The planet Saturn is near the Moon at dawn tomorrow. It looks like a bright star to the lower right of the Moon. A small telescope will reveal the largest of the planet’s almost 300 known moons.

More Venus and Jupiter
A conjunction between the two brightest points of light in the night sky, the planets Venus and Jupiter, plays out in the west the next couple of evenings. They are separated by less than two degrees, which is the width of your finger held at arm’s length.
Moon Phases
At the new Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated (position 1 in illustration). In other words, the Moon is between Earth and Sun. At first quarter, the half-lit Moon is highest in the sky at sunset, then sets about six hours later (3). At full Moon, the Moon is behind Earth in space with respect to the Sun. As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).
