This evening will feature a a pretty set of planets and the Moon low in the sunset. Mercury, Mars, and a thin crescent Moon will be visible above the glow of the setting Sun.
The Moon will be a very thin sliver, a mere 4% illuminated. Look 7° above the Moon for Mars. Mercury will be harder to spot, about 7° below the Moon, closer to the sunset and a little north (to the right).
This evening will feature a 6 day old crescent Moon 7° from Mars. Look for a bright orange object a few degrees north (to the right) and a bit below the Moon to spot the planet. Mars should be bright and obvious at about +1 magnitude next to the Moon.
Over the coming weeks Venus and Mars will dance in the sunset. Close approach will occur on February 2nd, with the pair about 5° apart. They will remain in close proximity in the sky for much of February, finally disappearing into the glare of sunset around the end of the month.
On the evening of the 31st, a pretty crescent Moon will join this dance in the sunset, forming a triangle about 5° across. A 16% illuminated crescent moon with make a lovely trio with the bright planets.
This evening at sunset a nice crescent Moon and the bright planet Jupiter will be quite close. As sunset around 19:00 the two will be separated by a mere 46′, just a little over the width of the full Moon. The two should make a very attractive pair as they sit above the glow of sunset.
Keep an eye out for Mercury and Venus closer to the horizon. At 19:00 Venus will be 9° above the horizon with Mercury a bit higher at 14°. The Moon and Jupiter will be higher yet around 25°. Since Mars and Saturn are also visible in the southern sky all five naked eye planets will be visible.
