Moon and Saturn Conjunction


   Tuesday morning February 21st the 23.5-day old waning crescent Moon will be 4-5o away from the planet Saturn as this graphic shows. With 7×50 binoculars the two should make for a striking pair.

Moon Cruises Past Planets and Stars

feb5-bino
   Over the next several evenings the Moon, as it orbits toward the east and waxes from crescent to first quarter phase will pass by several planets, dwarf planets, and star clusters. On the evening of February 5th the Moon will be close to the reddish star Aldebaran, the ‘eye’ in the face of the angry bull, Taurus. This should make for a nice view with binoculars or low power eyepiece when the Moon will sort of overlay the stars of the open star cluster the Hyades.

   These two animated graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North. They show the sky at one day intervals starting with February 1st and ending with February 5th.

January Moon at 2nd Descending Node

(posting this ahead of time – on the road back to Quito and no Internet for a couple of days)

29jan-descending-node
   Sunday January 29th the 2-day old thin waxing crescent Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
   
   On the day of the node crossing the 2-day old waxing crescent Moon will be over the southwest horizon, below Mars and Venus, at sunset local time. The outer planet Neptune is there but too dim to be seen without some sort of optical assistance.
   These two graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North.

January Moon at Apogee

22jan-apogee_moon Our Moon reaches apogee, (greatest distance from Earth), on Sunday January 22nd. At that time the Moon will more or less be at a distance of 31.74 Earth diameters (404,914 km or 251,601 miles) from the Earth.
   Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Read this very informative article about the Earth-Moon system and their orbital motions, written by Joe Hanson. “Do We Orbit the Moon?”

   On the morning of the apogee Moon the 24-day old waning crescent Moon rises a couple of hours before the Sun and is visible over the southern horizon.

   Below is a picture of the Moon and Venus through the clouds this evening.
