Twin Conjunctions

click on graphic to see it larger   Monday February 18th the inner planet Venus will be about 1o from the outer planet Saturn as both rise a couple of hours before the Sun rises. The two will make for an interesting view with binoculars.

   Also, on Monday February 18th the 14-day old waxing gibbous Moon will be about 7-8o to the west from the star Regulus in the constellation Leo the Lion. The following day, February 19th, the full Moon will be about the same distance from Regulus but now on the east side. Both rise in the late afternoon about 2 hours before the Sun sets.

Taurus Gets ‘Moon Eye’

   Wednesday evening, February 13th the 9-day old waxing gibbous Moon will be within about 1o from the reddish star Aldebaran in the open star cluster the Pleiades. The v-shaped Pleiades make up the face of Taurus the Bull and the star is often referred to as the angry eye of the bull due to the star’s reddish color. The entire star cluster and the Moon all fit well within the field of view of binoculars.

    Further west is a planetary conjunction between Mars and Uranus. Both will fit well within the field of view of binoculars.

January Moon at Perigee

click on graphic to see it larger   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Monday January 21st. At that time the Moon will be at a distance of 28.015 Earth diameters 357,345 km (222,044 miles) from the Earth.

   The 16-day old Waning gibbous Moon rises shortly after sunset local time is visible all night. Over the southwestern horizon, as the Moon is rising,is the planet Mars which sets around midnight.

   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*

Moon – Uranus Conjunction

   Monday evening January 14th the 9-day old waxing gibbous Moon will be about 6-7o from the outer planet Uranus. Both are close enough to fit within a binocular field of view.
   However don’t realistically expect to see Uranus as Uranus has an apparent magnitude of 5.78 compared to the much brighter -12.0 apparent magnitude of the Moon.

January Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Wednesday January 9th. At that time the Moon will more or less be at a distance of 31.83 Earth diameters 406,116 km (252,349 mi.) from the Earth.

   Does our Moon actually go around the Earth? 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*

   On the day of the apogee the 4-day old waxing crescent Moon will be over the southwestern horizon at sunset local time.
