Moon Conjunction with Mars and Spica


   Tuesday morning November 14th the waning crescent Moon will be within a few degrees from the ‘Red Planet’ Mars and the bluish-white star Spica in Virgo the Harvest Maiden. Then as this animated graphic illustrates the waning crescent Moon will pass by Jupiter and then Venus over the next few days.

Venus – Jupiter Close Conjunction

   Monday Morning November 13th the inner planet Venus and one of the outer planets, Jupiter, will have a very close conjunction with Venus coming within less than one-half degree from Jupiter. Adding to the celestial scenery is the planet Mars and the 25-day old waning crescent Moon.

   Both should make for a striking view with binoculars or a low-power telescope eyepiece, or as a picture. Venus will be shining at a -3.9 apparent magnitude compared with Jupiter’s -1.7 apparent magnitude.
This graphic shows a view using a 25mm eyepiece on a 6″ Dobsonian Telescope.

Moon-Regulus Conjunction


   Saturday morning November 11th the 23-day old waning crescent Moon will be about 0.5o from Regulus, the ‘heart’ of Leo the Lion. Both will fit comfortably within the field of view of binoculars.

Changing Places!


   Over the next several days the inner planet Venus will be moving eastward past the outer planet Jupiter. They will be the closest on Monday November 13th when they will be separated by less than 0.5o. This animated graphic is set for 1-day intervals running from the 8th to the 16th and shows a simulated view using 10×50 binoculars at around 6:30 am CST.

Jupiter at Solar Conjunction


Thursday October 26th the planet Jupiter reaches conjunction with the sun, in effect behind the sun as we view the two from Earth. Jupiter will reappear later next month in the morning skies rising before the Sun rises.

October Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Wednesday October 25th. At that time the Moon will more or less be at a distance of 31.76 Earth diameters (404,154 km or 251,130 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*

   On the day of the apogee the 6-day old waxing crescent Moon will be over the southwestern horizon at sunset local time. Were it not so bright the glow of the Milky Way in the background might have been visible. Saturn is visible, but it is low above the horizon.
