Comet 2020 F3 (NEOWISE) and Venus-Hyades Transit – Follow up

General location of the comet

   Here are pictures of the inner planet Venus in transit across the Hyades open star cluster, and of Comet 2020 F3 (NEOWISE) as both appeared over the northeastern to eastern horizon.
   Pictures were taken around 5:00 am CDT with a Canon Rebel EOS T7i DSLR using a variety of settings for exposure, shutter speed and so on. Location was near a baseball field at Legacy Park in Lee’s Summit, MO.

Venus, the Bull, and a Comet (yes!)

   The next several days offer some exciting opportunities for viewing: a few of the visible planets; the waning phases of our Moon and a few conjunctions with stars and planets; Venus crossing the stars of the Hyades open star cluster; and Comet 2020 F3 (NEOWISE).
   Comet 2020 F3 (NEOWISE) is one of the many comets discovered by the NASA NEOWISE mission.
   NEOWISE is a space-based telescope used to find and track ‘Near Earth Objects’, comets and asteroids, that may pose a threat to our planet.

Crescent Moon – Venus Close Conjunction

   Friday morning June 19th about an hour before sunrise look toward the eastern horizon for the 27.5-day old waning crescent Moon and the inner planet Venus. The two will be separated by about 1-2o and both will easily fit within the field of view of binoculars making for a striking view.
   You will be looking at a Moon that is about 24-hours from new Moon phase, and shines with an apparent magnitude of -8.90 compared with Venus shining with a -4.29 apparent magnitude.
   Off to the west over the eastern-southern horizon are the outer planets, Uranus, Neptune, Mars, and Dwarf Planet Ceres. Further to the west are the planets Jupiter and Saturn.

Venus at Inferior Conjunction – 2020

   Wednesday June 3rd the inner planet Venus reaches its orbital position known as inferior conjunction.
   This is one of four points along an inner planet orbit. At inferior conjunction Venus is between the Earth and the Sun – sort of like our new Moon phase – but not necessarily directly in line. If that were so, inferior conjunction at the same time as Venus in direct line with the Earth and Sun (a node crossing at inferior conjunction) it would be a somewhat rare transit of the Sun by Venus. These happen as a pair of transits about one time each century with the last pair of Venus transits in June 2004 and June 2012. Here are some pictures of the June 2012 Venus Transit. Here is a link to the Vimeo web site to watch a video of the 2012 Venus Transit.
   By the way the next pair of Venus Transits are December 2117, and December 2125.


    At this inferior conjunction Venus is 0.19o north of the ecliptic.

Moon – Spica Conjunction

   Tuesday evening the 10.5-day old waxing gibbous Moon will be about 5-6o from the blue-white star Spica in the constellation Virgo the Harvest Maiden. Both will fit within the field of view of binoculars.

Moon on the Move

   Over the next several days the Moon, as it waxes toward first quarter, will be moving toward the east and as it does the Moon will pass by several of the brighter stars along the Moon’s orbital path. This will take the Moon near Pollux, one of the Gemini ‘Twins’, and then past Regulus, the ‘Heart’ of Leo the Lion. On the 27th you may be able to see the open star cluster, M-44, or also known as the Beehive Cluster.

Thin Waxing Crescent Moon Near Venus – Mercury

   Saturday evening May 23rd look toward the western horizon for the very thin young 1.3-day old waxing crescent Moon. The Moon will be about 3-4o from the inner planet Venus and about 5-6o from the other inner planet Mercury. All three will easily fit within the field of view of binoculars and given the range of apparent magnitudes should make for a great view and even a picture.

The Inner Planets Meet

   Thursday evening May 21st, shortly after sunset, the two inner planets Mercury (apparent magnitude 0.41) and Venus (apparent magnitude -4.16) will be about 1o from each other. Both planets will fit within the 7o field of view of 7×50 binoculars as the graphics below show. Both planets are in motion along their respective orbital paths with Mercury moving toward the east while Venus is moving toward the west.

Say it Ain’t So!


   According to the web site Physics-Astronomy on May 16th the crescent Moon will be in a conjunction with the inner planet Venus and an outer planet, Jupiter, in a formation looking like a smiley face.

   This type of conjunction has happened in the past including one in 2 B.C. that has been suggested to be the ‘Star of Bethlehem’. More recently this triple conjunction did happen in December 2008, according to the article.

   Looking down from above the solar system on May 16th showing the orbital positions of Venus, the Earth, and Jupiter. From this graphic it shows that from the Earth you would have to look toward different directions to see either planet.

   No this will not happen.
   Here are reasons why this article about the conjunction is “fake news”.

   Venus is visible in the evening skies at sunset over the western horizon and sets around 9-10 pm local time. (Rises: 7:23 am – Sets: 10:24 pm)
   Jupiter is visible in the morning skies over the southern horizon and sets during the afternoon local time. (Rises: 12:45 am – Sets: 10:47 am)
   The article does not indicate which crescent Moon. Is this a waxing crescent Moon in the evening or a waning crescent Moon in the morning?
   The Moon is in fact a 22.8-day old waning crescent Moon in the morning skies. However the Moon is closer to Neptune and Dwarf Planet Ceres than it is to either Venus or Jupiter.

Two More Go Retro!

   Retrograde motion is an apparent motion of any Sun-orbiting object as viewed from one object to another object further from the Sun than the one the viewing is made from. Since we are based on the Earth our views of the planets and other objects orbiting the Sun come from that perspective. As I posted the other day, outer planets. for example, orbit the Sun more slowly than the Earth. So there are times when, as the Earth passes an outer planet, the outer planet appears to slow down and then move backward, to the west. After a period of time the planet resumes its regular eastward, or prograde, motion.
   The retrograde motion of an outer planet is easy to understand and even visualize, however the two inner planets also undergo retrograde motion. Half of each their respective orbit is eastward, prograde, but when they reach the opposite side of the Sun their orbit carries the inner planet around the Sun through inferior conjunction (between the Earth and Sun) toward the west, retrograde, for the other half of the orbit.
   For the record each ‘side’ of the orbit is known as an elongation. So at western elongation the inner planet is on the west side of the Sun and rises before the Sun rises – a morning planet. Half an orbit later the inner planet is at eastern elongation and rises and sets after the Sun – an evening planet.
   Venus is currently very prominent as an evening planet over the western horizon at sunset. The planet Mercury has recently passed through superior conjunction is gradually moving into the evening skies. Mercury is moving in prograde motion while Venus is moving in retrograde motion.
