Planets Meeting in the Night

 

If you go out into the Arkansas night early in the evening you’ll find the two brightest planets that are visible from Earth. 

The brightest of the two, low in the west, is the planet Venus.   Venus, over the coming weeks, will continue to move higher in the sky.  

At the top of the sky is Jupiter.   Jupiter is slowly falling behind the Earth in its’ more distant orbit.  This means that each night Jupiter is inching closer and closer to the setting Sun. 

In January the planets are seperated by a large margin (top image: click for closeup). However, with Jupiter inching toward the sunset, and Venus moving up and away, it will only be a matter of time before they pass each other.    That meeting will happen in the early evening hours of mid-March (bottom image).  Closest approach will occur on March 13th, on that evening Venus will be 3 degress north of Jupiter.  The night before, March 12th, Jupiter and Venus will be side by side in the evening sky – see image.   As a bonus, if you have a clear sky with a low western horizon, you may also be able to spot Mercury.

Over the next two months, when you are out in the evening, note the slowly shrinking distance between these two planets and you’ll be ready for the planetary meeting in the night.

Quadrantids Meteor Shower

The first good meteor shower of the year peaks Tues. night 3rd / Wed. morning 4th. The Quadrantids at thier peak can produce anywhere between 60 to 120 meteors or more per hour. Unlike their more famous summer cousins, the Quadrantids have a very sharp peak of only hours. This coupled with the cold weather of winter the Quadrantids is the least observed ‘major’ shower of the year. This year, the shower’s peak favors North America and Arkansas. The best time to observe this shower is in the early morning hours on Wed. morning. A waxing gibbous moon will light up the sky until 3am local time, washing out all but the brighter meteors. Thus, the best viewing will be between moonset and sunrise. Bundle up and let us know how many meteors you see. To learn more visit: Quadrantids Meteor Shower
