Jupiter and Saturn's 'great conjunction' will illuminate December sky
During the "great conjunction" on Dec. 21, Jupiter and Saturn will form a "double planet," appearing just a tenth of a degree apart -- or about the thickness of a dime at arm's length.

On the winter solstice, the gas giants will shine brightly as a "double planet." Jupiter and Saturn haven't been this close in the night sky since 1623! WABC By Alex Meier This month, Jupiter and Saturn are putting on an extraordinary show just in time for the holidays!

Over the next three weeks, the gas giants' paths will appear closer and closer together before an event that astronomers call "the great conjunction," according to NASA.

During the "great conjunction" on Dec. 21, the two will form a "double planet," appearing just a tenth of a degree apart -- or about the thickness of a dime at arm's length.

Skywatchers can differentiate Saturn and Jupiter from the stars because the planets will appear "brighter and more solid in the sky," NASA program officer and astronomer Henry Throop told "Good Morning America." He said the conjunction will be visible throughout the world, even in cities, on clear nights.

2020 is the start of a new decade, and with it comes several fascinating astronomy events!

In reality, the planets are still millions of miles apart, but every 20 years, the orbits of Earth, Jupiter, and Saturn periodically align, making these two outer planets appear close together. In 2020, however, astronomers are calling this phenomenon the "greatest" great conjunction, as the planets haven't been this close together and visible from earth since 1623.

Dec. 21 is also the winter solstice in the Northern Hemisphere, meaning it will be the shortest day of the year in terms of sunlight.

To spot Jupiter and Saturn's approach and ultimate conjunction, look for them low in the southwest in the hour after sunset, according to NASA.

I had a pretty good telescope back in Toronto, mounted on a tripod, and I could see the rings of Saturn and four moons circling Jupiter. It really is quite a thrill to see the actual planets for the first time, not in pictures or videos but the real things.

I setup a telescope and showed friends and family the planets years ago and actually could see the dark spots on Jupiter after it was struck by the fragments of the comet.  Lately, though, no one seems to have any interest in watching the sky even though I still do.

I've been watching this conjunction since Jupiter, and admittedly I thought Saturn was actually Mars at first, started showing up as the morning star with another planet nearby, it wasn't until later that Mars started showing up to the east that I realized it was Saturn that was near Jupiter.

I have both of your issues. I have to first find my telescope since I haven't taken it out since we moved. At least I know where all the optics are. I don't want to miss this, but remember, you can also see it with the naked eye.

BTW, this is a slow motion event, you'll have several nights to see the conjunction, as of right now they're close together, just on the 21st they will appear to be even closer then they will slowly separate for weeks and in a month the sun will be in the way.

I may send the drone up for pictures, but...only if the clouds clear.

Unfortunately the clouds never did clear off. Not sure the drone would have been a great choice anyway, the camera isn't that good.

You can go online and Google the Gemini meteor shower. There's a site which will bring up a sky chart showing where to look and at what times.

Tonight's the night, unfortunately for here, it looks to be an overcast day, there may be a chance of clearing by that short period of time to see this just after sunset for about an hour before they fall below the horizon.

Aww...I'm sorry. We will have clear skies and as I was brushing my teeth and listening to the news this morning, I realized I might have a decent view of it. Depends on how low on the horizon the conjunction will be

Dark now, actually the sun set here about 4:45, and it is a heavy wet snow falling right now, so will see them a little farther apart maybe in the next few days if it clears up.

I checked them out tonight. They looked like a single bright planet to the naked eye, but through binoculars they separated into two. I didn't have enough magnification to make out any moons or the rings of Saturn, though. 

If anyone's interested, here's where they were at approximately 6:15 PM Central, using the free astronomy software Stellarium.  Almost due southwest, near the horizon (the labels for Jupiter and Saturn are overlapping in the image):

And here's how close they appeared to each other when zoomed in on Stellarium (also showing moons):

Stellarium is pretty cool. It's basically what Starry Night used to be before they stopped selling their basic home version for $20 or so. Better still, it's free.

If you ever want to find out where something is, was, or will be in the sky (past, present, or future), then check it out.

Planets, stars, galaxies, nebulas, meteor showers, the constellations, etc. Even satellites and the ISS.
