APOD: Charon: Moon of Pluto (2015 Oct 02)

Post by APOD Robot » Fri Oct 02, 2015 4:06 am

Image Charon: Moon of Pluto

Explanation: A darkened and mysterious north polar region informally known as Mordor Macula caps this premier high-resolution portrait of Charon, Pluto's largest moon. Captured by New Horizons near its closest approach on July 14, the image data was transmitted to Earth on September 21. The combined blue, red, and infrared data is processed to enhance colors, following variations in surface properties with a resolution of about 2.9 kilometers (1.8 miles). In fact, Charon is 1,214 kilometers (754 miles) across, about 1/10th the size of planet Earth but a whopping 1/2 the diameter of Pluto itself. That makes it the largest satellite relative to its planet in the solar system. This remarkable image of Charon's Pluto-facing hemisphere shows a clearer view of an apparently moon-girdling belt of fractures and canyons that seems to separate smooth southern plains from varied northern terrain.

So Charon is a gray guy with a red hat.

Nice picture, but kind of boring. Why is there no Milky Way and a thunderstorm in the background? Okay, I get the 'no thunderstorm part', but why no Milky way? :shock:

Why so cynical? This is one of the most amazing, incredible pictures ever to appear on APOD!

It looks like the back of Darth Vader's head.

Was wondering what Earth would look like if it was barren.

It is nice to see that someone still considers Pluto a planet. Charon is the largest moon relative to its "planet". :)

Look at yourself in the bathroom mirror...the galactic center is the reflection of you in the mirror. Now imagine a great disk of material, about 10' in diameter, swirling around your reflections waist that extends as far again behind the physical you and is parallel to the floor. The reflection of you is the galactic center, the disk is the galactic plane and the physical you is the solar system. Now that you have located your home solar system, hold out your arm and lift it up about half way between your head and the ceiling look at a spot about an inch in diameter around your index finger, this is Pluto and the area in the image. Do you see any of the thin disk you imagined in that area?

It would look something like this.

A fascinating thing about the Earth is that it does have continents, and they would be visible even without the oceans.

Really – No rille on the upper half of Charon? What gives or didn't on top? At least they look like lunar rille.

Groovy. 8-)

Though the relief in that image is highly exaggerated.

Hasn't the time passed for taking APOD to task for the purty picture of 29 Sep?

Charon is another of those bodies that doesn't have enough gravity to do a good job of smoothing out impact damage. My first reaction to this photo was, "Sorry about the car, Dad."

The craters on Charon are much more clearly visible than on Pluto. Even on Charon, though, they appear to be considerably less numerous than the craters on our own Moon. Thanks, APOD, for this ongoing banquet of images from New Horizons ... keep them coming, I'm not too full yet.

Pluto a planet? I think the politicians should step in and give us a good legal definition. E.g. "Our solar system has 9 planets. These are the 9 objects in the system for which we have a planetary governor. The planetary governors meet each month in Las Vegas, NV and they each provide taxation/tribute to the Supremely Sovereign Systemic Liege, based on the population of their planets and a roll of the dice."

Yes, Charon is a bit of a car wreck of a moon. He is a battered old man, or cat. With a red hat.

Why is Charon's Northern cap RED?

Why do most of Charon's craters have a central peak?

I think something HIT the southern hemisphere...sunk much of it, caused Rilles..as things moved and then cooled. The Dark Material is some ejecti, from some type of geyser or something. Or something scraped through there...there is a depression there...almost like...No...couldn't be....MINED?????

Well...OK...some sort of EJECTI.....as it is powdered over some of the Rays of craters, like the one on the right side of the depression. If the crater was later, the material would be Lighter and on top of the Red? I think so. There is a partial looking crater on the left. The pattern looks like it goes left to right, and North....if an object hit a Mountain...at an ANGLE...then the spread of the debris might look similar? Momentum and direction?
There is also a GOUGE in the upper right, More Rilles on the far side?

Absolutely Fantastic Image and a Fascinating place....

Tis most unfortunate that we will have to wait another 124 years to be able to send another probe and image the other side of these worlds when the south polar region is in full sun
