The Latest and Greatest on Pluto

NASA's $700 million New Horizons spacecraft will arrive in the Pluto system in mid-July after a nine-year 3 billion mile flight that started before Pluto was demoted to dwarf-planet status. 

But thanks to the Hubble Space Telescope, we already some fascinating stuff about Pluto and its five known moons. The Pluto system consists of four tiny satellites —Nix, Hydra, Kerberos and Styx — orbiting a "binary planet" comprised of Pluto and its largest moon Charon. They’re locked in odd rhythmic gyrations in a dance unlike anything in our solar system. 

What makes it so odd is that there's a double set of dances going on. First, Pluto and Charon are locked together in their own waltz "as if they are a dumbbell" with a rod connecting them. It's the solar system's only binary planet system, even though Pluto and Charon aren’t technically planets. 

But Pluto and Charon aren't alone, and that's where it gets more complicated. The four little moons circle the Pluto-Charon combo, wobbling a bit when they go closer to either Pluto or Charon, being pushed and pulled by the two bigger objects. 

Those four moons orbit Pluto-Charon in a precise rhythmic way, but with a twist: They also interact when they near each other. So it seems like they all dance to one overarching beat but not quite in the same way, just doing their own thing. 

Nix and Hydra exhibit chaotic rather than synchronous rotation, meaning they don't always keep the same side facing Pluto-Charon — and that it's very tough to predict their rotational movement. (Nearly every other moon in the solar system, including Earth's, is a synchronous rotator.) 

If you lived on Nix, you would not know if the sun is coming up tomorrow; it is that extreme. You'd have days where the sun rises in the east and sets in the north. 

Thanks for stopping by. I post here every first and third Thursday of the month. Don’t miss my June 17th blog as I’ll be posting on the James Webb Space Telescope.

My A to Z Road Trip Plan

If you read my May 27th post, you know I have a plan to visit 2-3 Road Trippers each day, and I'm doing it alphabetically. 

Wink. Wink. 



I doubt that I'll ever do anything again that doesn't involved organizing things from AtoZ.

So, I've visited A through G so far. Now I see that I have to adjust my plan, so if a keyword starts with the letter of the day, I'll visit that. I've already got my Z staked out. June will see a major slow down in my visits because I'm taking a vacation break, but I'll be back in July. Keep your engines running!

One thing Mario, my dashboard buddy/Muse, and I promised during this year's journey is a Road Side Rest Stop once in a while. This is where you can sit back, relax, breathe and rejuvenate. So here's our first Road Stop.







Unfortunately, there's often a very un-relaxing ad that pops up first, click it away and go for the relaxation. Even a few minutes puts you back on the road ready to roll.

Does planning help you save time and reach your goals? Are you good at planning and adjusting plans when you need to? What's been the best plan you've ever devised? Do you take a break to rejuvenate during the day?

Blog Blues and Brings Back Characters Who Blog

The first few months after the A to Z Challenge are always the hardest for me. I'm never sure what I'm supposed to do with myself. I sometimes find myself planning out posts that begin alphabetically, only to remember that A to Z is over. Sigh. What's a blogger to do? 

As a way to deal with my blog blues, I decided to come up with a few blogging challenges for myself, you know, to keep things interesting. On Mondays I'll focus on movies. Tuesdays are for reviews. On Wednesdays we wear pink . . . no wait, that's Mean Girls. 

Now as for my posts here on the Blogging from A to Z website, I'm thinking of bringing back my Characters Who Blog series (if you're new to this site, check out a few here and here). I had a lot of fun coming up with all the different literary and film characters and what they might write about if they had blogs of their own. 

Which prompts me to ask, what are some of your favorite characters from movies, TV and books? Are there any that stick out as particularly influential? Are they well known or tragically unheard of? And perhaps the bigger question, any Characters Who Blog requests? 

Happy Monday everyone, and as always, happy blogging!
