31 Days of Planets: Pluto

Day 10

Pluto is still a planet. I know everyone was so upset when Neil DeGrasse Tyson fought to "de-planetize" Pluto, but that's not what really happened. What really happened is that Pluto became special. Pluto became a dwarf planet - one of only two others (maybe). Of course, there are probably billions more dwarf planets, but Pluto gave us the deliberate ability to classify small planetary bodies as "not Earth-sized" and "not-gas giants." Instead of wandering around saying, "well, I guess we should call it a planet because it orbits the sun even though it's super small and different and doesn't really meet the criteria for a planet" we were able to definitively say: "Pluto is a dwarf planet."

It's like saying, "well, I guess we'll call you a hippie because you eat organic food and don't like war and ride bicycles, but your hair is too neat and your clothes are too carefully chosen," instead of "you are a hipster."

Pluto is in fact smaller than Eris and composed primarily of rock and ice. In fact, Pluto may host a hidden ocean. This means, if we run out of water because we humans are good at making bad decisions, we can mine Pluto. But then imagine the price of water! We'll be watching it like we watch the price of gas. 

"8.57 a gallon! Good heavens!" 
"Well that's what you get when you have to mine it from Pluto."

Pluto's atmosphere plays host to nitrogen, methane, and carbon monoxide. There may even be wind on the surface of Pluto.

In conclusion, just remember: Pluto is still a planet - just a dwarf planet.

Forecast calls for Moonquakes and Light Wishful Thinking

The problem with planetary science or astronomy is that the word "recent" doesn't mean anything to the average human being. Here's why.


1. First imagine one egg. (Not the yolkless kind.)


2. Now imagine 12 eggs.


3. Now imagine 12 million eggs.


I got lost imagining at about 12 eggs. The reason is because we group things. I substituted 12 eggs for a dozen. If you said to me, "Guess what! I have 50 trillion cells in my body!" I wouldn't imagine 50 trillion cells, I would imagine one body. So when I see an article titled "Moon's Scarred Crust Hints at Recent Activity", I get excited and then I get disappointed. Because the "recent" earthquake was 50 million years ago.


I thought for a moment that maybe, just maybe, the Moon was still barely warm enough to have tectonic activity. It's not. It's dead. But it did have earthquakes! 50 million years ago, that is.


The thing is, I want them to say "The moon had an Earthquake YESTERDAY!" Now that would be news. Not 27 pound lobster news. Not $4/gallon for gas  news or $5000 and a trip to Hawaii if you eat astronaut food for 4 months news or Google making Smartphone glasses news. But it would definitely EPIC SPACE NEWS.


Soon, I hope, there will be less of "we found a planet 100 million light years away! With water!" and more of "OMG Dinosaurs on Titan!"


For now, however, I guess I will just have to be satisfied with 50 million year old moon quakes.
