Orbits of extreme trans-Neptunian objects

Orbits of extreme trans-Neptunian objects

Are objects in the Kuiper Belt
Clustering in truth?
Or is that simply how they seem
Because of how we sleuth?

Bias observational
May lead
analyses astray,
Create this Planet 9 that we
Hypothesize today.

If it’s there,
It’s far away,
And very hard to see,
And yet the theory’s testable
As theories
all must be.

Kate Rauner

There’s an intense international search underway. If Planet 9 is out there, far from the Sun, “it is the solar system’s missing link of planet formation. Over the last decade, surveys of extrasolar planets have revealed that similar-sized planets are very common around other sun-like stars. Planet 9 is going to be the closest thing we will find to a window into the properties of a typical planet of our galaxy.” phys.org Not that we’ll get a probe there anytime soon.

I’m rhyming about Planet 9 in outer space, Not Plan 9 From Outer Space!


Planet X in the Far-flung Outer Solar System #poem #poetry #astronomy #solarsystem #planet

Man From PLanet X movie poster

This is the best I can do, since there is no image of Planet X yet

Watching perturbations.
In planets far away,
In cold realms way-past Jupiter,
Past Saturn, wobbles sway.

When Lowell discovered Pluto,
A store of luck was spent.
The famous dwarf is just too small
To tug

But orbital mechanics
Cannot be denied.
Something’s out there, far away.
Perhaps a Planet Nine.

Dwarf planets with companions
Among the plutoids hide.
The more we find, the better guess
Where Planet X resides.

Kate Rauner

Thanks to space.com for their article on Goblin (2015 TG387), another Pluto-sort of object tripped over in a long-term, ongoing sky survey that may ultimately find Planet X.

And we expect
Someone will spot
This Planet X.

The more plutoids
That we find,
The more our theories
Are refined.

#Pluto – Ringleader of the #KuiperBelt

Pluto's heart shaped feature - NASA

Pluto’s heart shaped feature – NASA

Pluto and Charon – a double system that steals that uniqueness from Earth/Moon. Pluto – orbiting in an ecliptic plane all its own, weird compared to the Sun’s planets. Pluto – largest of the Kuiper Belt objects (that status retrieved from Eris thanks to New Horizons). Pluto – in its own vast ring of millions of objects, the largest known object in the solar system beyond Neptune. Pluto – whose minions have infiltrated closer to the Sun as Neptune’s moon Triton and Saturn‘s Phoebe.

Pluto – no dull, frozen lump. “NASA scientists giddily throwing around words like ‘amazing’ and ‘mind-blowing.’ The pictures appear to upend some of our previous ideas about the presumed dead, dwarf planet. Most notably, it might not be dead.” [cbc.ca]

It’s “geology is ‘astoundingly amazing,’ declaimed Jeffrey Moore, New Horizons co-investigator. He focused on the ‘vast crater-less planes’ he’s also calling ‘not-easy-to-explain terrain’ and ‘icy frozen plains’.” blog.seattlepi.com

Pluto sports “one of the youngest surfaces we’ve ever seen in the solar system.” Some ice peaks are as tall as mountains in the Rockies, and still rising from geological activity not understood. All this, and scientists have only received about 2% of the data New Horizons has collected.

Pluto – who needs to be called a “planet” by bureaucrats on some distant, inner sphere?

BTW 1 – I was also thrilled to discover, once again, that what I know ain’t so. I’ve had in my head that the Sun would appear as merely another bright star from Pluto. No so! “The Sun from Pluto is still pretty dang intense. It would hardly look like just any other star: it would greatly outshine everything else in the sky. Painful to look at, most likely.” badastronomy

BTW 2 – I don’t get personally agitated over calling Pluto a dwarf-planet. Human beings love words to the point of arguing over the abstraction rather than seeing the reality. Are viruses alive? Can an Australopithecus anamensis mother birth an Australopithecus afarensis baby? Is Pluto a planet or a dwarf-planet? These are questions about labels, not about reality.

I’ve quoted a few articles above, but search on “Pluto New Horizons” and you’ll find tons.
