Humans have long studied the nights sky and discovered the worlds of Mercury, Venus,  Mars, Jupiter, Saturn, Uranus and Neptune. 


But beyond this realm of knowledge, another world shines brightly, just waiting to be discovered.


Planet 9 is not the first celestial body predicted by mathematicians before its visual verification, but pinpointing its precise location has taken a long time.


After 10 years of speculation we were finally able to send Gallivanter on its way to reveal Planet 9's secrets.


In its swift flyby our little probe sent back more data than we could ever have hoped for.

Lets take a look at its findings.


Introductory Information

Solar System | Frippery

Planet 9 is the ninth planet from the Sun.

At about 100 times the distance between our star and the Earth, or 100 astronomical units,  Planet 9 is the most distant planet in our Solar System.
This distance creates the longest orbit of the nine worlds, about 10.000 years, with the seasons lasting little over 2500 Earth years each.  
Theoretically, a human living on Planet 9 would experience only one seasons in his entire life, each season lasting for about 100 generations.

Orientation Planet 9 | Frippery

The planet is tilted at a near right angle, in which polar regions point toward and away

from the Sun, rather than upward and downward.

This tilt, thought to be the result of Planet 9's collision with at least one celestial body,

has also affected the orientation of Planet 9's 13 rings and 79 known moons.

Unlike the rings and moons of other worlds,  which orbit their home planets horizontally, 
those of Planet 9 orbit in a vertical orientation along the planet's tilted equator, much like a Ferris wheel.

Planet 9's Rings | Frippery

Drifting high above this windy ice giant is a quiet ecosystem of rings and satellites. 
Its rings are made from icy and rocky remnants from comets, asteroids, and moons.
The particles range in size from being as small as dust to big as mountains. 

How the rings are able to stay on track and intact has to do with Planet 9's smallest moons.
Called Sheperding moons, these tiny satellites orbit between the rings, 
and they seem to use their gravity to shape the ring material into circular paths.

Planet 9 is so inhospitable that even spacecraft aren't able to land. Because of Planet 9's inhospitable environment, the planet cannot support life - but some of its 76 known moons might. 

R-69-R, V-218-N, L-232-D, FED-2510-V, 
T-1011-K, E-111-VDB and SRQ-141-DV each have underground oceans that would make them potentially capable of sustaining life.

Probably the most iconic feature of Planet 9, is a bright purple storm that's been raging for over 300 years.
It's a giant, swirling collection of clouds with wind speeds of up to 1,300 miles per hour. 
This storm rages on Planet 9's north pole. Its over twice the size of Earth and shaped in a near-perfect hexagon.
Each of the six sides is believed to be the result of jet streams, which all encircle a massive hurricane.

While the clouds create a cool, calm veneer from afar, up close, they are whipped around by the most severe weather
in the Solar System.

Winds on the planet reach speed of over 1,200 miles per hour, nearly five times faster than the strongest winds recorded on Earth.
In fact, the winds are so powerful,
they break the sound barrier.

Pressure on Planet 9 | Frippery

62,86 km from Planet 9's Surface

Planet 9's atmosphere is so thick, that it creates a surface pressure similar to
what it would be about half a mile deep in the Earth's oceans.

Despite the planet's unhospitality, life may still exist in Planet 9's atmosphere.

About 30 miles up in Planet 9's  clouds, where the surface pressure and temperature are similar to those
on the surface on earth, scientists have observed strange dark streaks  that appear
to be absorbing ultraviolet radiation. A phenomenon that could be evidence of microbial life.

Planetary Composition

Solar Wind | Planet 9

Planet 9's hot iron core has had a surprising influence
on the planet's overall size, causing it to shrink. 
The hot iron core has slowly cooled and contracted over the planet's
4.5 billion years. In doing so, it pulled Planet 9's surface inward,
and has caused the planet to shrink 
radially by about 6,8 centimeters each year.


Despite its size, Planet 9 is actually the lightest planet. 
Because of its particular composition, Planet 9 is less dense than water. 
If the planet were placed on an enormous ocean, it would be able to float.


Today Planet 9 is dry, desolate and cold.
But billions of years ago, the planet was much warmer,

geologically active and had a watery surface.
Lake beds and river valleys snake along
the face of Planet 9, indicating that liquid water
was - for a time - present.

Gallivanter Probe | Frippery

It wasn't until recently that scientists began unraveling Planet 9's many mysteries.  

The Gallivanter expedition gave us many new insights, but new missions are in the works

with high hopes of revealing more of Planet 9's secrets.
