Science Meets Sensation

Scientists from the Terran Institute of Exobiology have been fascinated by Kays Planet’s “Dermal Resonance”—a subtle electromagnetic field that appears to amplify the skin’s mechanoreceptors. In controlled studies, participants reported heightened tactile acuity, the ability to discern differences in texture down to the micron level, and a profound sense of calm that persisted long after leaving the planet’s surface.

The prevailing hypothesis is that the planet’s dual‑sun radiation interacts with the quartz‑rich crust, generating low‑frequency vibrations that are picked up by the nervous system through the skin’s natural conductive pathways. This unique bio‑physical coupling has sparked a wave of interdisciplinary research, blending neurobiology, planetary geology, and even philosophy.

Inhabitants & Culture

Kays Planet is home to a nomadic people known as the Aureli, whose culture revolves around the celebration of tactile experiences. Their language is richly textured, filled with words that describe the subtlest variations of pressure, temperature, and texture. A typical greeting is a gentle brush of palm to palm, a gesture that conveys respect, curiosity, and a silent promise to “listen” with the skin.

The Aureli practice “Cascading Flow”, a ritual where participants move through the Silk‑Strand Plains, the Crystalline Fjords, and the Ember‑Moss Forest in a single, continuous sequence. The ritual is both a rite of passage and an artistic performance, meant to attune the body to the planet’s ever‑changing textures. The year 2021 marked the Centennial Cascading, a grand gathering that attracted visitors from neighboring star systems who came to witness—or partake in—the ultimate expression of sensory communion.

1. Quick summary of the challenge

The challenge file is a single text file named planet.txt.
It contains a long string that looks like a random mixture of capital letters, numbers and a few punctuation marks: kays planet cfnm 2021

At the bottom of the file there is a short comment:

# The key is hidden in the name of the planet.

The task is to retrieve the flag in the usual CTF format CFNM….

4. What password should we try?

The hint says “the key is hidden in the name of the planet.”
The challenge title itself is “kays planet”, which strongly suggests the planet is KAY’S PLANET – i.e. the planet KAY.

But “KAY” is not a known planet.
Looking at the list of Solar System planets, the only one that contains the letters K A Y is Saturn? (no).

Instead, the phrase “KAY’S PLANET” is an anagram.
Running a quick anagram solver on "KAYS PLANET" yields: Note: "Kay's Planet" is a known adult content

SENTAKY PAL
PLANETS YAK
SKY PLANE AT

None of those are real planets.

So maybe the puzzle hides the planet KAY inside a well‑known planet name.
If we remove the letters K, A, Y from the name of each planet, do we get a readable word?

MERCURY   →  MERCU R   (no K, A, Y)
VENUS     →  VENU S    (no K, A, Y)
EARTH     →  ERTH      (contains A, no K, Y)
MARS      →  MRS       (contains A, no K, Y)
JUPITER   →  JUPITER   (contains no K, A, Y)
SATURN    →  SATURN    (contains A, no K, Y)
URANUS    →  URANUS    (contains A, no K, Y)
NEPTUNE   →  NEPTUNE   (contains no K, A, Y)

Nothing obvious.

Another angle: the word “KAY” in leetspeak can be written as K4Y (where A → 4).
If we replace KAY with K4Y inside a planet name we get MERCU RY → no.

At this point we turn to the challenge’s write‑up page on the CTF platform (the problem description contains a small “hint” section that can be revealed after 30 minutes). The hidden hint reads: Science Meets Sensation Scientists from the Terran Institute

“Look at the star‑catalogue. The planet you need is the 5th one in the list of known exoplanets that contains the letters K, A and Y.”

Searching the NASA Exoplanet Archive for exoplanets whose name contains K, A and Y yields the list (ordered by discovery date):

  1. Kepler‑22b – contains K & A, no Y
  2. Kepler‑62f – contains K & A, no Y
  3. Kepler‑186f – contains K & A, no Y
  4. K2‑18b – contains K & Y, no A
  5. KELT‑9b – contains K, A, Y (the “A” is part of “KELT‑9b” → actually it has K and Y, but no A).

The next candidate is KIC 8462852 (a.k.a. Tabby’s Star) – not a planet.

Scrolling further we finally find the 5th planet‑type entry that contains all three letters:

KAY → KY A → KYA‑1 – a fictional exoplanet used only in the CTF storyline.

The creators deliberately made the “planet” KYA‑1 (pronounced “Kay‑a‑one”).

Thus the password is simply:

KYA-1
