Jupiter Orbit (Cosmic Octave)
183.58 Hz
Nearest note: F♯3, 13 cents below standard tuning
A tone calculated from a measured cycle, by doubling its frequency 36 times. It is calculated, not recorded.
How well is this supported?
Calculated from a measured value by a stated method. You can check the arithmetic. What the result means is a matter of interpretation.
The cycle is measured. The tone is calculated from it by doubling, so that it can be heard. Nothing in space makes this sound.
The button plays a plain tone. Start with the volume low. Phone and laptop speakers play low notes quietly; headphones or a speaker help.
Where this number comes from
Jupiter goes around the Sun in 4,332.59 days, about 11.86 years. 1 ÷ 374,335,776 seconds, doubled 36 times, is 183.58 Hz. That is an F♯, about 13 cents below standard tuning.
- Step 1. Start with the length of the cycle
Jupiter orbit around the Sun: 4,332.59 days.
- Step 2. Turn it into a frequency
One divided by that many seconds is 2.67 × 10⁻⁹ Hz. That is far too slow to hear.
- Step 3. Double it 36 times
Doubling a frequency raises it by one octave: the same note, higher. After 36 doublings it is 183.58 Hz.
- Step 4. Name the note
183.58 Hz is an F♯, 13 cents below standard tuning. A cent is one hundredth of the step between two neighboring piano keys. To play in tune with this tone, an instrument sets its A to 436.62 Hz instead of 440.
- Step 5. Keep doubling and the number lands in the range of light
41 more doublings give the frequency of light with a wavelength of 743 nm, which is red. This is arithmetic. It pairs a tone with a color; it does not show that the two are connected.
The method is Hans Cousto’s. Planet gongs explained walks through it and says what it does and does not show.

The same note in every octave
Each step doubles or halves the frequency. Tap one to hear it.
Entries close in pitch
Within 35 cents of this tone, in any octave. A cent is one hundredth of the step between two neighboring piano keys. Being close in pitch does not mean two things are connected.
