The Astronomical Predictions of Andrew Jackson Davis
John DeSalvo, Ph.D.


Andrew Jackson Davis' first book "The Principles of Nature" was first published in 1847. He started receiving the information for the book in 1846 through 1847 (for 15 months), so it is important to know the dates that he first made statements about certain astronomical phenomena. As an amateur astronomer and also having taking classes in Astronomy when I was in college, I was astonished to read of his predictions. I decided to verify the dates he made certain statements and compare them with discoveries in astronomy to rate his accuracy. I must say that I have never came across any prophet, psychic, medium, etc. that comes close to the accuracy of Davis. Also, his predictions are specific and not vague like Nostradamus or other seers.

It is important to understand how he received his information. It was not like channeling, from spirits, or other intermediary's. He claims to be able to go into a higher sphere of consciousness, or dimension if you like, which is higher than our physical universe. This higher consciousness which he experiences allows him to see and experience directly higher laws and realities of the universe. Thus he directly experiences his revelations and sees the truths directly. Obviously, I can not explain exactly this experience, but from his description we know it is a higher level of consciousness, awareness, and understanding.


In March, 1846 Andrew Jackson Davis said that there are 9 planets in our solar system. At that time, astronomers knew only of 7 (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus). Neptune and Pluto were not discovered, although some scientists speculated that more planets would be found. Approximately 6 months later (September, 1846), Neptune was discovered. Pluto was not discovered until 1930, which was 84 years after Davis' prediction. What is also very significant and incredible is that Davis' correctly stated the density of Neptune before it was even discovered.

Davis also stated that Neptune had 6 moons or satellites around it. If you check an up to date astronomy reference book, it will state that Neptune has 8 moons. So, Davis appears to be wrong, but not too far off, considering he predicted the number of moons of Neptune before Neptune was even discovered. On looking more closely into this, I found out that Neptune actually has 6 SMALL MOONS orbiting close to the planet and 2 other moons at much greater distances. Was Davis just seeing the closer ones around the planet in the way he was observing Neptune? We can only speculate but this could possible explain his 6 moons instead of 8. It is important to note that Davis said clearly that he was not infallible. He made errors just like everyone else and grew spirituality each day.

Davis also mentioned that the atmosphere of this eighth planet (he obviously did not call it Neptune since it was not discovered and named yet), consisted of little oxygen, being mostly composed of fluorine and nitrogen. Up to the 1980's, astronomer's using spectroscopic analysis of the planets, did not find any nitrogen on Neptune. In 1989, Voyager 2 flyby of the planet discovered large frozen belts of nitrogen on the poles of one of the moons of Neptune (Triton). This showed that at least nitrogen was in the system of Neptune and maybe not yet discovered on the planet. Again, a very interesting recent discovery.

Davis also talked about the surface of Venus. Venus is a planet with a perpetual cloud cover so our telescopes and normal space probes can not see the surface. The Pioneer satellite, orbiting Venus, used radar to penetrate the cloud cover. It produced a Global radar map of its surface. The map revealed that Venus is less mountainous and rugged than Earth, with most of its surface being low, gently rolling planes. It is studded with very high mountains, the highest being 6.8 miles. Now this is AJD's description of the surface of Venus from Principles of Nature", p203. "there are very high mountains and ejected rocks, that disturb the otherwise smoothness of its appearance. Some of these are several miles higher than any upon the earth." That is a pretty close representation of the Global radar map of the surface of Venus from Pioneer.

Another interesting statement that AJD makes in his first book is that "our solar system revolves around another system. The wonderful sun or centre to which our solar system belongs, is but a remote planet of another system existing prior to its formation." This was confirmed later by a Russian astronomer, Maedler, who determined that our solar system is moving around a point in the direction of the Pleiades, requiring many millions of years to complete a single revolution.

To be fair, not all of his statements concerning our solar system are accurate. It is possible that we may revise our current knowledge in favor of his statements, but his high degree of accuracy is far greater than any other known seer, prophet, psychic, that I have ever heard of. Even Nostradamus was very vague in his prophecies, but AJD is very specific
