 Titius-Bode Law
Johann Elert Bode was born on January 19, 1747 in Hamburg, Germany.
Together with Johann Heinrich Lambert, he founded the German language ephemeris, the Astronomisches Jahrbuch oder Ephemeriden [Astronomical Yearbook and Ephemeris] in 1774, later called simply Astronomisches Jahrbuch and then Berliner Astronomisches Jahrbuch, which he continued to publish until his death in 1826.
Johann Elert Bode died on November 23, 1826 in Berlin, Germany.

Titius was a Prussian astronomer whose formula showing the distances between the planets and the Sun was confirmed by Bode in 1772, when it was called Bode's Law (now the Titius-Bode Law).
Titius suggested that the mean distances of the planets from the Sun very nearly fit a simple relationship of A=4+(3x2n) giving the series 4, 7, 10, 16, 28, 52, 100, corresponding to the relative distance of the six known planets, up to Saturn, and a 'missing' value of 28 between Mars and Jupiter.

The German translation was undertaken by Johann Daniel Titius of Wittenberg.
Translators took a greater initiative than is now thought proper; Titius, probably because he was by nature self-effacing, not only left his additions unsigned but actually incorporated them in the text itself, with no hint that they were not the original work of the author.
He chose to make such an addition to the paragraph where Bonnet remarks that ``We know seventeen planets that enter into the composition of our solar system [that is, major planets and their satellites]; but we are not sure that there are no more'', going on to anticipate more discoveries as telescopes improve.

In 1766 Johann Daniel Titius of Germany noted that the then-known planets formed an orderly progression in distance from the Sun that could be expressed as a simple mathematical equation.
The astronomer Johann Elert Bode, also of Germany, published the law in 1772 in a popular introductory astronomy book, proposing that the missing 3 in the progression might indicate that a planet between Mars and Jupiter remained to be discovered.
Le Verrier also had difficulty convincing astronomers in his country that a telescopic search of the skies in the area he predicted for the new planet was not a waste of time.

 Extended Excerpt from Forward to "Ephemerides Of the Asteroids Ceres, Pallas, Juno, Vesta" written - by Eleanor Bach   (Site not responding. Last check: 2007-10-08)
As early as 1596 the young Johannes Kepler (1571~163O) published a paper in Tubingen entitled Misterium Cosmographicum which contained the significant sentence, “Inter Jovem et Martem interposui planetam.” Kepler had concluded that there must be a planet between Mars and Jupiter.
Titius noted the peculiar and regular proportion in the separation of the planets from each other and remarked upon the significant gap between Mars and Jupiter.
Johann Elert Bode (1747-1826), director of the Berlin Observatory, was a contemporary of Titius who was also concerned about the spacing of the planets.

 Dawn: Background
It is clear from the wording that Bode is following Titius, although he of course realized that the suggestion that the missing planet was a moon of Mars was preposterous, a fact he emphasized in the third edition of his book.
But he makes no acknowledgement to Titius; indeed, it is only in later editions that Bode identifies his source (possibly because Titius had pressed him to do so).
In the hands of Bode the relationship assumed a new importance, for Bode was a professional astronomer soon to take on international stature, and he was well-placed to act as apostle of the new law.

 BODE'S LAW AND THE DISCOVERY OF CERES
Towards the end of the century, the young Johannes Kepler, in one of the first publications that were irrevocably heliocentric, his Mysterium cosmographicum (1596), sought to make sense of the dimensions of the planetary system.
Titius, probably because he was by nature self-effacing, not only left his additions unsigned but actually incorporated them in the text itself, with no hint that they were not the original work of the author.
[19] How Titius could declare that Bonnet had drawn his ideas of unknown planets from Lambert is not clear, though perhaps Titius and Bonnet may have corresponded over the translation; but this reference of Titius to Wolff suggests that Wolff had indeed been Titius's original source.

 Johann Elert Bode History Summary   (Site not responding. Last check: 2007-10-08)
German mathematician and astronomer Johann Elert Bode was seemingly born to teach the world about the wonders of astronomy.
That accomplishment took place in 1766 by Prussian astronomer Johann Daniel Titius (1729-1796), who discovered a fascinating relationship among certain numbers, a relationship that seemed to have astronomical significance.
According to Titius, adding 4 to each of the numbers in the sequence 0, 3, 6, 12, 24,48, 96, 192, and so on, and then dividing each number by ten, would roughly derive the distances of the planets from the Sun (in astronomical units).

Johannes Kepler (1571-1630) thought there should be an additional planet between Mars and Jupiter.
A bit later Johann David Titius (1729-1794) noted the curious spacing of the planets-each was twice the distance from the Sun as its predecessor.
Johannes Bode formulated this as a "law" in 1778, leading to an intensive search for the "missing" planet.

 Bode's law --  Britannica Concise Encyclopedia - The online encyclopedia you can trust!
Once suspected to have some significance regarding the formation of the solar system, Bode's law is now generally regarded as a numerological curiosity with no known justification.
Of the first seven answers—0.4, 0.7, 1.0, 1.6, 2.8, 5.2, 10.0—six of them (2.8 being the exception) closely approximate the distances from the Sun, expressed in astronomical units (AU; the mean Sun-Earth distance), of the six planets known when Titius devised the rule: Mercury, Venus, Earth, Mars, Jupiter, and Saturn.
At about 2.8 AU from the Sun, between Mars and Jupiter, the asteroids were later discovered, beginning with Ceres in 1801.

Johannes Kepler (1571-1630) was convinced there was a mathematical plan underlying the structure of the system of planets orbiting the sun.
In 1724, philosopher Christian von Wolff (1679-1754) reproduced Gregory's series in a publication that was later read by physicist, Johann Daniel Titius (1729-1796).
Expressing the series this way drew renewed attention to the gap between the 4th and 5th terms, a gap that the numbers seemed to decree ought to be filled by something orbiting the sun at a distance proportional to 4 + 24 = 28.

In 1772 Daniel Titius published a number sequence that approximated the orbital radii of the six then-known planets.
Johann Bode, a German astronomer, was inspired to popularize it in his introductory astronomy book, and suggested that there ought to be a planet orbiting in the apparent gap at 2.8 AU (between Mars and Jupiter).
The first asteroid to be discovered (Ceres, in 1801) and more that came later effectively filled this gap.

Titius also reflected about the rule's prediction of a yet unknown planet orbiting between Mars and Jupiter.
The rule was subsequently plagiarized by Johann E. Bode, a young German astronomer, who, in his own book on astronomy, echoed the words of Titius.
The discovery of asteroids, beginning in 1801, which showed the average distance of the asteroid belt from the Sun fits the Titius sequence, helped guarantee the rule a place in history.
