Very little is known about Beethoven’s childhood. He was baptized on December 17, 1770 and was probably born a few days before that. Beethoven's parents were Johann van Beethoven (1740 in Bonn – December 18, 1792) and Maria Magdalena Keverich (1744 in Ehrenbreitstein – July 17, 1787). Magdalena's father, Johann Heinrich Keverich, had been Chief at ...
Beethoven seems to have tried to forget these bad thoughts by working very hard. He composed a lot more music, including his Third Symphony, called the Eroica. Originally he gave it the title Bonaparte in honour of Napoleon whom he admired. But when Napoleon crowned himself emperor in 1804, Beethoven began to think that he was just a tyrant who wan...
In a letter dated June 29, 1801, Beethoven told a friend in Bonn about a terrible secret he had for some time. He knew that he was becoming deaf. For some time, he had spells of fever and stomach pains. A young man does not expect to become deaf, but now he was starting to admit it to himself. He was finding it hard to hear what people were saying....
By 1814, Beethoven had reached the height of his fame. The Viennese people thought of him as the greatest living composer, and he was often invited by royal people to their palaces. It was the year in which he played his famous Piano Trio Op. 97 The Archduke. That was the last time he played the piano in public. His deafness was making it impossibl...
Beethoven’s music is usually divided into three periods: Early, Middle and Late. Most composers who live a long time develop as they get older and change their way of composing. Of course, these changes in style are not sudden, but they are quite a good way of understanding the different periods of his composing life. His first period includes the ...

Location of the main belt This plot shows the location of the main belt with respect to the planets and the Sun as well as the orbital structure of asteroid inclinations and number density of objects (yellow represents the highest number density, blue the lowest). Figure from DeMeo and Carry (2014).
Jan 1, 2014 · The P asteroids peak at about 4 AU, and the D asteroids at 5.2 AU; they are probably richer in low-temperature materials such as carbon compounds, complex organics, clays, water, and volatiles and represent the transition between the rocky asteroids of the main belt and the volatile-rich comets in the Kuiper Belt and the Oort Cloud.

Other articles where main-belt asteroid is discussed: asteroid: Distribution and Kirkwood gaps: …AU, a region called the main belt. The mean distances are not uniformly distributed but exhibit population depletions, or “gaps.” Those so-called Kirkwood gaps are due to mean-motion resonances with Jupiter’s orbital period. An asteroid with a mean distance from the Sun of 2.50 AU, for ...
The asteroid belt or main belt is a ring of small and large rocks and dust between the orbits of Mars and Jupiter. The biggest object in the asteroid belt is Ceres, a dwarf planet. The Kirkwood gaps separate the asteroid belt into several groups.
Jan 18, 2008 · The main belt region is shown in red, and contains 93.4% of all the objects. For reference, Mars orbits out to 1.666 AU, and Jupiter between 4.95 and 5.46 AU. The diagram was created by Piotr Deuar [1] using orbit data for 120437 numbered minor planets from the Minor Planet Center orbit database, dated 8 Feb 2006.
