The asteroid belt is a torus -shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets.
Signature. Ludwig van Beethoven[n 1] (baptised 17 December 1770 – 26 March 1827) was a German composer and pianist. He is one of the most revered figures in the history of Western music; his works rank among the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical ...

In 1800, hoping to resolve the issue created by the Titius-Bode Law, astronomer Baron Franz Xaver von Zach recruited 24 of his fellow astronomers into a club known as the “United Astronomical Society” (sometimes referred to the as “Stellar Police”). At the time, its ranks included famed astronomer William Herschel, who had discovered Uranus and its...
Despite common perceptions, the Asteroid Belt is mostly empty space, with the asteroids spread over a large volume of space. Nevertheless, hundreds of thousands of asteroids are currently known, and the total number ranges in the millions or more. Over 200 asteroids are known to be larger than 100 km in diameter, and a survey in the infrared wavele...
Much like the terrestrial planets, most asteroids are composed of silicate rock while a small portion contains metals such as iron and nickel. The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices and volatiles, which includes water ice. The Main Belt co...
Approximately one-third of the asteroids in the asteroid belt are members of an asteroid family. These are based on similarities in orbital elements – such as semi-major axis, eccentricity, orbital inclinations, and similar spectral features, all of which indicate a common origin. Most likely, this would have involved collisions between larger obje...
Originally, the Asteroid Belt was thought to be the remnants of a much larger planet that occupied the region between the orbits of Mars and Jupiter. This theory was originally suggested by Heinrich Olbders to William Herschel as a possible explanation for the existence of Ceres and Pallas. However, this hypothesis has since fallen out of favor for...
The asteroid belt is so thinly populated that several unmanned spacecraft have been able to move through it; either as part of a long-range mission to the outer Solar System, or (in recent years) as a mission to study larger Asteroid Belt objects. In fact, due to the low density of materials within the Belt, the odds of a probe running into an aste...
Jan 29, 2014 · The structure of the main belt is divided by unstable regions, seen most prominently at 2.5 au and 2.8 au (locations where an asteroid’s orbit is ‘in resonance’ with Jupiter’s orbit), that separate...

Apr 22, 2024 · Ludwig van Beethoven (baptized 17 December 1770 in Bonn – 26 March 1827 in Vienna; pronounced LUD-vig vahn BAY-TOH-ven) was a German composer. He wrote classical music for the piano, orchestras and different groups of instruments.
1815 Beethoven, provisional designation 1932 CE 1, is a carbonaceous background asteroid from the outer regions of the asteroid belt, approximately 30 kilometers (19 miles) in diameter. It was discovered on 27 January 1932, by German astronomer Karl Reinmuth at the Heidelberg Observatory.
