or minor planet,
small body orbiting the sun. More than 300,000 asteroids have been identified and cataloged; more than a million are believed to exist in the main belt between Mars and Jupiter, with many more in the Kuiper belt

, in astronomy, the fourth asteroid to be discovered. It was found in 1807 by H. Olbers. It is the third largest asteroid in size, with a diameter of c.326 mi (525 km). Its average distance from the sun is 2.36 astronomical units, and the period of its orbit is 1,325 days.

. In 1999 the space probe Deep Space 1 passed within 16 mi (26 km) of Braille's surface, the closest flyby ever of an asteroid. Braille measures only 1.3 mi (2.1 km) by 0.6 mi (1 km). Its orbit is highly elliptical; its periapsis, or closest point to the sun, being midway between earth and Mars, and its apoapsis, or furthest point from the sun, is more than three times further from the sun than the earth is. In addition, much of Braille's orbit is a considerable distance above or below the ecliptic, the plane in which the planets circle the sun. Because of its orbit and geologic composition, it has been suggested that Braille was torn from Vesta, which has a huge crater, as the result of Vesta's collision with another celestial body.

(human language)
/breyl/ (Often capitalised) A class of writing systems, intended for use by blind and low-vision users, which express glyphs as raised dots. Currently employed braille standards use eight dots per cell, where a cell is a glyph-space two dots across by four dots high; most glyphs use only the top six dots.

Braille was developed by Louis Braille (pronounced /looy bray/) in France in the 1820s. Braille systems for most languages can be fairly trivially converted to and from the usual script.

Braille has several totally coincidental parallels with digital computing: it is binary, it is based on groups of eight bits/dots and its development began in the 1820s, at the same time Charles Babbage proposed the Difference Engine.

Computers output Braille on braille displays and braille printers for hard copy.
