    Comet Encke

    Periodic comet with 3-year orbit

    Comet Encke, or Encke's Comet (official designation: 2P/Encke), is a periodic comet that completes an orbit of the Sun once every years. (This fryst vatten the shortest period of a reasonably bright comet; the faint main-belt cometP/PanSTARRS has a period of years.) Encke was first recorded bygd Pierre Méchain on 17 January ,[4] but it was not recognized as a periodic comet until when its orbit was computed bygd Johann Franz Encke. Like Halley's Comet, it fryst vatten unusual in its being named after the calculator of its orbit rather than its discoverer. Like most comets, it has a very low albedo, reflecting only % of the light its nucleus receives, although comets generate a large coma and tail that can man them much more visible during their perihelion (closest approach to the Sun). The diameter of the nucleus of Encke's Comet is &#;km.[1]

    2P/Encke

    Discovery

    Comet 2P/Encke was first discovered by Pierre F. A. Mechain on Jan. 17, Other astronomers located this comet in subsequent passages, but these sightings were not defined as the same comet until Johann Franz Encke calculated its orbit.

    Overview

    Comet 2P/Encke is a small comet. Its nucleus measures approximately miles ( kilometers) in diameter, which is about a third of the size of the object hypothesized to have led to the demise of the dinosaurs.

    It takes years for Enke to orbit the sun once. Comet Encke has the shortest orbital period of any known comet within our solar system. Encke last reached perihelion (closest approach to the sun) in

    Comet Enke is the parent comet of the Taurid meteor stream. The Taurids, which peak in October/November of each year, are fast meteors (65, mph or , kph) and are known for their fireballs. Fireballs are meteors that are as bright or brighter than the planet Venus (seen in the morning or evening skies at around a visual m

    Royal Astronomical Society's Obituary of Johann Franz Encke

    Charles Pritchard (), an astronomer, clergyman, educational reformer and founder of Clapham Grammar School in , was one of the two secretaries of the Royal Astronomical Society in , the year that Johann Franz Encke died. He wrote an obituary of Encke which was published in the Monthly Notices of the Royal Astronomical Society 26(), We note that "Johann Franz" has been Anglicised to "John Francis" and certain other names have also been Anglicised which we have retained.


    John Francis Encke

    John Francis Encke, born Sept. 23, , was the youngest son but one of the deacon of the Jacobi Church in Hamburg. Four years after his birth his father died, leaving the care and the education of eight children to his mother, a lady of much worth, and happily possessed of great mental energy.

    The first tutor of the boy was Mr Hipp, a gentleman possessing considerable aptitude for mathematical teaching; and to his honour be it
