122P/de Vico
122P/de Vico (provisional designation: 1846 D1) is a periodic comet with an orbital period of 74 years. It fits the classical definition of a Halley-type comet with (20 years < < 200 years). It was discovered by in on February 20, 1846. During the 1846 apparition the comet reached a magnitude of 5 in mid March and was last observed in May. Its orbit was found to be elliptical and orbital calculations indicated that it would return between 1919 and 1925, however the comet wasn't detected. It was recovered on 17 September 1995 by the Japanese astr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comets
A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric ...
