Hendrik Van Gent
Hendrik van Gent (14 September 1899, Pernis – March 29, 1947, Amsterdam)''Album studiosorum Academiæ lugduno-batavæ MDCCCLXXV-MCMXXV'', A. W. Sijthoff, 1925, p. 376 was a Dutch astronomer. He moved to South Africa in 1928 in order to observe the southern sky at the Leiden Southern Station and the Union Observatory in Johannesburg. He obtained his PhD from Leiden University in 1931. He studied variable stars and also discovered three comets, namely C/1941 K1, C/1944 K2 and C/1943 W1. The Minor Planet Center credits him with the discovery of 39 numbered minor planets during 1929–1935. He died of a heart attack at the age of 47 while on leave in the Netherlands. The crater ''Van Gent Van Gent is a Dutch toponymic surname indicating an origin in the city Ghent, East Flanders. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Van Gent (crater)
Van Gent is a lunar impact crater on the far side of the Moon that is located to the south-southeast of the larger crater Konstantinov Konstantinov ( bg, Константинов, russian: Константинов) and Konstantinova (feminine; Константинова) is a common Slavic languages, Slavic surname that is derived from the baptismal name Konstantin and literally me .... About an equal distance to the east-southeast is Spencer Jones and to the southeast is Papaleksi. This crater joins the satellite crater Van Gent X to the northwest to form a double crater. Van Gent also partly overlies what appears to be an older crater remnant to the southeast. This in turn is joined to Van Gent N, which is joined to Van Gent P along its southeastern side. The result is a crater chain of sorts, consisting of five craters forming an arc with the concave side facing to the west. The rim of Van Gent is slightly distorted from a circle due to the craters with which it has formed. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
