1631 Kopff
1631 Kopff, provisional designation , is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 11 October 1936, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland. It was later named after German astronomer August Kopff. Classification and orbit ''Kopff'' is a member of the Flora family, one of the largest collisional families of stony S-type asteroid. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.21 and an inclination of 7 ° with respect to the ecliptic. First identified as at Heidelberg in 1926, the body's observation arc begins with its official discovery observation at Turku in 1936. Physical characteristics Rotation period In November 2003, a rotational lightcurve of ''Kopff'' was obtained from remote photometric observations at the Tenagra an ...

August Kopff
August Kopff (February 5, 1882 – April 25, 1960) was a German astronomer and discoverer of several comets and asteroids. Kopff studied and worked in Heidelberg, getting his PhD there in 1906 and he then joined the Humboldt University of Berlin where he became the Director of the Institute for Astronomical Calculation. He discovered some comets, including periodic comet 22P/Kopff and the non-periodic C/1906 E1. He discovered a number of asteroids, including notably the Trojan asteroids 617 Patroclus and 624 Hektor 624 Hektor is the largest Jupiter trojan and the namesake of the Hektor family, with a highly elongated shape equivalent in volume to a sphere of approximately 225 to 250 kilometers diameter. It was discovered on 10 February 1907, by astronomer .... The lunar crater '' Kopff'' is named after him, as is the asteroid 1631 Kopff. Minor planet 805 Hormuthia is named after his wife, Hormuth.

Kopff (crater)
Kopff is a lunar impact crater that lies along the eastern edge of the inner Mare Orientale impact basin, on the western limb of the Moon. In this position the crater is seen from on edge from the Earth, and its visibility is affected by libration. This situation makes it difficult to discern much detail about the crater unless it is viewed from orbit. At one time this crater was considered to have formed due to volcanic activity,''The moon as viewed by lunar orbiter'', 1970, NASA SP-200 by L. J. Kosofsky, Farouk El-Baz in contrast to most lunar craters which are considered to have been created through impacts. However it is more likely that the crater was formed by an impact against a surface that was still partly molten. This has left the crater with a sharp-edged, circular rim and a flat, dark-hued interior floor. Indeed, the albedo of the interior floor matches that of the lunar mare to the west. The southeast part of the floor is fractured with a series of narrow rilles. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
