Fényi is a small lunar crater on the far side of the Moon

Far side of the Moon

The far side of the Moon is the lunar hemisphere that is permanently turned away, and is not visible from the surface of the Earth. The far hemisphere was first photographed by the Soviet Luna 3 probe in 1959, and was first directly observed by human eyes when the Apollo 8 mission orbited the Moon...

Mare Imbrium

Mare Imbrium, Latin for "Sea of Showers" or "Sea of Rains", is a vast lunar mare filling a basin on Earth's Moon and one of the larger craters in the Solar System. Mare Imbrium was created when lava flooded the giant crater formed when a very large object hit the Moon long ago...

An impact event is the collision of a large meteorite, asteroid, comet, or other celestial object with the Earth or another planet. Throughout recorded history, hundreds of minor impact events have been reported, with some occurrences causing deaths, injuries, property damage or other significant...

Mendel (lunar crater)

Mendel is a large Impact crater that lies on the far side of the Moon. It is located in the southern fringe of the huge skirt of ejecta that surrounds the Mare Orientale impact basin. To the south-southwest of Mendel is Lippmann, an even larger crater....

 shows a radial pattern of grooves and braids running from north to south. Only a ring of material protrudes upward from this bed of ejecta, displaying the location of the original rim. There is a small craterlet along the northeast inner wall.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Fényi.

Fényi	Latitude Latitude In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the Equator. The latitude is an angle, and is usually measured in degrees . The equator has a latitude of 0°, the North pole has a latitude of 90° north , and the South pole has a...
