Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Norton's Star Atlas
{{refimprove, date=August 2015 ''Norton's Star Atlas'' is a set of 16 celestial charts, first published in 1910 and currently in its 20th edition under the editorship of Ian Ridpath. The ''Star Atlas'' covers the entire northern and southern sky, with accompanying reference information for amateur astronomers. The charts used in the first 17 editions of the ''Atlas'' were drawn by a British schoolmaster, Arthur Philip Norton (1876–1955), after whom the ''Atlas'' was named. Norton intended his star atlas to be used in conjunction with the highly popular observing handbooks written by the British astronomers William Henry Smyth and Thomas William Webb, and consequently most of the objects featured in those guidebooks were marked on the charts. The ''Atlas'' also found favour among professional astronomers, earning it the reputation of the most widely used and best-known celestial atlas of its day. Arrangement and projection ''Norton’s Star Atlas'' became highly popular because of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anděl (crater)
Anděl is a lunar impact crater that lies in the rugged central highlands of the Moon. It was named after the Czech astronomer Karel Anděl. Nearby craters of note include Abulfeda to the south-southeast and Descartes to the east-southeast. About 85 kilometres to the east-northeast of the outer rim is the landing site of the Apollo 16 mission. The eroded outer rim of Anděl has been worn and distorted into a polygon In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed ''polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two to ...al shape, and is nearly non-existent to the south where Anděl G intersects the perimeter. The interior floor is nearly flat, with some irregularities to the southeast. There is a tiny craterlet located just to the southeast of the midpoint, but no central peak of any significance.

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
