The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.
The tidally locked synchronous rotation of the Moon as it orbits the Earth results in it always keeping nearly the same face turned towards the planet. The side of the Moon that faces Earth is called the near side, and the opposite the far side. The far side is often inaccurately called the "dark side", but it is in fact illuminated as often as ...

Post-breakup the band has made two releases, The Nocturnus Demos, a collection of the band's pre-Earache recordings, and Farewell To Planet Earth, a DVD of live shows from various periods. In late 2008 Browning toured with his own band After Death under the Nocturnus name for two exclusive UK dates one at BUSK in Birmingham and the other in ...
Considering the Earth–Moon system as a binary planet, its centre of gravity is within Earth, about 4,671 km (2,902 miles) [25] or 73.3% of the Earth's radius from the centre of the Earth. This centre of gravity remains on the line between the centres of the Earth and Moon as the Earth completes its diurnal rotation.
As Caelus Nocturnus, he was the god of the night-time, starry sky. In a passage from Plautus , Nocturnus is regarded as the opposite of Sol , the Sun god. [ 24 ] Nocturnus appears in several inscriptions found in Dalmatia and Italy , in the company of other deities who are found also in the cosmological schema of Martianus Capella , based on ...
A classical planet is an astronomical object that is visible to the naked eye and moves across the sky and its backdrop of fixed stars (the common stars which seem still in contrast to the planets). Visible to humans on Earth there are seven classical planets (the seven luminaries ).
