The term planetarium is sometimes used generically to describe other devices which illustrate the Solar System, such as a computer simulation or an orrery. Planetarium software refers to a software application that renders a three-dimensional image of the sky onto a two-dimensional computer screen, or in a virtual reality headset for a 3D ...
The Eisinga Planetarium built by a wool carder named Eise Eisinga in his own living room, in the small city of Franeker in Friesland, is in fact an orrery. It was constructed between 1774 and 1781. The base of the model faces down from the ceiling of the room, with most of the mechanical works in the space above the ceiling.
An artist's concept of a planetary system. A planetary system is a set of gravitationally bound non-stellar bodies in or out of orbit around a star or star system.Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals [1] [2] and ...
Digistar is the first computer graphics-based planetarium projection and content system.It was designed by Evans & Sutherland and released in 1983. The technology originally focused on accurate and high quality display of stars, including for the first time showing stars from points of view other than Earth's surface, travelling through the stars, and accurately showing celestial bodies from ...
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer. Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky .
The Hayden Planetarium reopens at the American Museum of Natural History in New York, New York, United States, with a Silicon Graphics Onyx 2 and Trimension video system. 2001 The first mirror-projector combination is demonstrated at the Western Alliance of Planetariums conference in Eugene, Oregon, United States.
The planetarium includes a display for the current time and date. The plank that has the year numbers written on it has to be replaced every 22 years. The Eise Eisinga Planetarium is the oldest still working planetarium in the world. To create the gears for the model, 10,000 handmade nails were used. [10]
A planetarium projector, also known as a star projector, is a device used to project images of celestial objects onto the dome in a planetarium. Modern planetarium projectors were first designed and built by the Carl Zeiss Jena company in Germany between 1923 and 1925, and have since grown more complex.
