Celestia is a real-time 3D astronomy software program that was created in 2001 by Chris Laurel. The program allows users to virtually travel through the universe and explore celestial objects that have been catalogued. Celestia also doubles as a planetarium, but the user is not restricted to the Earth's surface, like in other planetarium ...
0.854″ to 0.339″. Ceres(minor-planet designation: 1 Ceres) is a dwarf planetin the middle main asteroid beltbetween the orbits of Marsand Jupiter. It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazziat Palermo Astronomical Observatoryin Sicily, and announced as a new planet.
OpenUniverse is a 3D Solar System simulator created by Raúl Alonso Álvarez. It uses OpenGL 1.1 (implemented through Mesa 3D) to simulate the Solar system in complete 3D, including its planets and their major and minor moons, along with a few asteroids with real 3D models created from real data. OpenUniverse is free software distributed under ...
A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. Attempts to create such a model established the more general field of celestial mechanics. The results of this simulation can be compared with past measurements to check for accuracy ...
t. e. Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a man into Earth orbit and return him safely, ideally before the Soviet Union.
ʻOumuamua is a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft). [ 13] It has a red color, like objects in the outer Solar System.
Extraterrestrial sky. A historic extraterrestrial sky— Earthrise, the Earth viewed from the Moon. Taken by Apollo 8 astronaut William Anders while in lunar orbit, December 24, 1968. In astronomy, an extraterrestrial sky is a view of outer space from the surface of an astronomical body other than Earth .
A solar simulator (also artificial sun or sunlight simulator) is a device that provides illumination approximating natural sunlight. The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions.
