This genre of computer and video game simulates trading and combat in outer space; as exemplified by Elite. They are often arcade-like in mechanics, as opposed to pure space flight simulators . Subcategories
The common noun ‘moon’ (not capitalized) is used to mean any natural satellite of the other planets. Tidal force is the combination of out-of-balance forces and accelerations of (mostly) solid bodies that raises tides in bodies of liquid (oceans), atmospheres, and strains planets' and satellites' crusts.
All eight planets in the Solar System orbit the Sun in the direction of the Sun's rotation, which is counterclockwise when viewed from above the Sun's north pole. Six of the planets also rotate about their axis in this same direction. The exceptions – the planets with retrograde rotation – are Venus and Uranus.
The modern space flight game genre emerged at the point when home computers became sufficiently powerful to draw basic wireframe graphics in real-time. [1] The game Elite is widely considered to be the breakthrough game of the genre, [1] [2] [3] and as having successfully melded the "space trading" and flight sim genres. [4]
Another common form of resonance in the Solar System is spin–orbit resonance, where the rotation period (the time it takes the planet or moon to rotate once about its axis) has a simple numerical relationship with its orbital period. An example is the Moon, which is in a 1:1 spin–orbit resonance that keeps its far side away from
The red planet is stationary; the force F(r) is balanced by a repulsive inverse-cube force. A GIF version of this animation is found here. Figure 2: The radius r of the green and blue planets are the same, but their angular speed differs by a factor k. Examples of such orbits are shown in Figures 1 and 3–5.
That has upset some current, part-time Air National Guard members involved in space missions because the proposed move would force them into the full-time, active-duty Space Force. Show comments ...
Since the launch of space-based telescopes such as Kepler space telescope, it has been made possible to determine and estimate the obliquity of an extrasolar planet. The rotational flattening of the planet and the entourage of moons and/or rings, which are traceable with high-precision photometry provide access to planetary obliquity, ψ p .
