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.
Stars and planets rotate in the first place because conservation of angular momentum turns random drifting of parts of the molecular cloud that they form from into rotating motion as they coalesce. Given this average rotation of the whole body, internal differential rotation is caused by convection in stars which is a movement of mass, due to ...
The versatility of the ship systems and the options for ship design can allow the players to use Starfire as a tactical module for many strategic spacegames or as the basis for player-designed campaign games. Priced at $3.95 each, the games are a real bargain; it would be difficult to find a better gaming investment." [3]
Star Voyager is an outer space shooter for the Nintendo Entertainment System. The gameplay is a first-person shooter from inside the cockpit of a spaceship. The player navigates "sub spaces" of a larger "world map." Gameplay takes place between different subspaces. This game was released in Japan as Cosmo Genesis (コスモジェネシス).
Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward , in prograde motion .
Ionized material captured by the magnetic field lines will rotate with the Sun as if it were a solid body. As material escapes from the Sun due to the solar wind, the highly ionized material will be captured by the field lines and rotate with the same angular velocity as the Sun, even though it is carried far away from the Sun's surface, until it eventually escapes.
Newton defined the force acting on a planet to be the product of its mass and the acceleration (see Newton's laws of motion). So: Every planet is attracted towards the Sun. The force acting on a planet is directly proportional to the mass of the planet and is inversely proportional to the square of its distance from the Sun.
