Angle
In space and astronautical engineering, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles are used to describe the orientation and position of spacecraft, satellites, and other objects in space. They are also used to calculate trajectories, determine the direction of thrust, and measure the distance between objects. In addition, angles are used to describe the shape and orientation of celestial bodies, such as planets, moons, and asteroids. The most commonly used unit of measurement for angles in space and astronautical engineering is the degree, although radians and other units may also be used.
