The voice distance derives from the Latin “distantĭa”, present participle of the verb “distare” means “to be far”, “distar” and the prefix “dis” is said to be “divergence” and “distance”, the prefix “ia” “ indicates quality ”. The distance is the space or interval of time or place having a measure between two elements or events. The distance is the term used in various areas and subjects.
In mathematics, distance is a bilinear map that is the map defined in the Cartesian product of two vector spaces, which is the linear one in each of the two variables, which are two points on the line that joins them, exposed numerically. In more difficult spaces such as non-Euclidean geometry, which is the shortest path between two points, which is a straight portion with curvature named geodesic. In geometry, the geodesic line is determined as the line of minute length that joins two points in a given area and is contained in this extension.
But in physics, distance is a dimension that is manifested in units of length that is a standardized sum of length determined by meeting.
The distance in the area of astronomy consists of the separation between the different astral bodies. In the deepest part of the solar system it is manifested in kilometers or astronomical units with the symbol "ua".
This determination is carried out during the radar or laser procedure inside the solar system and by parallax and other indirect procedures outside of it.
