The term planet
is ancient, with ties to history, science, mythology, and religion. The planets
were originally seen by many early cultures as divine, or as emissaries of deities.
As scientific knowledge advanced, human perception of the planets changed,
incorporating a number of disparate objects. In 2006, the International
Astronomical Union officially adopted a
resolution defining planets within the Solar System. Source
Space is the
boundless three-dimensional extent in which objects and events have relative
position and direction. Physical space is often
conceived in three linear dimensions, although modern physicists usually
consider it, with time, to be part of a boundless four-dimensional continuum
known as spacetime. In mathematics, "spaces" are examined with
different numbers of dimensions and with different underlying structures. Source
