Synopsis, one of:

\enspace


Insert a horizontal space of 1/2em, 1em, or 2em. The em is a length defined by a font designer, often thought of as being the width of a capital M. One advantage of describing space in ems is that it can be more portable across documents than an absolute measurement such as points (see Lengths/em).

This puts a suitable gap between two graphics.

See Spacing in math mode, for \quad and \qquad. These are lengths from centuries of typesetting and so may be a better choice in many circumstances than arbitrary lengths, such as you get with \hspace.
