In this work we present the software Astro3D. It is a simulator of motion of the celestial bodies in two references, the topocentric and the heliocentric. With Astro3D you can simultaneously observe the real movement and apparent movement of the Sun, the Moon and the planets of the solar system. It is a computational resource, developed for the teaching of physics and astronomy, which contributes to the visualization of motions with a very long time scale, in the understanding of abstract concepts and in the construction of mental models that can hardly be understood without this type of technological tool.
