Once in a while the planets are arranged such that they are spread across the sky. The planets are not lined up in a straight line outward from the Sun but rather are arranged along the ecliptic. The ecliptic is the Earth’s orbital path around the Sun and the respective orbit of each planet is inclined from the ecliptic. And this is one of those times when it is easier to visualize the ecliptic. (see graphics below) Click here to read a previous posting about the ecliptic and planet inclination.
As the animated graphic is showing the terrestrial planets are not arranged in a straight line. This graphic shows the solar system out to Neptune and from this perspective the planets are obviously not in a straight line.
