By referencing this baseline, the relative distances of planets become a sequence of orbital radii, with Mercury residing at about 0. When we look up at the night sky, the planets appear as points of light, but their actual spatial relationships are defined by vast and dynamic scales that challenge human intuition.

4 AU and Neptune stretching to nearly 30 AU from the Sun. The sequence moves from the scorched proximity of Mercury, to the veiled clouds of Venus, our own blue marble, and the rusted plains of Mars.
Defining Astronomical Units The foundation for measuring cosmic gaps lies in the astronomical unit, or AU, a standard ruler calibrated to the average distance between Earth and the Sun, approximately 93 million miles or 150 million kilometers. This constant change means that a mission launched to Mars must carefully time its launch window to exploit the optimal relative distance.
