The solar system, showing the Sun and the planets in the order of their position from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto (which is now classified as a dwarf planet, but was considered a planet at the time the message was written).

The Earth is the third planet from the Sun - its graphic is shifted up to identify it as the planet from which the signal was sent.

In addition to showing position, the graphic provides a general, not-to-scale size reference of each planet and the Sun.
