Ecliptic

The Sun's path against the background of stars. It is defined by the plane of Earth's orbit around the Sun. It crosses the 12 constellations of the zodiac plus Ophiuchus, the serpent bearer. The other major planets of the solar system stay close to the ecliptic as they circle through the starry background, as does the Moon.
