Which planet has the highest orbital inclination among the planets?
Quick Answer
Mercury has the highest orbital inclination of the planets relative to the Sun’s equatorial plane. Its orbit is tilted by about 7 degrees compared with the ecliptic reference frame.
The Full Story
Mercury’s orbit is the most inclined of the major planets, with an inclination of about 7 degrees relative to the ecliptic. That makes it the planet whose path is most tilted in comparison with Earth’s orbital plane. This inclination contributes to Mercury’s unusual orbital dynamics and helps make it a valuable subject in celestial mechanics. Though the tilt is modest by human standards, it is the largest among the planets.
