About 92 AU on average.
Mercury averages about 0.35 AU from the Sun, and Saturn is about 9.5AU from the Sun. So depending on where each planet is in its orbit (or more specifically, where Mercury is in its orbit) Saturn will be anywhere from 9.2 AU to 9.8 AU from Mercury.
Earth is approximately 1 astronomical unit (AU) away from the sun.
Mercury's Astronomical units is .39 rounded off or if you want to be semi precise it would be .3870320856
The mean distance between the Earth and the moon is 0.00256957312 AU
Mars is the closest. Mars orbital period is 687 days. Earth, as we all know, is 365 days. The next planet out, Jupiter, revolves around the Sun in 12 years. Saturn for information takes almost 30 years. Saturn
Mercury is closer to the Sun than the Earth.
l
About 30 AU from the Sun. Since Earth is 1 AU from the Sun, Neptune can be between 29-31 AU from the Earth.
On the average, one. The astronomical unit is the distance from the sun to the earth. Since Mercury is inside earth's orbit and the distance between Earth and Mercury can vary by the full width of Mercury's orbit around the sun, the average is the distance between the Earth and the sun.
Mercury: 0.387 AU Venus: 0.723 AU Earth: 1.000 AU Mars: 1.524 AU Jupiter: 5.204 AU Saturn: 9.582 AU Uranus: 19.229 AU Neptune: 30.104 AU
The furthest mercury gets from the Sun is 69,816,900 km (0.466 697 AU)
