au sommet, au top niveau
The term is au naturel, from the French, and literally means in the natural state. The definition is "with no elaborate treatment, dressing, or preparation." Salad can be au naturel. Hair can be au naturel. It does not necessarily have to refer to the human body, but it frequently does.

Mercury and Venus are always less than 1 AU from the sun. The Earth's orbit averages 1 AU from the sun, so sometimes the Earth is less than 1 AU, sometimes it is more.
0.387 is the average distance from the Sun to Mercury in AU. Note: AU=astronomical unit
All planets in the Solar System are less than 2 billion miles from the Sun, except for Neptune, which is 2.8 billion miles away.This answer does not consider Pluto, because it is no longer considered to be a regular planet.
Mercury and Venus both orbit the sun at less than 1 astronomical unit (AU). Mercury orbits the sun at an average distance of .387 AU (about 58 million km) and Venus orbits at an average distance of .723 AU (about 108 million km). Compare these distances to 1 AU which is about 150 million km, which happens to be the average sun to earth distance; which defines the astronomical unit.
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.
In our solar system, the planets Mercury and Venus orbit at a distance less than 1 AU. Since the Earth orbits at an "average" distance of one astronomical unit, you might also argue that Earth, owing to orbital eccentricity, sometimes is closer to the Sun than one AU.
Mars orbits beyond Earth, so it is more than 1 AU from the sun.
Mercury's Astronomical units is .39 rounded off or if you want to be semi precise it would be .3870320856
At its furthest (aphelion) 0.467 AU and at its nearest (perihelion) 0.307 AU.
Mercury is 0.387 AU from the Sun. Bonus fact: The average temperature on Mercury during the day is 662ºF! Here's a website where you can learn more about the planets
