An Au is defined as the average orbital radius between the Earth and the Sun. It's a shorthand unit used to make Keplar's Laws calculations easier.
Since the distance between Earth and the Sun is equal to 1 AU, all the planets between Earth and the Sun orbit less than one AU away from earth.
In addition it is possible that Mars also orbits 1 AU away from Earth, but I am not certain as to weither or not it actually does.
What else can I help you with?
Which planets are less than one AU from the Sun?
Mercury and Venus are the only planets in our solar system that are less than one astronomical unit (AU) away from the Sun. Mercury is the closest planet to the Sun, with an average distance of about 0.39 AU, while Venus is next, with an average distance of about 0.72 AU.
Which planets have a year shorter than the Earth's year?
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.
How far apart are the planets?
The distance between planets varies greatly depending on their positions in their orbits. On average, the farthest planets (Neptune and Uranus) are around 19 AU apart, while inner planets like Earth and Venus are only a few AU away from each other. The closest distances occur during planetary alignments, where some planets can be less than one AU apart.
How far are the dwarf planets?
Of the current dwarf planets ("Current Members"). From the Sun Ceres = 2.77 AU Pluto = 39.48 AU Haumea = 43.34 AU Makemake = 45.79 AU Eris = 67.67 AU From Earth at the closest approach. Ceres = 1.77 AU Pluto = 38.48 AU Haumea = 42.34 AU Makemake = 44.79 AU Eris = 66.67 AU Where 1 AU = 150 million kilometres or 93 million miles (Approximately).
Are mercury and venus less than or greater than one AU from the Sun?
they are less than
Which planets are less than 1 au?
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.

What is smaller an astronomical unit or the average size of Neptune's orbit?
An astronomical unit (AU) is smaller than the average size of Neptune's orbit. 1 AU is the average distance between the Earth and the Sun, which is about 93 million miles. Neptune's average distance from the Sun is about 30 astronomical units, making it significantly larger than the distance of 1 AU.
Are Mercury and Venus less of greater than 1 AU from the sun?
They are less than 1 AU from the sun.
How many days does Eris spin once on axis?
All orbits are elliptical.Some orbits, like Earth's, are almost circular without much eccentricity in the orbit. The orbit of Eris is HIGHLY eccentric, with a perihelion of 38 AU and aphelion of 98 AU. The orbital period is 557 years.
How many planets are located 1 AU or less from the sun, and how did you determine this information?
There are four planets located 1 AU or less from the sun: Mercury, Venus, Earth, and Mars. This information is determined by measuring the average distance of each planet from the sun in astronomical units (AU), with 1 AU being the average distance from Earth to the sun.
Why are there so few planets with axes greater than 4 AU?
The majority of known exoplanets have orbits closer to their host star because these planets are easier to detect. Planets with axes greater than 4 AU are further away from their star, making them more challenging to detect using current observational techniques. Additionally, planets that are farther from their star may have longer orbital periods, meaning they require more time to complete a full orbit, further complicating their detection.
Is the orbit of Jupiter larger than the orbit of Earth?
Yes, Jupiter is about 5 times as far from the Sun.
How far apart are the planets?
The distance between planets varies greatly depending on their positions in their orbits. On average, the farthest planets (Neptune and Uranus) are around 19 AU apart, while inner planets like Earth and Venus are only a few AU away from each other.
