About 206,000 given that 1 parsec is 3.06 x 1013 km and 1 AU is 149.6 x 106 km __________________ 1 Astronomical Unit (AU) is the average distance from the Sun to the Earth, about 150 million kilometers or 93 million miles (approximately). We use AU when we talk about distances between objects WITHIN the solar system. One "parsec", or "parallax-second of arc", is the distance that an object would be (from Earth) if we measure a one second of arc difference in the relative direction of a "nearby" object, measured from one side of the Earth's orbit to the other. That gives us a baseline distance of 2 AU, about 300 million km or 186 million miles. You can calculate the distance of one parsec using trigonometry; the base of the triangle is 2AU, and the opposite angle is 1 second of arc (1/3600th of a degree). Roughly, one parsec is about 3.26 light years. We use parsecs to measure distance between stars, or between objects in the galaxy.
. . they are a convenient unit. Another convenient unit is the parsec.
Planet Earth.One astronomical unit is roughly the distance between planet Earth and the Sun.
AU is short for astronomical unit. 1 AU is about 93 million miles, which is the distance between Earth and the sun.

kilometer, AU (astronomical unit), light year, parsec.
-- the Astronomical Unit -- the Light Year -- the Parsec -- the Magnitude
The "Astronomical Unit" is approximately the radius of Earth's orbit from the Sun. It's about 93,000,000 miles.
Three units are commonly used in astronomy - the astronomical unit; the light-year; and the parsec.
The astronomical unit called a parsec is based on the idea of parallax.
Since you've not provided any clues... It could be - ight year, parsec or astronomical unit
The usual units of measure are; Astronomical Unit (AU) Light year Parsec
A kilometre can be consider as approx (1/30.86) trillionths of a parsec, a standard astronomical unit.

The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
