(astronomy) The mean distance from the Earth to the Sun (the semi-major axis of Earth's orbit), approximately 149,600,000 kilometres ( symbol AU), used to
天文単位（てんもんたんい、英: astronomical unit 、記号: au）は長さの単位で 、正確に 14 9 59 7 87 0 70 0 m である。2014年3月に「国際単位系 (SI) 単位と併用される非 SI 単位」（SI併用単位）に位置づけられた。
It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). This video discusses the distance units of the astronomical unit (AU) and Lithg-Year (LY). The video shows the orbits of planets in the solar system and disc Astronomical unit (AU), a unit of length essentially equal to the actual or total distance between Earth and the Sun, defined as 149,597,870.7 km. Alternatively, the length of the semi-major axis, that is, half the actual diameter , of Earth’s elliptical orbit around the Sun can be regarded. The Astronimical unit (abbr. au or AU) is a unit of length used in astronomy.

The astronomical unit, now denoted with lower case letters ( au ), is a convenient unit of measure for distance in the Solar System being approximately equal to the average Sun-Earth distance. Astronomical Units to Kilometers Conversion Formula [X] km = 149597870.7 × [Y] au where [X] is the result in km and [Y] is the amount of au we want to convert 3.6 Astronomical Units to Kilometers Conversion breakdown and explanation The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). An astronomical unit (abbreviated au) was a unit of length on the interplanetary scale, roughly equal to the (average) distance between Earth and Sol. One astronomical unit was equal to 150 million kilometers, or approximately 93 million miles. The location of Klingon prison ship Captain Gabriel Lorca was being held aboard was located 0.7 au from USS Discovery at the time of its discovery ›› Definition: Astronomical unit.

The video shows the orbits of planets in the solar system and disc The IAU also defines other astronomical units: the astronomical unit of time is 1 day (d) of 86,400 SI seconds (s) (SI is the International System of Units) and the astronomical unit of mass is equal to the mass of the Sun, 1.9891×10 30 kg. Beyond the Solar System the distances in astronomy are so great that using the au becomes too cumbersome. astronomical unit (AU), mean distance between the earth and sun; one AU is c.92,960,000 mi (149,604,970 km). The astronomical unit is the principal unit of measurement within the solar system, e.g., Mercury is just over 1-3 AU and Pluto is about 39 AU from the sun.

The astronomical unit is the principal unit of measurement within the solar system, e.g., Mercury is just over 1-3 AU and Pluto is about 39 AU from the sun. Furthermore, since 2010, the astronomical unit is not yet estimated by the planetary ephemerides. Examples. The following table contains some distances given in astronomical units. It includes some examples with distances that are normally not given in astronomical units, because they are either too short or far too long. Unit of length used to measure the large distances to astronomical objects outside the Solar System.
