14 Sep 2012 Without fanfare, astronomers have redefined one of the most important distances in the Solar System. The astronomical unit (au) — the rough

Astronomical unit - a unit of length that is roughly equal to 150 million kilometers, the average distance from the Earth to the Sun. Other units of length used in astronomy are based on the speed of light and the time it takes light to cover a specific distance.

It is..more definition+ The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. astronomical unit (AU): An astronomical unit (AU) is the mean distance between the center of the Earth and the center of the sun. The actual distance varies depending on the time of year, because the Earth's orbit around the sun is not a perfect circle. The mean, or average, separation is approximately 1.4959787 x 10 11 meters, which is Astronomical unit - a unit of length that is roughly equal to 150 million kilometers, the average distance from the Earth to the Sun. Other units of length used in astronomy are based on the speed of light and the time it takes light to cover a specific distance. The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, f..more definition+. A light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances.

The average distance between the Sun and the Earth - 149,597,870.7 km (or 92,955,807 mi) - is known as an Astronomical Unit (AU). The astronomical unit (AU or au or a.u.

Alternately, it can be considered the length of the semimajor axis—i.e., the length of half of the maximum diameter—of Earth’s elliptical orbit around the Sun. For general reference, we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km).

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.

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 AU.

Astronomical Unit - a unit of length used for distances within the solar system; equal to the mean distance between the Earth and the Sun (approximately 93 million miles or 150 million kilometers) AU astronomy unit - a linear unit used for astronomical distances

The astronomical unit (AU) is a unit of length derived from the Earth's orbit. It is the average distance the Earth gets from the Sun on the long axis of the ellipse . Its definition is: the length of the semi-major axis of the Earth's elliptical orbit around the Sun. "Semi-major" means half the long axis.

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. Obtained by the use of parallax and trigonometry, and is defined as the distance at which one astronomical unit subtends an angle of one arcsecond, ie.
