I assume degrees, and then minutes and seconds of degrees.
The 'ERG' is the standard unit for work or mechanical energy.
The SI unit of voltage is the Volt, which is a derived unit equivalent to a Joule/Coulomb.
The metric unit of length is the 'meter'.
The base unit of measure for FAID6000 is each (EA).
the unit used to measure angle is degree. It is also measured in radians.
Since it is so close you would use stellar parallax to resolve the distance to proxima centauri.
The astronomical unit called a parsec is based on the idea of parallax.
The baseline distance is one astronomical unit, the average radius of the Earth's orbit. Measurements of a star's position against the background of distant stars are made at intervals of 6 months, when the Earth is at two different places, to measure the parallax and hence the distance to individual stars. For a parallax of 1 arc-second the distance is 1 parsec, equal to a distance of 3.26 light-years. In astronomical data, stars' distances are quoted in parsecs. In the 19th century Bessel was the first astronomer to measure parallax and so discover that the stars are at distances that are much larger than was thought possible before then. Even the closest stars have a parallax of under 1 second of arc, and until the 19th century the apparent absence of parallax in stars was taken as a major proof that the Earth cannot be in motion round the Sun, and this was quoted by Galileo (among many others) before he adopted the Copernican heliocentric system later.
depends who's measuring and which star. it is a matter of preference. 1. kilometers/miles - relatively nearby star like our sun 2. lightyears - near-medium star like the nearest star except the sun 3. parsecs - medium-far star 4. megaparsecs - very far star there are some others but they are not the usual ones
Yes. The parsec is a unit of distance, or length, equal to about 3.26 light-years, or 3.09 x 1016 meters.
parallax[parallax+second], in astronomy, basic unit of length for measuring interstellar and intergalactic distances, equal to 206,265 times the distance from the earth to the sun, 3.26 light-years, or 3.08×1013 km (about 19 million million mi). The distance in parsecs of an object from the earth is the reciprocal of the http://www.answers.com/topic/parallax of the object. The nearest star, Proxima Centauri, has a parallax of 0.763″ of arc and a distance of about 1.31 parsecs.definition from Answers.com
The mathematical equation which describes how to measure the distance from Earth to the moon using Earth's diameter as a unit of measure is d = Dcot(p/2)/2 Where d is the distance from Earth to the moon, D is the diameter of the Earth and p is the angle of parallax subtended at moon by the diameter of the Earth.
You can use kilometers. Or you can compare it to the radius of our Sun, and say, for example, "This star has 600 times the diameter [or radius] of our Sun."
Light Year is unit for all astronomic distances
Either parsecs or light years (a parsec is about 3.2 light years; it's the distance at which an object shows a parallax of one arc-second when measured on opposite sides of the Earth's orbit).
The distance between stars is typically measured in light years, which represents the distance that light can travel in one year. This unit is used because distances in space are vast and need a large unit of measurement.
As far as I am aware, CO is not a unit of measure.
