A Parsec is 3.26 Light years.
It is defined as a right trangle that is 1 AU on the shortside, with the far angle being 1 arcsecond (1/3600 degrees, or .0002777... degrees), so the close angle is 89.9997222... degrees.

How is PARsec calculated?
1Define the parsec. Let ABC be a right triangle with the vertices A, B, and C such that A is the sun, B is the earth and C is a point in space. The angle B is the right angle and angle C has a measure of 1 second. The length of side BC is equal to 1 parsec.2Determine the measurements of the triangle. There are 60 seconds in a minute and 60 minutes in a degree. Therefore, there are 60 x 60 = 3600 seconds in a degree. Thus, angle C measures 1/3600 degree. The length of side AB is the distance from the earth to the sun, which is 1 astronomical unit (AU) by definition.3Find the length of side BC, which is the distance from the earth to the point in space described in step 1. From trigonometry, we have BC/AB = cot(C) where cot is the cotangent function. Since AB = 1 AU, we can say that BC = cot(C) where length BC will be measured in AU. Therefore, we have BC = cot(C) = cot(1/3600) = 206,265 AU. Thus, BC = 206,265 AU, so a parsec is therefore equal to 206,265 AU.4Calculate the distance BC into miles to get the number of miles in a parsec. BC = 206,265 AU and there are about 93,000,000 miles in an AU, so a parsec is 206,265 x 93,000,000 = 1.92 x 10^13 miles.5Convert 1.92 x 10^13 miles to light years. Light travels 186,282 miles/second, so a parsec is (1.92 x 10^13) / (186,282) = 1.03 x 10^8 seconds. There are about 60 x 60 x 24 x 365 = 31,536,000 seconds in a year so a parsec is about (1.03 x 10^8) / (31,536,000) = 3.26 light years.
Who defined the absolute temperature scale?
The absolute temperature scale was defined by Lord Kelvin.
What is The amount of space between two objects or places?
Distances used for measurments in space include the astronomical unit or AU (average distance from the Earth to the Sun), the parsec (the distance to the vertex of an angle of 1 second of arc subtending one AU) - often rendered more conveniently in kiloparsec Kpc, megaparsec Mpc, etc. - and the light year, or distance light travels in a vacuum in a duration of 1 Earth year. The parsec is about 3.26 light years.
What is a light parsec?
"Light-year" and "parsec" are two units of length used in Astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
What is light year A parsec?
"Light-year" and "parsec" are two units of length used in astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
What happens to parallax as the distance to a star increases?
In that case, the parallax will decrease. It is inversely proportional. The relationship is the following:parallax (in arc-seconds) = 1 / distance (in parsec) In fact, that's how the parsec is defined.
What is longer than a Parsec?
1 kilo parsec
Is the larger a parallax shift the closer an object is?
Yes, that's the way it works. A parallax angle of 1" (arc-second) means that the object is at a distance of 1 parsec (that's how the parsec is defined); at a parallax angle of 1/10 of an arc-second, the object would be at a distance of 10 parsec, etc. A parsec is approximately 3.26 light-years.
How many units does a parsec cover?
1 parsec = 19,173,510,995,000 miles.
How many kilometres are in a parsec?
1 Parsec = 3.08568025 × 1013 kilometers.
How long is a parsec in meters?
1 Parsec = 3.08568025 × 1016 meters.
How many light years make 1 parsec?
1 Parsec = 3.26163626 light years
How many meters in a parsec?
1 parsec is 3.09 x 1016 meters.
When was Parsec - video game - created?
Parsec - video game - was created in 1982.
When did Parsec - video game - happen?
Parsec - video game - happened in 1982.
