Knowing that one parsec is about 3.2 light years and the Sun is 8 light-minutes away what is the Sun-Earth distance in parsec?

8 light min=3.2x8/(365x24x60)=4.87E-5 Parsec

What is a parsec a measure of?
a unit of distance used in astronomy, equal to about 3.26 light years (3.086 × 10^13 kilometers). One parsec corresponds to the distance at which the mean radius of the earth's orbit subtends an angle of one second of arc.
What is larger a parsec or nanometer?
A parsec is a bit larger. Quite a big bit larger. I heard it said that a nanometre is how much an aircraft carrier sinks when a seaguall lands on it. This isnt very much. A parsec is the distance you would cover if you were travelling at 186,000 miles per second for about 3 and a quarter years. These are approximate but you get the idea.
How many meters in a parsec?
1 parsec is 3.09 x 1016 meters.
Is there anything bigger than a parsec?
There are bigger forms of parsecs. A kiloparsec is basically a parsec times 1000 or 1000 parsecs. For example a parsec is approximately 3.26 light years, a kiloparsec is about 3260 light years. So what ever number you have in parsecs you just times that by 1000 and that will give you kiloparsecs. "Kilo" means a thousand basically. There are also 2 other forms of measurements that are even bigger than a parsec and a kiloparsec. These measurements are megaparsecs and gigaparsecs. A megaparsec is a million parsecs and a gigaparsec is a billion parsecs. Astronomers usually measure the distance between galaxies in megaparsecs. Gigaparsecs can be used for galaxies or something that is much much farther away in our universe. Just to show you how big of a measurement a gigaparsec is; a gigparsec is approximately 19173528100000000000000 miles long. How do you say this number you ask? This number is one sextillion, nine hundred seventeen quintillion, three hundred fifty-two quadrillion, eight hundred ten trillion miles. The gigaparsec is the largest form of measurement that I know of. I thought that light years were long... King Kong aint got nothin on gigaparsecs.
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 are the two words that when put together derive the term parsec?
A parsec is a distance corresponding to a parallax of one arcsecond. The two words that form "parsec" are parallax and arcsecond.
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.
Is parsec a linear distance measure?
Yes. The parsec is a unit of distance, or length, equal to about 3.26 light-years, or 3.09 x 1016 meters.
How big is one parsec?
3.08568025 × 1013 kilometers 3.08568025 × 1013 kilometers
The distance of 3.3 million light years is also termed?
A parsec
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 equals 3.8 light years?
That's a "parsec". It's the distance, measured perpendicular to the ecliptic plane, of an object that exhibits a parallax against the distant background stars of one arc second in six months.
Which distance measurement is most useful in measuring the distance between stars?
There are two in common use; the "light year", which is the distance that light travels in one year, and the "parsec". The parsec is a "parallax-second of arc", the distance that an object would be from Earth if it appears to be separated by one second of arc as viewed from one side of the Earth's orbit and from the other side of the Earth's orbit. The "parsec" is approximately equal to 3.26 light years. For intergalactic distances, many astronomers use the "mega-parsec", one million parsecs distance, abbreviated as "Mpc".
What are the distances represented by a light year an astronomical unit and parsec?
A light year is the distance that light will travel in one year. A parsec is short for parallax second, which is also a measure of distance.Answer 1 Parsec = 3.26163626 light years 1 light year = 0.30659458 Parsecs
What is the distance of star sirius from eath?
About 8.6 light-years, or 2.6 parsec.
How far is a paesec?
A parsec is a measure of distance in space equal to about 3.26 light years.
