# Is there a difference between a parsec and a secpar?

Yes. A "parsec" is the abbreviation for a parallax-second of arc, a measure of distance.

I have no idea what a "secpar" is, but it might be the abbreviation for some sort of government official, "Secretary of Parking" perhaps.

### How many years is the equivalent of a parsec?

A year is a unit of time, and a parsec is a unit of length, so you can't convert between the two. If you mean light-years, then 1 Parsec = 3.26163626 light years.

### How many kilometers is the astronomical unit parsec?

The astronomical unit parsec is roughly 30,086 trillion kilometers, or 19,17 trillion miles. One parsec is roughly the distance between our solar system and nearby solar systems.

### What two words are the abridgement for a parsec?

parallax second When we observe a star from opposite ends of the Earth's orbit, if there is a parallax difference of 1 arc second, that star is 1 parsec away.

### Which is larger a light year or a parsec?

A parsec is larger. There are about 3.2 light years in a parsec.

### What is the relation between light year 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

### Which is the largest unit of distance the light year or the parsec?

The parsec. 1 parsec is about 3.26 light-years.

### Which is larger a parsec or light year?

A parsec is much greater:1 Parsec = 3.26163626 light years

### The distance between Earth and other stars is measured in?

Either in light years, or in parsec.

### What is relation between light year and parsec showing by equation?

1 parsec is 3.26 light-years. 100 parsecs is 326 light-years. D(ly) = D(pc) x 3.26

### 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.

### Is lightyear or a parsec longer?

The parsec is longer. It's the same distance as about 3.26 light years.

### What is the size of an astronomical parsec?

A parsec is equivalent to about 3.26 light years or about 19 trillion miles.

### How many miles in a parsec?

There are 19 trillion miles (31 trillion kilometres) in a parsec, which is an astromical measurement.

### How many astronomical units are equivalent to a parsec?

About 206,000 given that 1 parsec is 3.06 x 1013 km and 1 AU is 149.6 x 106 km __________________ 1 Astronomical Unit (AU) is the average distance from the Sun to the Earth, about 150 million kilometers or 93 million miles (approximately). We use AU when we talk about distances between objects WITHIN the solar system. One "parsec", or "parallax-second of arc", is the distance that an object would be (from Earth) if we… Read More

### Light years are used to measure distance between stars because?

. . they are a convenient unit. Another convenient unit is the parsec.

### What type of distance is measured by parsec?

The distances between stars or galaxies are typically expressed in parsecs, or alternately in light-years.

### How far is a parsec?

A Parsec is equal to the following: Miles : 19 Trillion Kilometres : 31 Trillion Atronomical Units : 206 Thousand Light Years : 3.26 1 Parsec = 3.26163626 light years

### How many parsec make up a light year?

It's the other way around - how many light years make up a parsec? The answer is: 3.26 light years make up one parsec.

### The unit of distance called the parsec is equal to what distance in light years?

1 Parsec = 3.26163626 light years

### How many light years is a parsec and a kpc?

A parsec is about 3.26 light-years and a kiloparsec (kpc) is a 1,000 parsecs.

### 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 is longer than a light year?

A parsec is longer than a light year. 1 Parsec = 3.26163626 light years

### 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
