What does par in parsec means?
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
Steller distances are usually expressed in what units?
Astronomical Units, parsecs, light years, take your pick.
What is the largest practical unit of distance?

Star distance measured by what?
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
Diffusion of materials over long distance is fast true or false?
False, its slower.
What is the color and size of the vega star?
Vega is a white star with an A-type spectrum. Its absolute magnitude (magnitude at a standard distance of 10 parsecs) is 0.5 making it 4 magnitudes brighter than the Sun, i.e. 40 times brighter. Its distance is 30 light years.

What is the distance in the sun?
the sun's distance in parsecs in three-hundred billion parsecs nothing
If a star is 100 light-years away what is its approximate distance in parsecs?
30.659 parsecs
What is the distance modulus for a star that is 1 million parsecs away?
A distance of one million parsecs (approximately 3,262,000 light-years) is commonly denoted by the megaparsec(Mpc).
The parallax of the nearest star Proxima Centauri is 0.769 arcseconds What is the distance to Proxima Centauri in parsecs?
The distance to Proxima Centauri in parsecs can be calculated using the formula: distance (in parsecs) = 1 / parallax angle (in arcseconds). Therefore, the distance to Proxima Centauri is approximately 1.30 parsecs.
What distance is pleiades star cluster?
About 135 parsecs.
What is the distance of the Rigel and the earth?
260 +/- 20 parsecs.
How to convert parsecs into kilometers?
To convert parsecs to kilometers, you can use the conversion factor: 1 parsec = 3.086x10^13 kilometers. Multiply the number of parsecs by this conversion factor to get the equivalent distance in kilometers.
Distance Gamma Hydrea is from earth?
The distance is 41 parsecs (approx 134 lightyears).
What is the distance from the sun to the star vega?
The distance from the sun to the star Vega is roughly 25.3 light years.
Calculate distance to Sirius in parsecs and ligh years?
Sirius is approximately 2.6 parsecs or 8.6 light years away from Earth.
