In an early (1915-1919) use of globular clusters in what we would now call a study of galactic structure, Harlow Shapley derived distances for many globulars, and found that the distribution of globulars was centered at about 15 kpc (kiloparsecs, ...
In the Milky Way Galaxy, wherein the Earth is located, distances to remote stars are measured in terms of kiloparsecs (1 kiloparsec = 1,000 parsecs). The Sun is at a distance of 8.5 kiloparsecs from the centre of the Milky Way system.
Any objects in the Galactic disk that are more than a few kiloparsecs away from us are hidden from our view by the effects of interstellar absorption.
Consider a star that is one kiloparsec closer to the center of the galaxy than our Sun. Is its orbital speed (around the Galaxy) greater or less than the Sun's? Does it take more or less time to complete one orbit of the galactic center?
Using a refined approach, Kapteyn in 1920 arrived at the picture of a small (diameter about 15 kiloparsecs) ellipsoid galaxy with the Sun close to the center.
7-m aperture, which will carry out a form of parallax detection on stars out to a distance of about 10 kiloparsecs, where one kiloparsec is 1000 parsecs and 1 parsec is 3.26 light years.
There is a wide range in size and mass for elliptical galaxies: as small as a tenth of a kiloparsec to over 100 kiloparsecs, and from 107 to nearly 1013 solar masses. This range is much broader for this galaxy type than for any other.
At an estimated distance of 30,000 light years (10 kiloparsecs) from Earth, the structure lies well within the confines of the Milky Way Galaxy.
For the inner few kiloparsecs of the elliptical galaxies, the velocity dispersion = 220 × (L/L*)0.25, where L* is a characteristic galaxy luminosity (around 10 billion solar luminosities). This is known as the Faber-Jackson relation.
For even greater distances there are kiloparsecs and kilo light-years (1 kiloparsec = 1000 parsecs, 1 kilo light-year = 1000 light-years) and for very great distances there is the mega parsec (a million parsecs) and mega light-years (a million ...
On larger scales, structures in the M87 jet a kiloparsec from the core have been found to show transverse velocities of 0.3 - 0.
6 kiloparsecs (25,000 ly) away from the Earth[1] in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius where the Milky Way appears brightest. There is a supermassive black hole at the Galactic Center of the Milky Way.[2] ...
While the scale of our Galaxy is thousands of parsecs, or kiloparsecs (kpc), the scale of the distances between the galaxies is millions of parsecs, or megaparsecs (Mpc).
In the 1958 paper, Abell estimated the physical scale to be roughly 830 kiloparsecs, but this was based on an (incorrect) estimate of the Hubble constant as 180 kilometers per second per megaparsec.
parsec
The distance to an object which has a parallax of one arc second. It is equal to 3.26 light years, or 3.1 x 1018 cm (see scientific notation). A kiloparsec (kpc) is equal to 1000 parsecs. A megaparsec (Mpc) is equal to a million (106) parsecs.
1 arcseconds is at a distance of 10 parsecs, and so forth. A parsec is equal to ~3.262 lightyears (3.09 x 1016 m) or 206,265 AU. Multiples of this unit are kiloparsecs (kpc) = 103 pc and megaparsec (Mpc) = 106 pc.

They are thus useful in determining distances to the globular clusters within which they are commonly found to a distance of about 200 kiloparsecs. Sub-types are classified according to the shape of their light curves.
Ellipticals range in size from the relatively rare Giant Ellipticals, which can be as big as a Megaparsec across with a trillion stars, to the very common dwarf ellipticals which can be as small as a kiloparsec across with a million stars.
