How far is it?

How far is it to that galaxy you just looked at?
The answer might be here http://nedwww.ipac.caltech.edu/level5/NED1D/ned1d.html
3,716 distances to 1,210 galaxies with v < 1/8 c

[glenc (Glen)]

For 447 PN try: Distances of planetary nebula (Phillips+, 2004)
http://vizier.u-strasbg.fr/viz-bin/V.../MNRAS/353/589

[glenc (Glen)]

The distances to 520 open clusters are in the:
Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)
http://vizier.u-strasbg.fr/viz-bin/V...J/A+A/438/1163

Distance data for 150 globular clusters are in the:
CATALOG OF PARAMETERS FOR MILKY WAY GLOBULAR CLUSTERS (2003)

Data for nebulae are hard to find:
Try: http://www.atlasoftheuniverse.com/nebulae.html
and: http://galaxymap.org/drupal/node/90

Glen, you're a wealth of information, thanks for that

[glenc (Glen)]

Thanks Adam, I plan to do a spreadsheet soon with all the distances.

[glenc (Glen)]

Here is the spreadsheet for NGC and IC objects.

Champion, thanks Glen!

[glenc (Glen)]

Thanks Paul.
The most distant object in this list is the magnitude 13.6 galaxy NGC 6038 in CrB. William Herschel discovered it in 1787 with his 18.5" reflector.
The galaxy is 1.2' x 1.0' and the attached wikisky.org image is 26' wide. The distance to this object is 460 million light years and it currently transits at about 9:30 pm. The attached SkyMapPro map shows it nearly 8 degrees to the left of M13.

What a great resource Glen

Do you have all your lists saved anywhere online for easy access?

Super job Glen, wonderful resource, thanks!

Cheers -

Most school's mainly teach the solar system when they teach astronomy.
Most observers seem to concentrate on the solar system too.
Maybe that is because of light pollution, faint objects are too hard for most of us to see.
It is only 4 hours to Neptune at the speed of light and 4.3 years to the nearest star (apart from the Sun) alpha Centauri.
Why do we spend most of our time looking in our astronomical backyard?
PS Neptune is only 34' from Jupiter tonight. mu Cap (mag 5.1) is between Jupiter and Neptune.
