It passes through Russian teritory twice (Wrangel Island and the Chukotka Autonomous Okrug) and Fiji, before passing through the Australian portion of Antarctica and ending at the south pole.
http://en.wikipedia.org/wiki/180th_meridian
The longitude of the 180th meridian is 180 degrees, both east and west. It's the meridian opposite the Prime Meridian.
The P.M. joins the north and south poles and passes through Greenwich, England. 180 joins the north and south poles, and splits the Pacific Ocean.
Meridians don't have latitude, since they pass through every latitude. If you name a longitude and a latitude, then you've narrowed it down to a single point, not a line.
The international date line
The major line of longitude located at 180 degrees longitude is the International Date Line.
The boundaries of longitude are from 180 degrees east to 180 degrees west, so a city located at 6 degrees east longitude would be somewhere in Europe, while a city located at 6 degrees west longitude would be in the Americas.
East longitude ranges from 0 degrees to 180 degrees.
That's hard to say, since the largest possible longitude, east or west, is 180 degrees.
The maximum degree of longitude is only 180.
Bering Sea
The international date line
The difference between those two positions is 180 degrees in longitude.
The major line of longitude located at 180 degrees longitude is the International Date Line.
The boundaries of longitude are from 180 degrees east to 180 degrees west, so a city located at 6 degrees east longitude would be somewhere in Europe, while a city located at 6 degrees west longitude would be in the Americas.
Auckland, New Zealand
East longitude ranges from 0 degrees to 180 degrees.
The equator is located at 0 degrees latitude and does not have a fixed longitude. It circles the Earth halfway between the North and South poles.
360 degrees. Longitude runs from 180 degrees East to -180 degrees West.
The greatest number of degrees anyone can be from the prime meridian is 180 degrees. This is because the prime meridian itself is located at 0 degrees longitude, and the maximum longitude value is 180 degrees both east and west. Therefore, any location can be a maximum of 180 degrees away from the prime meridian.
The equator is located at 0 degrees latitude. It is an imaginary line that divides the Earth into the Northern and Southern Hemispheres. The longitude of the equator varies continuously from 0 to 180 degrees as you move around the Earth.
