International Date Line
Alaska
The International Date Line is located near Homer, Alaska.
The Prime Meridian
-- Each meridian ( 'line' ) of longitude represents all of the infinite number of points on the Earth's surface that have that one specific longitude. -- Each parallel ( 'line' ) of latitude represents all of the infinite number of points on the Earth's surface that have that one specific latitude.
150 degrees west longitude is a geographical coordinate that represents a line of longitude located 150 degrees west of the Prime Meridian, which runs through Greenwich, England. This line passes through the Pacific Ocean and intersects various regions, including parts of Alaska and the islands of the South Pacific. It is used in navigation and mapping to help determine precise locations on Earth.
The 55th latitude and 55th longitude meet at the intersection point in the Pacific Ocean near the Alaska Peninsula, southwest of Alaska. This intersection represents the coordinates where the latitude and longitude lines cross each other.
The only US state that intersects with 150 west longitude is Alaska. Alaska's longitude spans from 130°W to 172°E. Alaska's border include a series of islands falls into the eastern hemisphere but the International Date Line (IDL) was drawn west of 180° to keep the whole state within the same legal day.
Alaska is in both the Western hemisphere and Easter hemisphere. Alaska's Aleutian Islands stretch across the 180º line of Longitude, which divides the Earth into Eastern and Western hemispheres. BarDev
The line of longitude at 135 degrees west primarily runs through the state of Alaska, specifically in the Aleutian Islands. It also crosses a small portion of the state of Washington. The majority of the land along this longitude is in remote areas, particularly in Alaska.
This longitude cuts right through the heart of Alaska and through French Polynesia. It also cuts through a part of Antarctica.
The state of Alaska extends over all longitudes between 172.5° east to 130° west. The meridian of 150° west crosses the state. No other state in the US has any territory at that longitude.
This is the nominal meridian of the International Date Line, the point from which calendar days are said to begin (generally since 1917). The line does not follow the longitude scrupulously, being altered westward for the Aleutian Islands of Alaska, and eastward for :RussiaKiribati IslandsFiji IslandsTonga IslandsKermadec Islands (New Zealand)(see related question)
