Which state extends past the 180th meridian into the Eastern Hemisphere?

Alaska is the only state that extends past the 180th meridian into the Eastern Hemisphere. The 180th meridian is significant because it denotes the line where the Eastern and Western Hemispheres meet. While most of Alaska is located in the Western Hemisphere, a small part of the Aleutian Islands crosses the 180th meridian into the Eastern Hemisphere. This unique geographical situation is a result of Alaska's large size and its position relative to the international date line, which also runs near the 180th meridian.

In contrast, the other states listed—Kansas, Hawaii, and California—are entirely situated within the Western Hemisphere. Kansas is centrally located in the continental United States, both Hawaii and California are well to the southeast of the 180th meridian, so they do not cross into the Eastern Hemisphere. This makes Alaska particularly interesting in terms of its geographical alignment with global hemispheres.
