Which strait separates Russia from the United States?

The Bering Strait separates Russia from the United States.

It lies between Russia’s Chukchi Peninsula and Alaska’s Seward Peninsula. At its narrowest point, the strait is approximately 85 kilometres wide. The Arctic Ocean’s Chukchi Sea lies to the north, while the Bering Sea lies to the south.

The strait is named after Vitus Bering, a Danish-born explorer who led a Russian expedition through the region in 1728. Two islands sit near its middle: Big Diomede belongs to Russia, and Little Diomede belongs to the United States. The International Date Line passes between them, which led to the nicknames “Tomorrow Island” and “Yesterday Isle.”

During ice ages, lower sea levels exposed Beringia, a broad land bridge connecting Asia and North America. Many researchers consider this region important in theories about the peopling of the Americas, although the exact routes and timing remain subjects of research.
