Which strait separates the eastern tip of Russia from Alaska?

The Bering Strait separates the eastern tip of Russia from Alaska.

It connects the Arctic Ocean’s Chukchi Sea with the Pacific Ocean’s Bering Sea. At its narrowest point, the strait is about 82 kilometres wide, separating Russia’s Chukchi Peninsula from Alaska’s Seward Peninsula.

The strait is named after Vitus Bering, a Danish-born explorer who led a Russian expedition through the region in 1728. Two islands in the middle are known as the Diomede Islands: Big Diomede belongs to Russia, while Little Diomede belongs to the United States.

The international date line passes between the Diomede Islands, producing the popular nicknames “Tomorrow Island” and “Yesterday Isle.” During the last Ice Age, lower sea levels exposed Beringia, a broad land bridge that connected Asia and North America and enabled human migration into the Americas.
