Which strait separates Russia from Alaska?

The Bering Strait separates Russia from Alaska.

The Bering Strait is a narrow maritime passage between the Chukchi Peninsula of Russia and Alaska’s Seward Peninsula in the United States. At its narrowest point, the strait is about 82 kilometres wide. It connects the Arctic Ocean’s Chukchi Sea with the Bering Sea, which opens toward the Pacific Ocean.

The Diomede Islands sit near the middle of the strait. Big Diomede belongs to Russia, while Little Diomede belongs to the United States; the international boundary runs between them. Because of the date line, the islands are sometimes nicknamed Tomorrow Island and Yesterday Isle, although the labels are informal.

The strait is named after Vitus Bering, a Danish-born explorer who led Russian expeditions in the 18th century. During Ice Age periods when sea levels were lower, the Bering land bridge connected Asia and North America. That ancient region, often called Beringia, is important in research about the peopling of the Americas.
