Which strait separates Asia from North America at its narrowest point?

The Bering Strait separates Asia from North America at its narrowest point.

It lies between Russia’s Chukchi Peninsula and Alaska’s Seward Peninsula. The strait is about 85 kilometres wide at its narrowest, although the Diomede Islands sit between the continents in the middle of the passage. It connects the Arctic Ocean’s Chukchi Sea with the Bering Sea.

The strait is named after Vitus Bering, a Danish-born explorer who led a Russian expedition through the region in 1728. During lower sea levels in the Ice Age, the Bering land bridge connected Siberia and Alaska. This region is central to scientific discussions of the peopling of the Americas.

The International Date Line passes between the two Diomede Islands. Big Diomede belongs to Russia, while Little Diomede belongs to the United States, even though they are only a few kilometres apart.
