Which strait separates Asia from North America at their closest point?

The Bering Strait separates Asia from North America at their closest point.

The strait lies between Russia's Chukotka Peninsula and Alaska's Seward Peninsula. At its narrowest, the two continents are separated by roughly 85 kilometres of water. The Diomede Islands sit in the middle: Big Diomede belongs to Russia, while Little Diomede belongs to the United States.

The Bering Strait connects the Arctic Ocean's Chukchi Sea with the Pacific Ocean's Bering Sea. During ice ages, lower sea levels exposed Beringia, a broad land region that connected Siberia and Alaska. Many researchers associate this former land bridge with the movement of ancient peoples into the Americas, although the timing and routes remain subjects of continuing research.

The strait was named after Vitus Bering, a Danish-born explorer serving the Russian Empire. It is not the same as the Bering Sea, which is the much larger body of water to its south.
