( CNN) North Korea tested an intercontinental ballistic missile Friday that appears to have the range to hit major US metropolis, experts say.

A combination of US, South Korean and Japanese analysis of the launch from Mupyong-ni, near North Korea’s border with China, present the missile flew about 45 minutes, going 3,700 kilometers( 2,300 miles) high and for a distance of 1,000 kilometers( 621 miles ).

If the missile were fired on a a flatter, standard trajectory, it would have major US cities like Los Angeles, Denver and Chicago well within its range, with possibly the ability to reach as far as New York City and Boston, according to David Wright, a missile expert at the Union of Concerned Scientists.
