1722 Goffin, provisional designation 1938 EG, is a stony asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle on 23 February 1938.[7]

The S-type asteroid orbits the Sun at a distance of 2.4–2.6 AU once every 4 years (1,456 days). Its orbit shows an eccentricity of 0.05 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 28.8 hours and an albedo of 0.22.[4][5]

The minor planet was named in honour of the Belgian amateur astronomer Edwin Goffin (b. 1950), who has made extensive computations involving minor-planet orbits, and whose initials are indicated by the body's provisional designation, 1938 EG.[2]
