4082 Swann (1984 SW3) is a main-belt asteroid discovered on September 27 1984 by C. S. Shoemaker at Palomar and is named after her granddaughter Carri Susan Swann. The rotational period is 4.03632 hours. It has been examined spectroscopically and appears to have a Class B asteroidal spectrum. Given the distance magnitude and spectral type it probably has an albedo in the range of 20 to 30 yielding a diameter in the range of 25 to 35 kilometers.
