Sergei Avdeyev (Сергей Васильевич Авдеев, born 1 January 1956) is a Russian engineer and cosmonaut.

Avdeyev was born in Chapayevsk, Samara Oblast (formerly Kuybyshev Oblast), Russian SFSR. He graduated from Moscow Physics-Engineering Institute in 1979 as an engineer-physicist. From 1979 to 1987 he worked as an engineer for NPO Energiya. He was selected as a cosmonaut as part of the Energia Engineer Group 9 on 26 March 1987. His basic cosmonaut training was from December 1987 through to July 1989. He retired as a cosmonaut on 14 February 2003.

Avdeyev at one point held the record for cumulative time spent in space with 747.59 days in earth orbit, accumulated through three tours of duty aboard the Mir Space Station. He has orbited the earth 11,968 times traveling about 515,000,000 kilometers. In August 2005, this record was taken by another cosmonaut, Sergei K. Krikalev.

Avdeyev is married with two children. He is an amateur radio operator, and his call sign is RV3DW.

Time dilation record

For a long time, Avdeyev held the record for time dilation experienced by a human being.[1][2][3] In his 747 days aboard Mir, cumulative across three missions, he went approximately 27,360 km/h and thus aged roughly 0.02 seconds (20 milliseconds) less than an Earthbound person would have,[4] which is considerably more than any other human being, except Sergei Krikalev.[5] This is due to the special relativistic effect of time dilation and is not properly thought of as time travelling as described by mainstream culture. A common misconception is that the Apollo astronauts hold the record—they did go faster than Avdeyev, but they were only in space for a few days.
