1694 Kaiser, provisional designation 1934 SB, is a rare-type carbonaceous asteroid from the inner regions of the asteroid belt, approximately 16 kilometers in diameter.
It was discovered on 29 September 1934, by Dutch astronomer Hendrik van Gent at Leiden Southern Station, annex to the Johannesburg Observatory in South Africa. It is named for Dutch astronomer Frederik Kaiser.
Kaiser orbits the Sun at a distance of 1.8–3.0 AU once every 3 years and 9 months (1,354 days). Its orbit has an eccentricity of 0.26 and an inclination of 11° with respect to the ecliptic.of 1.8–3.0 AU once every 3.71 years (1,354 days). Its eccentric orbit of 0.26 is inclined by 11 degrees towards the plane of the ecliptic.Kaiser's observation arc begins with its official discovery observation, as no precoveries were taken, and no prior identifications were made.
According to the survey the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kaiser measures 13.84 and 15.68 kilometers in diameter, and its surface has an albedo of 0.241 and 0.166, respectively. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 28.42 kilometers, using an absolute magnitude of 11.46
