7545 Smaklösa, provisional designation 1978 OB, is a stony asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 28 July 1978, by Swedish astronomer Claes-Ingvar Lagerkvist at Mount Stromlo Observatory in Canberra, Australia.
The S-type asteroid orbits the Sun at a distance of 1.7–2.8 AU once every 3 years and 5 months (1,242 days). Its orbit has an eccentricity of 0.23 and an inclination of 7° with respect to the ecliptic. As no precoveries were taken, the asteroid's observation arc begins with its discovery in 1978.
In August 2012, a rotational light-curve was obtained for this asteroid at the Oakley Southern Sky Observatory in Coonabarabran, Australia. The photometric observation showed a well-defined rotation period of 7001143220000000000♠14.322±0.004 hours with a brightness variation of 0.75 in magnitude (U=3). Similar periods of 7001143300000000000♠14.330±0.220 and 7001143002000000000♠14.3002±0.0218 hours were derived at the U.S Palomar Transient Factory in 2014 (U=2/2).
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.1 kilometers in diameter and its surface has an albedo of 0.24, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 4.3 kilometers.
The minor planet was named after the Gotlandic music group Smaklösa. (Literally "Flavourless", but also "Tasteless" or "Tacky". The latter meaning is intended here as indicated by the name of their own record lable "Tasteless Records"). The Swedish band gave a number of concerts on the island of Gotland. They are known for their cleverly phrased lyrics mixed with the local humor of the island. The discoverer of this minor planet has named it after the band, grateful for having attended their concerts in 1998, which are unforgettable to him. Naming citation was published on 8 December 1998 (M.P.C. 33387).
