It was discovered on 15 May 1985, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Arizona, United States.
[1] This minor planet was named for Finnish postdoctoral researcher Antti Penttilä (born 1977) at the University of Helsinki, an expert on light reflection and absorption on the surface of small Solar System bodies such as asteroids and cometary nuclei, as well as of the cosmic dust released by cometary comae.
In June 2015, a rotational lightcurve was obtained for this asteroid from photometric observations by astronomer Daniel Klinglesmith at Etscorn Campus Observatory (719), New Mexico.
Lightcurve analysis gave a rotation period of 4.377±0.001 hours with a brightness variation of 0.55 in magnitude (U=3-), indicative of a non-spherical, elongated shape.
[10] Previously, in August 2012, a concurring period of 4.3771±0.0064 hours with an amplitude of 0.46 was determined from observations in the R-band by astronomers at the Palomar Transient Factory, California (U=2).
