720 Bohlinia is a minor planet orbiting the Sun that was discovered by Franz Kaiser, a German astronomer in 1911. It is named for Swedish astronomer Karl Petrus Theodor Bohlin, to mark his 65th birthday.[3] He had worked on the orbits of asteroids.[4]
It is one of the Koronis family of asteroids. A group of astronomers, including Lucy d’Escoffier Crespo da Silva and Richard P. Binzel, used observations made between 1998 through 2000 to determine the spin-vector alignment of these asteroids. The collaborative work resulted in the creation of 61 new individual rotation lightcurves to augment previous published observations.[5]
Binzel and Schelte Bus further added to the knowledge about this asteroid in a lightwave survey published in 2003. This project was known as Small Main-belt Asteroid Spectroscopic Survey, Phase II or SMASSII, which built on a previous survey of the main-belt asteroids. The visible-wavelength (0.435-0.925 micrometre) spectra data was gathered between August 1993 and March 1999.[6]
