In April 1567, Tycho returned home from his travels, with a firm intention of becoming a scientist. Although he had been expected to go into politics and the law, like most of his kinsmen, and although Denmark was still at war with Sweden, his family supported his decision to dedicate himself to the sciences.

1677 Tycho Brahe asteroid has been characterized as a stony S-type by Pan-STARRS survey, and in the SDSS-MFB (Masi Foglia Binzel) taxonomy, which agree with the overall spectral type for members of the Maria family. In July 2012, a rotational lightcurve of "Tycho Brahe" was obtained by Renata Violante and Martha Leake, that gave a short rotation period of 3.89 hours with a brightness variation of 0.38 magnitude (). According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Tycho Brahe" measures 11.78 kilometers in diameter, and its surface has an albedo of 0.221 (revised 2014-figures).
