Sophia Brahe Sophia Brahe Sophia or Sophie Brahe or after marriage Sophie Thott Lange (22 September 1556 or 24 August 1559 – 1643), was a Danish horticulturalist with knowledge of astronomy, chemistry, and medicine. She assisted her brother Tycho Brahe with his astronomical observations. She was born in Knudstrup, as the youngest of ten children, to Otte Brahe "rigsråd," or advisor to the King of Denmark; and Beate Bille Brahe, leader of the royal household for Queen Sophie. Sophia's oldest brother was astronomer Tycho Brahe. Though he was both more than a decade her senior and raised in a separate household, the
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).
