Brahe (brä, brä´hê, brä´e), Tycho
1546-1601
Danish astronomer whose accurate astronomical observations formed the basis for Johannes Kepler's laws of planetary motion.

Brahe, Tycho

Brahe, Tycho (1546-1601), Danish astronomer, born in Knudstrup in southern Sweden (then part of Denmark). He made precise, comprehensive astronomical measurements of the solar system and more than 700 stars. Brahe, with only a globe and a pair of compasses, succeeded in detecting grave errors in the standard astronomical tables. In 1572 he discovered a supernova in the constellation Cassiopeia. Brahe found patrons in Frederick II, king of Denmark and Norway, and in Holy Roman Emperor Rudolf II.

Brahe never fully accepted the Copernican system of the universe and sought a compromise by combining it with the old Ptolemaic system. In Brahe's system, the five known planets were supposed to revolve around the sun, which, with the planets, circled the earth each year. Although Brahe's theory of planetary motion was flawed, Johannes Kepler, Brahe's assistant, used Brahe's data in formulating laws of planetary motion.

Science, 1576

Tycho Brahe establishes an astronomical observatory on the island of Hven in the Sound with royal aid, but he will reject the Copernican system of 1543, holding that the five planets revolve about the sun which in turn revolves about an immobile earth.
