Tycho Brahe, a Danish astronomer (1546-1601) paid close attention to uniform circular orbits, which his assistant Kepler, with philosophical differences, rejected. However, it has recently been discovered that giving Earth its own circular uniform orbit in space not only solves many riddles and poorly understood areas of astronomy, it also reconciles Tycho Brahe's original suppositions and suggests that we are living in a binary star system — which Tycho would not have been aware was possible back in his day.
