He made accurate observations of its distance from the nine principal stars in
Casseiopeia , and proved that it had no measurable parallax . Later he employed
the same method with the comets of 1577 , 1580 , 1582 , 1585 , 1590 , 1593 , and

He proved that if a body be projected with any velocity in free space , subject only
to a central force , varying inversely as the square of the distance , the body must
revolve in a curve which may be any one of the sections of a cone — a circle ...
