Lab 4: Kepler’s Laws (answer sheet) 1. a: semi-major axis b: semi-minor axis c: focus d: center 2. The distance from the center to a focus is 31 millimeters and the length of the semi-major axis is also in millimeters. The numbers are not even and cannot be simplified any further than what they are since 31 is a prime number. The number is 31/102‚ or 31 divided by 102 which results in 0.303921568627451. 3.
