Kepler's 3rd law relates the semi major axis of an orbit with its period (the time it takes for the orbiting body to go around a full cycle). When using units of AU for the semi major axis and years for the period, Kepler's 3rd law can be written as (Orbital Period)^2 =(Semi Major Axis)³ or p² = a³ If Halley's Comet swings around the sun every 75 years, what is the semi major axis of its orbit in AU units?
