Find the length of the major axis of​ earth's orbit using​ kepler's third law and the fact that​ earth's orbital period is 365.256 days. use gequals
Kepler`s Third Law: P² = a³ P is a period of the orbit ( in years ) so 365.256 days = 1 year, a is a semi major axis. 1² = a³ a = 1 AU ( astronomical unit ) = 149,597,870.7 km Major axis = 149,597,870.7 km · 2 = 299,195,741.4 km
