Abstract In this paper the stability of non-collinear libration points in circular restricted three-body problem has been analyzed considering less massive primary as an oblate spheroid. We have considered two cases to find out the location and stability of non-collinear libration points. In case I, it is observed that there exist infinite numbers of non-collinear libration points on the unit circle centered at oblate body and out of these libration points only those lying in the interval 57˚ ≤ ψ ≤ 60˚ are stable for different values of critical mass parameter µc, where ψ is the angle between m3, m2 and m1 in the same plane. In case II, the non-collinear libration points exist only in the interval 0˚ ≤ φ ≤ 140˚ are stable for different values of critical mass parameter µc, during the analysis we got a collinear libration point which is stable for µc ≤ 0.127284… .
