1. An object is orbiting the Sun in an elliptical orbit. When the object was observed at a certain time, the distance from the Sun was r1 = 12 AU and the true anomaly 0, = 90°. After some time, the object was observed again, its distance from the Sun was r2 = 10 AU and the true anomaly is now 02 = 60°. (1) Calculate the eccentricity of orbit, e and the orbital period, T of the object in years. (11) Calculate the distance of the object when eccentric anomaly 60°
