TLEs are available for this object, and for other satellites on these pages.
Click here for a graph of this object's inclination and perigee vs. time, from launch in 1967 to 2020. The orbital period has been roughly constant over that time, but due to the Kozai mechanism, there are big fluctuations in the inclination and eccentricity.
