Molniya orbits are of of the most peculiar discoveries made by the old Soviet Union. As shown below, Molniya orbits have a highly eccentric Apogee and Perigee, and consequently they spend a large amount of time in orbit around certain latitudes (north being the most common ones). Molniya orbits were used by the Soviet union for communication satellites since the highly eccentric orbit meant that it spent a large amount of time in the Northern hemisphere, allowing for excellent communications coverage for the Soviet’s geographic position.
