The elliptical path of an orbiting satellite is shown below. Several locations along the path are labeled with letters. Rank these locations in increasing order of speed, beginning with the location of lowest speed. List the letters in increasing order with no spaces or commas between letters. If the speed is the same at all location, simply enter 'Z' into the answer box.
For a satellite moving in an elliptical orbit about a planet (or other central body), the speed of the satellite is observed to increase when the satellite is traveling along its orbital path towards the planet. Conversely, the speed is observed to decrease as the planet is moving along its orbital path away from the planet. In general, the speed of the satellite at any given location along the path varies inversely with the distance from that location to the planet's center.
