I am just curious what record is fastest orbit around the Earth. Although I suppose there are three different metrics one could use to measure what does one mean by fast so here are the three I thought of.
- Shortest Orbital Period
- Fastest Ground Speed
- Fastest Orbital Velocity
If someone could give me a quick answer to any or all three of those categories that would be great. Would also be awesome to see the fastest orbit for manned and unmanned spacecraft (separately). If anyone could point me to the information that would be awesome!
