If your at an altitude of 20000 km where are you?

Answer 1

At an altitude of 20,000 kilometers, you would be well above the Earth's atmosphere and into the lower reaches of space. Specifically, this altitude exceeds the Kármán line, which is commonly recognized as the boundary of space at 100 kilometers (62 miles). At this height, you would be in the vicinity of low Earth orbit, where satellites and the International Space Station operate. Such an altitude is also significantly higher than commercial air travel, which typically occurs at around 10 kilometers.
