The time-travelling astronaut

Stories from Physics for 11-14 14-16 IOP RESOURCES

Russian cosmonaut Sergei Krikalev holds the record for time spent in orbit around the Earth: 803 days. It is calculated that the time dilation caused by his orbital motion means that Krikalev is 0.02 seconds younger than other people born at the same time as him on Earth.
