The closest spot to Earth that experiences very little time dilation is the International Space Station (ISS), which orbits at an altitude of approximately 408 kilometers (253 miles) above the Earth's surface. Due to the relative motion and the weaker gravitational field experienced by the astronauts on the ISS compared to people on Earth, there is a minor but measurable time dilation effect.
The time dilation experienced on the ISS is incredibly small, as the relative velocities and gravitational fields involved are not significant enough to create a substantial time difference. The difference in time between the ISS and Earth is estimated to be around 0.007 seconds per year. In other words, an astronaut spending one year on the ISS would age about 0.007 seconds less than someone on Earth during that time.
It's worth noting that time dilation becomes more pronounced in extreme conditions such as near black holes or in very high-speed motion relative to an observer. However, for practical purposes and in most everyday situations, the time dilation experienced by humans is negligible and doesn't have a noticeable impact on our daily lives.
