- I am 16 years old and my dad is 53 years old. Suppose he was in a rocket and orbiting around the Sun at the speed c-1 m/s ( only one m/s less then the speed of light). My question is : for how long would he need to travel if he was going at speed of c-1 m/s so that both of us would be same age when he comes back home to Earth.

- Purpose of use
- Comparing results of calculations for relative time dilation as experienced on the ISS over various time periods. If anyone is wondering the ISS orbits ~ 7.6604774 km/s, and there are ~ 2592000 seconds in 30 days. According to all this Scott Kelly experienced a time dilation of ~0.01 seconds over the course of his 1 year stay on the ISS compared to us earthbound humans.

- Purpose of use
- I'm a mathematician writing a fiction novel that motivates certain mathematical concepts. I took a course in special relativity in college, but forgot the formula for calculating the time differential experienced by the traveler relative to the observer. Thanks for posting this calculator!
