The planets in our solar system are extremely varied, ranging from Venus, where temperatures can reach a scorching 471°C, to Neptune, where it plummets to a chilly -201°C. As well as varying in temperature, the planets also have different motions, meaning the length of a day and a year is very different. Now, Exploratorium has put together a handy calculator that lets you see just how old you would be on the other planets.

Simply enter your date of birth, and the calculator will reveal your age in days and years, as well as when your next birthday would be. For example, my birthday is 4 January 1992, meaning that here on Earth I’m 28. However, on Mercury, I would be 118.9 years old and my next birthday would be on September 1 2020, while on Neptune I’d be just 0.17 years old, and my next birthday wouldn’t be until Aug 11 2240! To understand why this is the case, it’s helpful to know how a day and year are actually defined.
