Your age on other planets
A "year" is one trip around the Sun, and every planet takes a different amount of time to make it. Enter your birthday to see how many birthdays you would have had elsewhere.
Based on sidereal orbital periods (Earth = 365.256 days). Pick a date to update the results.
Your weight on other worlds
Your mass stays the same everywhere, but your weight, the force gravity exerts on you, changes from world to world.
Surface gravity values from NASA planetary fact sheets. For the gas giants, "surface" means the cloud-top level where pressure equals 1 bar.
How long does light take?
Light is the fastest thing in the universe, at 299,792 km every second. Across the cosmos, even light needs a while.

Planet distances change constantly as everything orbits; figures are averages or extremes as labelled. The Voyager 1 estimate is approximate and measured from the Sun.
