Find out how much — or how little! – you might weigh on other planets, some of the moons that orbit them, and even the Sun.

Your weight is a measure of the pull of gravity, and gravity depends on the size of the object you're standing on — and of course, the size of you. Why spend hours doing research and using complex mathematical formulas? Now you can relax and let the iPad do the work!

This easy-to-use interface supports both pounds and kilograms, and features brilliant photography and fascinating information about objects in the Solar System, including size, surface temperature (when visiting the outer planets, bring a sweater), and how long it would take to walk there (if you want to try, I suggest wearing comfortable shoes).
