'Potato' Earth map tells us about gravity levels

Image of the Earth with the different colours - the colours show how the pull of gravity varies in different places.

Potato Earth gives gravity info

It might look like a giant potato in space, but this new model tells us how gravity varies around the Earth.

A satellite collected data showing how gravity - the force that keeps our feet on the ground - is strongest in the yellow areas, and weakest in the blue.

It can help scientists understand how gravity affects things like earthquakes, oceans and climate change.

But don't worry, it doesn't mean you'll float up into the air in different parts of the world!
