Gravity

A satellite is an object which orbits another. An orbit is the curved path that an object in space takes around another object.

Use our simulator to investigate the effect of gravity on other worlds. Then use your measurements and a bit of maths to calculate the strength of gravity in each location across the Solar System!

Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.

Did you know that what you weigh depends on the strength of gravity? And did you know that the strength on gravity on other planets is not the same as on Earth?

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.
