Planet

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!

An exoplanet is a planet which orbits a star that is not our Sun. The first exoplanet was discovered in 1992. It was found in orbit around the pulsar PSR 1257+12.

Our Solar System contains the Sun, 8 planets, and many small objects like dwarf planets, moons, and

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?

Ever wondered how heavy or light you would feel on another planet in our Solar System?

Is gravity the same everywhere? Experiment with how the ball reacts in each of the Solar System locations by dropping or throwing the ball. How similar or different is each location to Earth?

Every year, the Earth completes one orbit of the Sun, and every year, you have a birthday! And during a year, the Earth rotates 365 times on its axis and we experience 365 sun rises and sun sets.
