Kepler's Laws: Find the Mass of the Sun
Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.
Calculate Your Weight on Another Planet
The 'Space Weight' Calculator
Ever wondered how heavy or light you would feel on another planet in our Solar System?
Gravity Simulator
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?
The 'Space Age' Calculator
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.
Order the Orbit
These orbit maps of the inner Solar System are in the wrong places on the calendar! Can you rearrange them so each image is on the correct date?
Anu Ohja
Early Life
Anu grew up in the 1970's and was captivated by the early crewed missions to space. As a teenager he saved his pocket money and cash from his paper round to buy a telescope. His memory of seeing Saturn's rings for the first time still makes him feel emotional. Anu didn't know what he wanted to be when he grew up, but knew he wanted to keep on learning.
