Explore the structure of the Sun, observe changes in solar activity by year, and rotate the orbits of the planets to learn about each one.
The home screen features a stylish design with a pyramid-shaped meteor shower animation and quick access to the main sections: “Sun”, ‘Solar Activity Graph’, ‘Planets’ and ‘Quiz’.
On the Sun screen, you can see a realistic visualization of the star and its impact on the entire solar system. Learn what the Sun is made of, how thermonuclear reactions occur, and why solar flares are important to Earth.
Switch to the “Solar Activity Graph” to track how the Sun's activity has changed over the past 25 years. An interactive timeline lets you select specific periods and explore their characteristics, from quiet phases to periods of intense magnetic storms.
