This animation demonstrates how the Earth and the Moon were formed.
The inner planets of the Solar System are terrestrial planets while the outer planets are gas giants.
The formation of the Sun and the planets started with the contraction of a dust cloud about 4.5 billion years ago.
The orbits of the 8 planets in our Solar System are elliptical.
The diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.
This animation presents some interesting facts in the field of astronomy.
Jupiter is the largest planet of the Solar System, it has two and a half times the mass of all the other planets combined.
Observatories are often built at high elevations to minimise the effects of atmospheric turbulence
Studying Ceres and Vesta will help us learn more about the early history of the Solar System and how rocky planets are formed.
The three important laws describing planetary motion were formulated by Johannes Kepler.
This animation demonstrates Sir Isaac Newton's three laws of motion that laid the foundation for classical mechanics.
