The diameter of our galaxy is about 100,000 light years; it contains more than 100 billion stars, one of which is our Sun.
Neil Armstrong, one of the crew members of Apollo 11 was the first man to set foot on the Moon.
During its orbit around the Earth, the visibility of the Moon's illuminated part constantly changes.
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 Moon is the Earth's only natural satellite
The diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.
The apparent movement of the Sun is caused by the Earth's rotation around its axis.
The rise and drop of sea levels caused by the gravitational force of the Moon.
This animation demonstrates how the Earth and the Moon were formed.
