Overview of the Sun

The Sun, a massive star, plays a crucial role in our solar system. Its immense heat and light not only enable life on Earth but also govern our daily rhythms. As the Earth rotates around its axis, different parts of the planet face the Sun, leading to the alternation of day and night.

Sun facts

• The Sun is a star that provides heat and light, essential for life on Earth.
• The Earth's inhabitants can feel the Sun's heat and see its light.
• Planets revolve around the Sun.
• The Sun is spherical like Earth, but it is much larger, being 109 times wider.

Earth's rotation on its axis causes the alternation of day and night as different parts of the planet face towards or away from the Sun.

Overview of the Moon

• The Moon is much smaller and closer to Earth compared to the Sun.
• The Moon orbits the Earth in a cycle that takes about 28 days, known as a lunar month.
• It reflects sunlight, making it visible to us on Earth, acting like a giant mirror.
• As the Moon travels around the Earth, different portions of its surface are illuminated, causing the Moon to appear to change shape. These changing shapes are known as the phases of the Moon.
