Study Notes
The Sun
- The Sun is a star located much closer to Earth than other visible stars at night.
- Composed mainly of hot gases known as plasma, it does not burn but glows like a light bulb.
- The core of the Sun is incredibly dense, with a temperature reaching approximately 15 million degrees Celsius.
- Nuclear reactions in the core release substantial energy, providing essential light and heat for life on Earth.
- Without the Sun, Earth would be unable to sustain life due to extreme cold.
- The Sun lacks a solid surface, surrounded by swirling layers of plasma.
- Prominences are significant loops of gases that extend thousands of kilometers from the Sun and can remain stable for weeks or explode into space.
- Solar flares are bursts of energy from the Sun's surface that can reach Earth, contributing to phenomena such as auroras, visible near the poles.
The Moon
- The Moon itself does not produce light; it reflects sunlight, making it appear illuminated.
- Often compared to a giant rock in space, the Moon has an almost nonexistent atmosphere.
- It revolves around Earth while simultaneously rotating on its axis.
- This synchronous rotation means that the same side of the Moon always faces Earth, as both the rotation and revolution periods are identical.
