Facts About the Sun
The sun is not made up of any of the three states of matter – solid, liquid, gas. But it is made up of the fourth state of matter – plasma.
Sweating increases the skin’s sensitivity to ultraviolet radiation and thereby increasing the risk of sunburn and sun damage.
Viewing the sun through binoculars may result in permanent damage to the eye. If there isn’t a filter that blocks UV and substantially dims the sunlight.
Sun does not have a definite boundary, and the density of the outer parts decreases exponentially with increasing distance from its center.
The core is the only region that produces appreciable amount of energy through fusion. Remainder of the sun is heated by this energy as is transferred outward through many successive layers, escaping finally though photosphere.
Apart from heat and light, sun also emits a stream of charged particles called the solar wind.
The sun is mostly made up of two gases, 74% hydrogen and 24% helium. Oxygen, carbon, iron, and neon make up the remaining percentage.
One day, sun is going to consume the Earth and this would happen after it burns up all its hydrogen and would take around 5 billion years. During this time, it would expand and engulf Mercury, Venus and Earth, and by this point it will become a red giant star.
