The Sun is by far the largest object in the solar system, containing over 99% of the mass. It has a diameter over 100 times larger than Earth and generates energy through nuclear fusion of hydrogen into helium. Light from the Sun takes approximately 8 minutes to reach Earth. While the visible surface of the Sun appears solid, it actually consists of several layers including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Solar activity like sunspots, solar flares, and coronal mass ejections can impact power grids and communication systems on Earth. Astronomers study the Sun to better understand stars and how changes in solar output impact Earth's climate and atmosphere.

THE SUN: OUR STARASTRONOMY REPORTERS: RHODADE JUAN LINDYLBRIONES B.E.ED.
TRUE OR FALSE 1. Light from the Sun reaches Earth in around 8 minutes. TRUE FALSE 2. The Sun visible to our eyes does have a solid surface such as that of the Earth or the Moon. TRUE FALSE THE SUN

SUN o The largest object in the Solar System. o It contains more than 99.8% of the total mass of the Solar System. o At around 1,392,000 kilometers (865,000 miles) wide, the Sun’s diameter is about 110 times wider than Earth’s. o The Sun generates huge amounts of energy by combining hydrogen nuclei into helium. This process is called nuclear fusion.
o The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else (metals) amount less than 2%. This changes slowly over time as the Sun converts hydrogen to helium in its core. o A mean distance from Earth of about 93, 000, 000 miles or 150, 000, 000 kilometers. o The sun is 93 million miles from earth, yet it's 270,000 times closer than the next nearest star. o The Sun's age is estimated to be around 4.5 billion years.

The Sun Our Star
MODERN ASTRONOMERS, PHYSICIST, AND ENGINEERS DO THEIR BEST TO STUDYTHE SUN, BECAUSE: 1. It is the most inexhaustible source of present, potential energy; it is free and non- polluting. 2. It is the only star near enough to observe in detail, it can be determine what other stars are like. 3. Changes in the sun’s energy output affect the earth’s climate, weather, atmosphere, and power transmission and communication system.
THE THREE PHENOMENA THAT INDICATE VIOLENT ACTIVITY OF THE SUN 1. SUNSPOT 2. SOLAR FLARES 3. CORONAL MASS EJECTION or CME
SUNSPOT o Are temporary, dark, relatively cool blotches on the Sun’s bright photosphere. o The largest sunspots are visible at sunrise or sunset or through a haze. o A typical sunspot is roughly twice as big as Earth. The largest sunspots maybe bigger than the ten Earths. o The Umbra or Core is about 4200 K of temperature while the Penumbra, the outer gray part of a large spot, is a few hundred degrees cooler than photosphere.
SOLAR FLARES o Sudden, tremendous, explosive outburst of light, invisible radiation, and material from the sun o One great solar flare may release as much energy as the whole world uses in 100, 000 years. o Flares are short-lived, typically lasting a few minutes and the largest last few hours. o Flares seem to be energized by strong local magnetic fields.
The Sun Our Star
CORONALMASS EJECTION o Blast plasma out from the corona. o It include prominences, fiery arches of ionized gases on the sun’s limb that rise tens of thousands of kilometers up.
TWOEFFECTS OF SOLAR ERUPTION TO MODERN TECHNOLOGY ON EARTH 1. Disruption in power transmission 2. Disruption in radio communication
