=The Earths Sun is a medium sized star which lies on the main sequence with 90% of the known starts. The Sun is the most prominent feature in our solar system. It is the largest object and it containts about 98% of the total solar system mass. Its interior could hold over 1.3 million Earths, the suns outer visible layer is called the photosphere and has a temperature of 6,000 C. Ever second 700 million tones of hydrogen are converted into helium ashes, in the process 5 million tones of pure energy is released, and therefore as time goes on the Sun is becoming lighter. = =The Sun's diameter is about 100 times that of the Earth, the Suns radiant energies light up our daytime sky and makes all life possible on Earth, even as far away as 93 million miles and the Sun's core can reach temperatures as high as 15 million degress. The Sun is 5 thousand millions years old and 150 million kilometres (or eight light minutes) from Earth.  = =The Sun is one out of billions of stars. The Sun is the closest star to Earth. The Sun  rotates once every 27 days. The Sun is now a middle-aged star, meaning it is at about the middle of its life. The Sun formed over four and a half billion years ago. You may think the Sun will die soon, but it will keep shining for at least another five billion years.   The Sun’s surface is called the photosphere. The temperature of the photosphere is about 10,000 <span style="font-family: Symbol; mso-ansi-language: EN-US; mso-ascii-font-family: 'Kristen ITC'; mso-bidi-font-family: Arial; mso-bidi-font-size: 10.0pt; mso-char-type: symbol; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hansi-font-family: 'Kristen ITC'; mso-symbol-font-family: Symbol; msoansilanguage: EN-US; msoasciifontfamily: 'Kristen ITC'; msobidifontfamily: Arial; msobidifontsize: 10.0pt; msochartype: symbol; msofareastfontfamily: 'Times New Roman'; msofareastlanguage: EN-AU; msohansifontfamily: 'Kristen ITC'; msosymbolfontfamily: Symbol;">°  Fahrenheit. Its core is under its atmosphere. The temperature at the core, or very middle, of the Sun, is about 27 million <span style="font-family: Symbol; mso-ansi-language: EN-US; mso-ascii-font-family: 'Kristen ITC'; mso-bidi-font-family: Arial; mso-bidi-font-size: 10.0pt; mso-char-type: symbol; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hansi-font-family: 'Kristen ITC'; mso-symbol-font-family: Symbol; msoansilanguage: EN-US; msoasciifontfamily: 'Kristen ITC'; msobidifontfamily: Arial; msobidifontsize: 10.0pt; msochartype: symbol; msofareastfontfamily: 'Times New Roman'; msofareastlanguage: EN-AU; msohansifontfamily: 'Kristen ITC'; msosymbolfontfamily: Symbol;">°  Fahrenheit. That’s pretty hot! <span style="font-family: 'Kristen ITC'; mso-bidi-font-family: Arial; mso-bidi-font-size: 12.0pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="font-family: 'Kristen ITC'; mso-ansi-language: EN-US; mso-bidi-font-family: Arial; mso-bidi-font-size: 13.5pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">The Sun’s diameter is about 870,000 miles wide. The Sun is 109 times wider than Earth, and is 333,000 times heavier. That means if you put the Sun on a scale, you would need 333,000 objects that weigh as much as the Earth on the other side to make it balance. =
