5 Amazing Facts Everyone Should Know About Our Sun It will do two things as a red giant 1) have a dense core that is the size of a few earth radii and temperature of 50 million k. 2) a tenuous envelope that will have a radius of 150 million km with a temperature of 3500 k. (3226 c). it will enlarge itself past the orbit of mercury and engulf both venus and the earth. 13. the sun has regular cycles of high and low activity. each solar cycle lasts approximately 11 years, and can be tracked by observing the sunspots on the sun’s atmosphere. 14. during the period of high solar activity there is an increase in solar storms, sunspots, solar flares, and coronal mass ejections. 15.
5 Amazing Facts Everyone Should Know About Our Sun In addition to being the central source of light and heat in our solar system, the sun has also been a source of historical, religious, and scientific inspiration. because of the important role the sun plays in our lives, it has been studied more than any other object in the universe, outside our own planet earth. Our sun is a 4.5 billion year old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. it’s about 93 million miles (150 million kilometers) from earth and it’s our solar system’s only star. without the sun’s energy, life as we know it could not exist on our home planet. The sun is the closest star to earth and is 149.60 million kilometers (92.96 million miles) away. [4] at its core, the sun’s temperature is about 15 million degrees celsius (about 27 million degrees fahrenheit). [4] the sun rotates on its axis once every 25.38 earth days or 609.12 hours. [4] a european illustration of the idol of huitzilopochtli. Facts about the sun. the sun is all the colours mixed together, this appears white to our eyes. the sun is composed of hydrogen (70%) and helium (28%). the sun is a main sequence g2v star (or yellow dwarf). the sun is 109 times wider than the earth and 330,000 times as massive. the sun’s surface area is 11,990 times that of the earth’s.

Moving at 450,000 miles per hour, the sun is in orbit around the center of the milky way galaxy, making a full loop every 230 million years. 3. the sun is hot in strange ways. the sun's.
