Our sun is made up of ¾ hydrogen and the rest is mostly helium. Our sun’s surface is between 5,027-5,727 degrees C. In examining our Milky Way galaxy, scientists think that there are nearing seven billion stars that are similar to our sun. We could put 1 million Earths inside the sun. The classification of a star isn’t based on size but instead it relates to the surface temperature. This solar nebula rotated and created a gravity that was so intense that it collapsed. http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=283424434 We look at the sun rising every day. The ancient Romans took much of their culture from the Greek and as their empires progressed they worshipped a number of sun gods. The ancient Greeks thought that the sun was a handsome god that they named “Helios.” He was the son of the Titans Hyperion and Theia, and brother to the moon goddess Selene and goddess of the dawn, Eos. [3] At its core, the sun’s temperature is about 15 million degrees Celsius (about 27 million degrees Fahrenheit). The sun generates a magnetic field of electric currents that radiates throughout the solar system. So it’s a good thing that our sun is the right size to have a longer life. The Sun keeps our planet warm enough for living things to thrive. The Sun is part of a system of hundreds of billions of stars - a galaxy - called the Milky Way. eval(ez_write_tag([[300,250],'planetsforkids_org-medrectangle-1','ezslot_11',176,'0','0']));report this ad. An introduction to the Sun and its role in our galaxy. How you can tell the time of day from shadows cast by the Sun. It is a huge ball of very hot gas. Energy that is being created in the sun takes millions of years to travel from the core inside and make its way to the surface of the sun. The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. However, it is due to the energy from the sun that life on Earth is possible. Officially, the sun is classified as a G2 type star, based on its temperature and the wavelengths or spectrum of light that it emits. Sun Facts for Kids. The Sun accounts for 99.86% of the mass of our entire Solar System. The Sun is 870,000 miles (1.4 million kilometers) across. At its centre the temperature is 15 million degrees centigrade. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer. What would the sun look like in that combined image? Have you ever wondered why your shadow is longer sometimes and shorter others? The Sun is a star found at the center of the Solar System. Energy at the core is then carried out by radiation and that bounces around for about 170,000 years in the radiative zone until it gets to the top of the convective zone. The sun’s mass is around 70.6% hydrogen and 27.4% helium. The Sun is a yellow dwarf star at the center of our Solar System. When talking about stars, it’s important to remember that the larger the star, the shorter its life will be. All rights reserved. A majority of the material was pulled into the center to form the sun and its mass accounts for 99.8% of the mass of our entire solar system. We started by singing 'The sun has got his hat on' then did different activities through the Powerpoint like taking it in turns to be the sun and the earth moving around it, and trying on different sunglasses and hats. Explain the movements of the Earth, moon and sun by developing models Time Required: 90 minutes A stationary dot? This was due to the fact that Helios was considered to be a Titan, part of the highest order of gods, and Apollo was a member of the gods known as the Olympians. Unlike rocky planets, there isn’t any kind of solid surface of the sun because its outer layer is gas. As we continue to explore the galaxies we are finding that our sun is just one of many trillions of stars that are in the universe. It is a huge ball of very hot gas. The sun's heat also creates a vast amount of energy on our planet, in fact, pretty much all energy created and used on Earth derives from the sun in one way or another. It continued to spin fast and faster and then flattened into a disk-shape. When that happens it will expand and grow and eventually engulf Mercury, Venus, and Earth. We have carried the name “sol” forward to today as it represents anything related to our sun, including our solar system. Examples given include how the sun makes cars able to function and why crisps are a product of the sun. It takes our sun 225-250 million years to complete an orbit around the Milky Way galaxy. The Sun is a main-sequence G2V star (or Yellow Dwarf). The solar system consists of our sun, which is a star, and all that its gravity affects. eval(ez_write_tag([[580,400],'planetsforkids_org-medrectangle-3','ezslot_5',601,'0','0'])); There are also dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids of all shapes and sizes.eval(ez_write_tag([[336,280],'planetsforkids_org-medrectangle-4','ezslot_8',198,'0','0'])); Our sun is a hot ball of gases that is the very center of our solar system. Scientists have indicated that our sun has gone through around half of its lifecycle and will continue to shine for an additional 6.5 billion years before it eventually shrinks and becomes a white dwarf star. Since the sun rotates, the stream of particles blows out in a spiral that is called the “Parker Spiral.” When these electrical particles slam into planets and other celestial objects it can cause damage unless stopped or veered off by atmosphere, magnetic fields, or both.
