Astronomers classify the sun as a main-sequence star its composition is roughly the same as other stars, and its temperature and brightness are in the middle of the range of other stars as well in many ways, the sun is just an ordinary star. Mars is the fourth planet from the sun and the second-smallest planet in the solar system after mercuryin english, mars carries a name of the roman god of war, and is often referred to as the red planet because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. A red giant star is a dying star in the last stages of stellar evolution our own sun will turn into a red giant star, expand and engulf the inner planets, possibly even earth. The sun also plays the role of a big anchor, which creates gravity that keeps our planet and the other planets of the solar system in a small space if it weren't for the sun, our planet would simply fly off loose into the universe.
The sun is the earth's main energy source as a matter of fact, life could not exist on earth without the sun its many characteristics include its magnificent size and the processes that carry its energy through the atmosphere to us. Sun - interesting facts about sun the sun is one among the 200 billion stars in our milky way galaxy the sun is one among the 6000 stars, which is visible to naked eye from the earth. The main risk factor for sunburn, premature skin aging, skin damage, and skin cancer is exposure to uv light from the sun more than 90 percent of skin cancers are caused by sun exposure more than 90 percent of skin cancers are caused by sun exposure. The sun also emits a constant stream of particles called the solar wind that bathes all of the planets in radiation this wind is an invisible connection between the sun and all the objects in the solar system, driving seasonal changes.

The sun's surface, or atmosphere, is divided into three regions: the photosphere, the chromosphere, and the solar corona the photosphere is the visible surface of the sun and the lowest layer of. Since we can't see inside the sun, most of what astronomers know about this subject comes from combining theoretical models of the sun's interior with observational facts such as the sun's mass, surface temperature, and luminosity (total amount of energy output from the surface. The centre of the sun is its core which produces all the sun's energy around the core is the radiative zone, which carries the energy out from the core it takes about 170,000 years for the sun's energy to move from the core through the radiative zone to the next layer, the connective zone.
The sun looks like a featureless yellow orb from earth, but it has discrete internal layers the central core, which is the only place that nuclear fusion happens, extends to a radius of 138,000 kilometers (86,000 miles. The sun, as one of the heavenly bodies, has different identifiable parts these parts perform a specific function to keep the sun alive the sun is composed of several layers or regions. Core this is the inner most part of the sun here gravity has squeezed the sun so much that hydrogen compresses together to form helium and release energy through nuclear fusion. Re, also spelled ra or pra, in ancient egyptian religion, god of the sun and creator god he was believed to travel across the sky in his solar bark and, during the night, to make his passage in another bark through the underworld, where, in order to be born again for the new day, he had to vanquish the evil serpent apopis (apepi. Interesting facts about the sun the sun is officially classified as a g-type main sequence star the distance from the sun to the earth is used for a standard unit of measurement called the astronomical unit (au.
Moon facts the moon (or luna) is the earth's only natural satellite and was formed 46 billion years ago around some 30-50 million years after the formation of the solar system the moon is in synchronous rotation with earth meaning the same side is always facing the earth. The sun is by far the largest object in the solar system it contains more than 998% of the total mass of the solar system (jupiter contains most of the rest) it is often said that the sun is an ordinary star that's true in the sense that there are many others similar to it but there are many. The sun is in the main sequence stage right now, slowly using up its hydrogen fuel but at some point, in about 5 billion years from now, the sun will enter the red giant phase, where it swells up.
Temperature of the sun the sun provides all the heat and energy needed in the earth as well as the entire solar system it also generates tremendous energy in the form of light and heat. Sun facts the sun (or sol), is the star at the centre of our solar system and is responsible for the earth's climate and weather the sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. Enjoy these fun sun facts for kids learn how hot the sun is, how long it takes light from the sun to reach earth, what the sun is made of and more read on for a range of interesting facts about the sun the sun is a star found at the center of the solar system it makes up around 9986% of the.
The sun is what is known as a main sequence star that is, a sphere composed primarily of the two gases hydrogen and helium such that certain conditions are met the first condition is that it must have a mass falling within a certain range. Mercury facts mercury is the closest planet to the sun and is also the smallest of the eight planets in our solar systemfor every 2 orbits of the sun, which takes around 88 earth days, mercury completes three rotations of its axis.
The sun is a g-type main-sequence star (g2v) based on its spectral class as such, it is informally and not completely accurately referred to as a yellow dwarf (its light is closer to white than yellow. The sun contains 9985% of the mass in the solar system  scientists have determined that the sun will continue to burn hydrogen collected in its core for another five billion years or so, and then helium will become its primary fuel. A list of important facts about lorraine hansberry's a raisin in the sun, including setting, climax, protagonists, and antagonists.
