The Sun- our star


Our Sun is the star of the solar system. It is a hot fireball that consists Hydrogen and Hillium. When it comes to complete mass component it comprises of accordingly 32,999 Earthmasses. It creates heat and density through it's core which can equally impact in form of nuclear fusion of hydrogen into helium making it a main-sequence star. This releases most amount of energy radiated into space through electromegnetics peakig it into visible light. The sun is G2 type main sequence star that stands between most of hottest of stars and coolest of balanced stars. There are hotter stars than Sun in rarity but dimmer or cooler stars than Sun which are known as Red Dwarfs are in vast amount in Milky way. Sun is also a Population 1 star as it has highr abundance in comparison of metal when it comes to Hydrogen and Helium which is found lesser in amount in Population 2 stars. Scientists believed that elements heavier than hydrogen and helium formed in cor of ancient an exploding stars thereby they had to die before creating more heavier dense particle system. However this was considered that older stars had fewer metals and new stars contained heavy metalistic system, which in case of Sun, is a newer standard of star in which accresion took place in form of heavy metal release due to which Planets were formed, Thence the accresion is the most popular status to give cause of forming the planets in the solar system. Photosphere is considered to be the place where both gases collide and create it's light and energy. The inner part of the sun is also called Corona. The age of sun is 10 times larger than age of any planet in the solar system. The analyses of rotation of our star is counted in a light year. The speed of light on earth count is around 8 minutes and 28 Seconds. Parker solar probe is considered by NASA to be 1st effort that will go closest to this part of the sun. Dwarf sight is the prerequesit stage before a star converts to a black hole.
