our sun is in which stage of its life cycle
Sun The Sun is about halfway through its main-sequence stage, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than four million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation. At this rate, the Sun has so far converted around 100 times the mass of Earth into energy, about 0.03% of the total mass of the Sun. The Sun will spend a total of approximately 10 billion years as a main-sequence star.[133] The Sun is gradually becoming hotter during its time on the main sequence, because the helium atoms in the core occupy less volume than the hydrogen atoms that were fused. The core is therefore shrinking, allowing the outer layers of the Sun to move closer to the centre and experience a stronger gravitational force, according to the inverse-square law. This stronger force increases the pressure on the core, which is resisted by a gradual increase in the rate at which fusion occurs. This process speeds up as the core gradually becomes denser. It is estimated that the Sun has become 30% brighter in the last 4.5 billion years.[134] At present, it is increasing in brightness by about 1% every 100 million years.[135]
Sun sign astrology The following table[1] shows the zodiac names in Latin, with their English translation and the individuals' names. It also shows the element and quality associated with each sign. The starting and ending dates of the sun sign are approximate, as they may differ from one year to another (by a day or so), due to the fact that the earth's orbit around the sun is not synchronous with earth's rotation (one year does not comprehend a whole number of days).[2][3] The exact date and time of sign entrance/exit (which is corresponded to the 12 "mid-climates" within Chinese lunisolar calendar) must be obtained with appropriate software or with the help of an ephemeris.
