The Sun is the [[star]] at the centre of our [[solar system]], which makes up the 99.86% mass of the solar system. The Sun, which is powered by the [[nuclear fusion]] of [[hydrogen]] atoms at its core, serves as the primary source of [[energy]] for the [[life]] on [[Earth]]. The mass of this dwarf star is 1.98892 × 10<sup>30</sup> kg, which is often used as a reference mass (as solar mass M<sub>⊙</sub>) to measure the mass of other stars in the universe. The Sun's current diameter 1.3914 × 10<sup>6</sup> km. Every object in our solar system orbits around the Sun due to its [[gravity]].

== Frequently Asked Questions ==
=== What makes up the energy in the Sun? ===
Roughly 4.6 billion years ago, when the sun started forming out of the collapsed gasses from the solar [[nebula]], the high-density region in the centre created a region of high pressure and high temperature. As the abundant element in that solar nebula was hydrogen, the [[pressure]] and temperature led to the nuclear fusion of those atoms, giving out a massive amount of energy and forming helium atoms. This process is common to all stars, and this is how the Sun is powered too.
=== How is the Sun losing its mass? ===
As the Sun is converting [[mass]] to into energy in its core. This is the primarily the way in which the Sun is losing its mass. Another way is from the solar winds that release [[proton]]s, [[electron]]s and helium nuclei from the surface of the Sun. The Sun is losing its mass at the rate of 4.2 x 10<sup>9</sup> kg per second.
=== What are solar flares? ===
Solar flares are the sudden bright and strong bursts of electromagnetic radiation that frequently occurs on the surface of the Sun.
=== How solar flares work? ===
Solar flares mainly occur due to the change and reconnection of the magnetic fields on the surface of the Sun or the photosphere. When different magnetic fields interact and recombine with one another, massive and bright bursts of electromagnetic radiation erupts. A solar flare usually travels at the speed of light and hence it is quicker than a coronal mass ejection. Though solar flares are usually attributed to the magnetic fields on the photosphere, they are one of the solar phenomena that are still studied in-depth for a better understanding.

-=== What is a coronal rain? ===
-A coronal rain is a phenomenon observed on the surface of the sun, precisely in the corona where the hot plasma condenses and gets attracted by the magnetic fields, thus falling back to the photosphere of the Sun.
