The Sun (or Sol), is star at the center of our Solar system and is responsible for the Earth’s climate and weather. The Sun is a nearly perfect sphere with a difference of simply 10km in diameter between the poles and equator. The average radius of the Sun is 695,508 kilometer (109.2 x that of the Earth) of that 20–25% is the core.
20 Interesting Facts About Sun :
- One million Earths might fit within the Sun. If a hollow Sun crammed up with spherical Earths then around 960,000 would fit within.
- On the other hand, if these Earths were squished within with no wasted space then around 1,300,000 would fit within. The Sun’s extent is 11,990 times that of the Earth’s.
- The Sun contains 99.86% of the mass in solar system.
- The mass of the Sun is about 330,000 times larger than that of Earth. It’s nearly 3 quarters hydrogen, while most of the remaining mass is Helium.
- The Sun is a nearly perfect sphere. There’s only a 10 kilometer difference in its polar diameter compared to its equatorial diameter. This implies it’s the closest thing to an ideal sphere that has observed in nature while considering the large expanse of the Sun.
- The temperature within the Sun will reach 15 million degrees Celsius. At the Sun’s core, Nuclear Fusion generates energy , as Hydrogen converts to Helium.
- As usually hot objects expand, the Sun would explode like a large bomb if it weren’t for its huge gravitational force.
- The temperature on the surface of the Sun is nearer to 5,600 degrees Celsius.
- Eventually, the Sun can consume the world.
- When all the Hydrogen has burned, the Sun can continue for almost 130 million more years, burning Helium, throughout which time it’ll expand to the point that it’ll engulf Venus, Mercury and Earth. At this stage it’ll became a Red Giant
- The Sun can one day be about the dimensions of Earth.
- After its Red Giant section, the Sun can collapse, retaining its huge mass, however containing the approximate volume of our planet. When this happens, it’ll be known as a White Dwarf.
- The Sun travels at 220 kilometers per second.
- The Sun is 24,000-26,000 light years from the galactic Centre and it takes the Sun 225-250 million years to finish an orbit of the Centre of the Milky Way.
- The distance from the Earth to sun changes throughout the year. As the earth travels on an elliptical orbit round the Sun, The distance between the 2 bodies varies from 147 to 152 million kilometers.
- The distance between the earth and Sun known an Astronomical Unit (AU).
- The Sun is old. At around 4.5 billion years old, the Sun has already burned off about half of its store of Hydrogen. It’s enough left to continue to burn Hydrogen for about another 5 billion years.
- The Sun is presently a kind of star called a Yellow dwarf.
- The Sun generates Solar wind. This can be a stream of charged particles that travels through the Solar system at about 450 kilometers per second.
- Solar wind happens where the magnetic field of the Sun extends into space rather than following its surface.
Sun is also called as source of Solar system. It is the hottest planet of the all. Some people like sun as it keeps you warm while some hate it as it makes them feel hot.
