The connection and interactions between the Sun and the Earth drive the seasons, currents in the ocean, weather, and climate.

  • The Sun contains 99.86% of the mass in the Solar System.
    The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost three quarters Hydrogen, whilst most of the remaining mass is Helium.
  • The Sun is an almost perfect sphere.
    There is only a 10 kilometre difference in its polar diameter compared to its equatorial diameter. Considering the vast expanse of the Sun, this means it is the closest thing to a perfect sphere that has been observed in nature.
  • One million Earths could fit inside the Sun.
    If a hollow Sun was filled up with spherical Earths then around 960,000 would fit inside. On the other hand if these Earths were squished inside with no wasted space then around 1,300,000 would fit inside. The Sun’s surface area is 11,990 times that of the Earth’s.

1. The Sun is a unique object in the Universe.
Our Sun may be unique in the sense that it is the star that supports life on Earth, but other than that, it is anything but unique. Our Sun is a star. 
2. The Sun is about the size of the Moon. This is why we have total eclipses.
The Sun has 1.4 million km diameter, while the Moon is a little less than 3 500 km across. 

I was impressed to learn about the dimension,energy potential and magnetic changes of our Unique Star.

When we look at the sun we never think that it is the star closest to the earth

When the Sun is in a low activity period, we can "see" indirectly the lines of its magnetic field. When the Sun is in a high activity period, there are many sunspots and flares, which involve very intense magnetic fields.

As we go towards the peak of a solar cycle, the Sun is much more active, meaning that there are a lot more sunspots (appearing mostly around the equator) many more flares, Coronal Mass Ejections and other related features.
