Fun Facts About The Sun
•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. 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.
•Eventually, the Sun will consume the Earth:
When all the Hydrogen has been burned, the Sun will continue for about 130 million more years, burning Helium, during which time it will expand to the point that it will engulf Mercury and Venus and the Earth. At this stage it will have become a red giant
•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. This means it is the closest thing to a perfect sphere that has been observed in nature.
•Light from the Sun takes eight minutes to reach Earth: Although this energy reaches Earth in a few minutes, it will already have taken millions of years to travel from the Sun’s core to its surface.
•The Sun travels at 220 kilometres 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 complete an orbit of the centre of the Milky Way.
•The distance from the Sun to Earth changes throughout the year: Because the Earth travels on an elliptical orbit around the Sun, the distance between the two bodies varies from 147 to 152 million kilometres.
•The Sun is middle-aged:
At around 4.5 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn for approximately another 5 billion years.
The Sun is currently a type of star known as a Yellow Dwarf
