Well, here we are! This is a new post - and, as you can probably guess, it'll be where I talk about the Solar System. Well, let's get going then!
...The Sun. A giant ball of fire at the centre of the Solar System. (well, technically, it's made of plasma, but fire is a plasma.) It accounts for roughly 99.86% of the mass of the entire Solar System!
At its equator, the Sun has a radius of 695,700 km - 105 times that of Earth! Its temperature is 5,500 °C and its gravity is about 28 times stronger than Earth's. As with the rest of the Solar System, it is roughly 4,600,000,000 years old.
Of course, being by far the brightest object in the sky, the Sun has, for thousands of years, been seen as a deity - it even has its own day! (Which, by chance, is the day I upload my blog posts!) As a G-type star, the Sun is brighter than about 85% of the rest of the stars in the Milky Way, and indeed brighter than most of the stars in the entire observable Universe.
The Sun is a Population I star, meaning it is rich in heavy elements - such as gold, uranium and so on. From measurements of the abundance of elements like these on Earth, it can be inferred that it was perhaps a supernova that triggered the formation of the Sun.
Now, on the topic of supernovae, the Sun will not 'go nova', so to speak, when it reaches the end of its life. Rather, it will expand to 256 times its current size, probably destroy Earth, and then shrink down. And it will definitely not turn into a black hole. The Sun, despite having 99% of the Solar System's mass, is not nearly heavy enough to form a black hole.
But back to now! The Sun is an amazing thing - that can't be denied! It makes all of life on Earth possible - it gives plants energy to grow and be eaten by animals, it warms us and it provides us with light to see by!
...Well, that's all I have to say about the Sun for now. Over the next three days, I think I'll be worked to my limit by this blog - it's Dad's birthday tomorrow, mine the next day and then on Wednesday, there'll be more Pokémon Sun and Moon news! But for today, this is me - saying bye!
