☀️ Welcome to the Sun
🌞 The Sun is 99.8% of everything in the solar system — all the planets, moons, and you are the leftover 0.2%.
🔥 It isn't on fire — it glows by squeezing atoms together, turning 4 million tons of itself into light every second.
So — how many Earths do you think would fit inside the Sun?

⭐ Fun fact: The Sun is 400× wider than the Moon — but also 400× farther away. That's why they look exactly the same size in your sky, and why eclipses work.
🔍 Still true scale. Yes, even the Sun looks small from far enough away.

We admire the perseverance, astronaut.
But space is ridiculously big — let us save you some scrolling.
