Earth is already huge by human standards, but next to the Sun she almost disappears. Earth is about 7,926 miles wide, while the Sun stretches to roughly 865,000 miles, making her about 109 times wider. That scale is very well measured, so whenever Earth looks like a tiny speck beside the Sun, it is not an exaggeration, it is close to reality.
Beyond the Sun, size becomes extreme. Stephenson 2-18 is so large that if placed in our solar system, she would extend far past the orbit of Saturn. Then comes TON 618, with a mass around 66 billion Suns. The visible region around it, shaped by light bending and hot gas, is so vast that light would take weeks just to cross it. This comparison is not just about bigger objects, it shows the jump from a small rocky world to a normal star, then to one of the largest known stars, and finally to an ultra massive black hole that sits at the extreme edge of what we observe in the universe.
