Comparisons.jpgComparisons240 visiteSun - Earth: the average diameter of the Sun is about 1,392,000 km, almost 109 times larger than the Earth (12,742 km). This means that we could put 109 Earths side by side to match the diameter of our star.
Stephenson 2-18 - Sun: the largest known star compared to the Sun. We are talking about a radius of 2,158 solar radii (solar radius equals 696,340 km). If we were to place it at the centre of our Solar System, its photosphere would engulf the orbit of Saturn, the lord of the rings.
Ton 618 - Stephenson 2-18: the largest known black hole compared to the largest star. Ton 618 has a diameter of 2606 astronomical units (1 astronomical unit is equivalent to the distance Earth - Sun or 150 million kilometres). To give a better idea, Saturn (used as a comparison before) is 10 astronomical units away from the Sun.
We are ants in the Universe!MareKromiumOtt 13, 2023

Andromeda.jpgIf our eyes were a CCD Camera... (Credits: Stephen Rahn - Tom Buckley-Houston)309 visiteThis is, of course, a photographic COMPOSITION, but the proportions are exact, and what we would see in the sky if the Andromeda Galaxy were bright enough, would be an object almost as wide as 7 full moons.
The Moon seen from Earth, in fact, occupies about half a degree in the sky. M31 on the other hand, over 2 million light years away, is over 3 degrees wide.MareKromiumOtt 08, 2023
