To give you an overall idea of what you’re seeing here: the Sun is 147 million kilometers away (less than usual because this eclipse happened, coincidentally, very close to perihelion, when Earth was closest to the Sun). The Moon is 390,000 kilometers away. The Sun is about 400 times bigger than the Moon, but also about 400 times farther away, making them look about the same size in the sky. If you’re still having a hard time picturing the scale, take a look at the dark sunspot in the lower right of the big picture: it’s about twice the size of the Earth!
