Comment on Sun God

Im struggling to parse this. The picture of the sun with the tiny dot when compared with the artists impression you posted. It just wont click together. How can the sun appear so big from the telescope compared to mercury but be so small from mercury’s perspective?

Yep, zoom and narrow aperture really messes with perspective.

It’s kind of opposite of the tilt shift photos that make real life things look fake.

If someone is struggling with it still, think about the moon.

On the surface of the moon, the sun looks basically like from the earth, small disk in the sky.

From lunar eclipses we know that just from 300.000km away (on earth) the moon looks just as big as the sun.

Now imagine you travel just a couple million km further away, the moon will look smaller and smaller, while the sun stays almost the same (as the distance to the moon will be 10 times bigger and the distance to the sun will increase by like 2%). If you are just 3 million km away from earth the moon will be a small-ish dot in front of the sun (it would cover about 1% of the suns disk, if my math maths out).

For context, the moon and mercury are quite comparable in size.
