I'm sure this is super common knowledge that I just never picked up on, but...

The orbiting altitude of the Hubble telescope is about 350 miles.

But the orbiting distance of the new James Webb satellite will be about 1,000,000 miles. :oops:

I had no idea it was going to be that far out.

Key distinction: Hubble orbits the Earth, Webb orbits the Sun in sync with the Earth.

JWST secondary mirror deployed!

In the telegram chat it was asked whether Hubble could take a picture of JWST right now so I did the math:

Basically you could see JWST but you couldn't resolve it as it would only take up 13% of a single pixel on WFC3 UVIS.

Something I've never once thought about, but makes sense: planets with smaller moons could have eclipses that don't entirely eclipse the sun. I wonder what one would look like if the moon is huge in comparison to the far-away sun? Would it still have an outer glow? :unsure:
