Describe the phases of the Earth you would see if you were on the Moon

b.) Recall that the delay of the Sun with respect to the stars is 4 minutes per days...
i.) what would the delay be in 30 days?
ii.) thus, if the star Sirius rises in a given winter night at 10:30PM, at what time would it rise exactly 30 days later?
iii.) at what time would Sirius rise exactly 1 year later?

your help is greatly appreciated!

I am only answering the bold type Moon Q.

Assuming you were on face closest to earth or the edge with a view thereof, you would see phases, just like we see for the Moon from here.

But the earth is better looking. Full earth, half earth, crescent earth, waning earth, new earth, full earth....What a mysterious place....

You need to find shade or keep the sun out of your eyes, more so when there is not much earth to see.

But if you were on the backside of the Moon you would not see anything involving Earth phases.

The astronomy buffs can do the rest for you.

You can't do this on your own? It's simple math. It's a sign that looks like this. x, or *, or •.
