mass of sun = 2*10^30kg
radius of sun =7.0*10^8m
radius of orbit of venus = 1.08*10^11m
radius of orbit of earth=1.50*10^11m
with this info
and what is angular size definition pls

I see. I believe there is also some astronomy involved here as I didn't do astronomy with AQA and so I really don't know what angular size is. Perhaps you will cover this if you do OCR but here is the module I found online. The question is on page 213.

Use Kepler's third law

Thanks will have a go.

But then you would have to know the period of its orbit and its mass.

yes I go that lol, I have no idea how supposed to find the mass of venus from the question?

You could find it (according to the bear's reasoning, the period of Venus is equal to that of earth) but then that wouldn't be much of help. It definitely would if the density of sun could be assumed to be almost equal to the density of venues.

I see, thank you for your help
