Question

why we can see venus only in morning or evening sky and not at noon?

Answer 1

; it is so close to the Sun that its maximum elongation is only about 19 degrees and so sets before an hour after sunset or rises no earlier than an hour before sunrise.
Hope it's help you

Answer 2

we know that Earth rotates on its axis thus when we can see Venus once only from the place where we are standing.
However during noon time the part that faces towards the Venus is the that part of Pacific ocean where there is no land.
Another answer to the question can be that Venus does not reflect the light coming form the sun towards the Earth and in morning and evening time the light is comparatively less so we are able to see other celestial bodies. hopefully this helps you please mark it as brainliest
