Venus is always a delightful planet to watch in the evening twilight.
Many people don’t know that Venus undergoes phases, just like the Moon does.
After Venus passed superior conjunction (far side of the Sun) in August 2019, it returned to the evening sky last September as a small 10 arc-second diameter ‘full’ sphere.
Since then, it has been gradually swinging around its orbit, catching up with Earth and as it does so, its phase changes. It currently appears gibbous with a diameter of 18.3 arc seconds.
Its phase will gradually move towards a slender crescent, a much bigger 57 arc seconds in diameter, before reaching inferior conjunction on 4th June 2020, when it will be at its closest distance, passing Earth on the inside before moving back into the morning sky.
The Solar System in motion!
