Planetary observers mark your calendars: On 4 June 2020, almost exactly 8 years after the last Transit,
Venus will make another close approach, a blistering 29.2' of separation between disk centres at its minimum. This is close enough for the planet's disk to transit the solar corona, and it is close enough for the phase of Venus to become annular. This does not happen often and is a sight to behold. I saw it in 2012 the day after the transit
(EP shot here), and I estimate the period of annularity will extend about a day either side of the conjunction, giving the keen observer a fairly big window of opportunity. Needless to say, extreme care needs to be taken for any visual attempts.
This will be the closest inferior conjunction until the next proper Transit of Venus in 2117
