The small blue dot is Mercury beginning it’s transit across the Sun on 9th May.
From 9.00pm: Transit of Mercury
We cannot view this event from Ballarat but you can come along and share the experience via a NASA broadcast of the event. Question and answer session.
A transit of Mercury across the Sun takes place when it comes between the Sun and Earth and the tiny planet is seen as a small black dot moving across the face of the Sun. While comparatively rare, at around 13 per century they are much more frequent than similar transits of Venus because Mercury is closer to the Sun and orbits it more rapidly.
Transits of Mercury occur in May or November and the last was in 2006.
Mercury’s transit will take seven and a half hours. The planet will cross the edge of the Sun and begin its transit at 21:12hrs AEST. It will reach mid-point at approximately 00:47hrs AEST, and complete the crossing at 16:42hrs AEST.
Viewing of Jupiter and Saturn if clear.
