Venus and Jupiter will be visible near each other in skies around the world tomorrow and Wednesday in a rare conjunction event. The planets, which are hundreds of millions of miles from each other, will for a short period of time seem to be galactic neighbours, passing so close they seem to merge. It will be the closest conjunction of the two planets until August 2016.
The two planets are the brightest in the night sky as seen from Earth.
The line-of-sight illusion is caused when the orbits of Venus and Jupiter line up on the same side of the sun as seen from Earth. As Venus orbits in 225 days, Earth in 365 and Jupiter in 4,330, the chance of such as alignment occurring is fairly rare. The next in August 2016 will be visible only from certain latitudes, while they will not be seen in UK skies like this again until November 2019.
