In what is known as a planetary conjunction, the celestial bodies can be seen in close proximity as their orbits around the sun have brought them into alignment.
Last night the planets formed a line in the south-east night sky, but the next such grouping is not due to occur until January 2021.
However, the planets will still be visible until the end of the weekend – and viewers won’t even need a telescope.
Neil Mahrer, founding member of the Jersey Astronomy Club, said: ‘What’s nice is that with both Venus and Jupiter you don’t even need a big ‘scope to get a good look at them.
‘With Venus, because it’s between the sun and us it’s sort of backlit and looks like a half moon at the moment.’
Clear skies are needed to get the best view of the planets, which Mr Mahrer said were best viewed between 6 am and 7 am in the morning.
‘It’s sort of just peaked, but it’s still good to get out and have a look in the mornings,’ he added.
‘If you go out before sunrise, sometime between 6 am and 7 am, and look towards the south-east you can’t help but see what looks like one really bright star – that’s the planet Venus.
‘If it’s clear you will see another bright star just above and that’s Jupiter.
‘Just underneath, more or less forming a straight line, is Mars.
‘To see those three together is unusual.’
The most popular and deeply flawed myth proposed in the more ludicrous corners of the internet is that certain planetary formations threaten to cause earthquakes here on earth.
Earlier this year the web was abuzz with fearful theories and one video that went viral about how an alignment of Mercury, Earth and Jupiter, and their combined gravitational pulls, was due to lead to a magnitude 9.8 earthquake in California on 28 May.
No such event occurred and several commentators pointed out that the moon’s gravitational effect on the earth is many times stronger than all of the other planets combined – no matter what their alignment.
