Jupiter and Mercury conjunction – see Solar System's smallest and biggest planets together this week

STARGAZERS will be treated to a close meeting between Jupiter and Mercury this week.

The Solar System's largest and smallest planets will reach conjunction on Friday morning.

That means they'll look like they're almost touching to us Earthly observers.

This celestial event is one for early risers.

You'll need to spot the planets just before dawn on March 5.

Look low on the eastern horizon.

It's best to do this with a pair of binoculars or a small telescope.

Around 45 minutes before sunrise on March 5, Mercury should be slightly above and to the left of Jupiter.

Mercury and Jupiter will be separated by just 0.3°.

Weather permitting, both planets with look like stars shining just above the horizon.

Saturn should also be visible to the right of Jupiter and a lot higher up.

Mercury is the closest planet to the Sun and it reached the outer most edge of its orbit that's visible from Earth in January.

That made it far enough away from the Sun's glare to been seen with the naked eye.

It's been getting increasingly fainter since then and that's why binoculars will come in useful if you want to be sure you spot it.
