For all budding scientists and astronomers at Great Baddow High School - On Monday 21st December there is set to be a 'great' conjunction.

A conjunction is when planets or other celestial bodies - objects that are natural and visible in the sky - appear as if they are next to one another when we look up from Earth.

This conjunction will be the closest Great Conjunction of Jupiter and Saturn there has been in 397 years.

The two planets will be within 0.1 degree of each other - which is around one fifth of the Moon's diameter.

If you want to catch this rare event you are best looking west after sunset - the two planets will appear in the sky as one big bright double planet.

Some are calling this a 'Christmas Star'!
