If you desire to check out the solar system’s largest planet, the next few nights are the paramount nights of the year to do it.
On Monday night, Jupiter will reach foe, meaning it will be directly opposite the sun and roughly 640,962,549 kilometres from Ground.
Opposition also means that over the next few nights, the superhuman gas planet will be at its brightest, at a magnitude of roughly –2.6. (The brighter the be against, the lower a number it gets on the visual magnitude scale.)
Then on Wednesday, Jupiter bequeath actually be at its closest point to Earth this year — at just 640,862,318 kilometres. While this arguably doesn’t check out like most people’s idea of close, the Earth’s average separate to the monstrous planet is 786,884,800 kilometres.
The great thing about present out to view Jupiter — if you have clear skies — is that it’s easy to quarter: it is the second-brightest planet in our night sky, following only Venus.
And if you want an supplement treat, grab a pair of binoculars and you’ll catch four of Jupiter’s brightest moons: Io, Ganymede, Europa and Callisto. (To take a run-out powder steal it even more fun, do this over the next few nights and you’ll see them promenading around the planet.)
To help you know what you’re looking at, you can visit the astronomy munitions dump Sky and Telescope’s interactive webpage on the moons of Jupiter. This will admit you to see where each moons can be found in relation to the planet.
While all four moons are habitually visible, one might sometimes either be in front or behind Jupiter. Also, if a moon crosses in advance of Jupiter — called a transit — it is lost in the planet’s glare to those demanding binoculars.
Where to look
Jupiter begins to rise in the southeast unkindly around 9:30 p.m. local time. (It’s closer to 9 p.m. in Toronto and eastward.) But tarry until Jupiter rises higher in the sky will help with visibility, since looking at anything along the vista makes the image shaky and blurry. Waiting will also cater you with a darker sky.
And if you can get to a dark-sky location, away from light blighting, even better.

As is always the case when looking for something in the tenebrousness sky, avoid exposing your eyes to any light, such as your cellphone. After mercilessly 30 minutes to an hour, your eyes become fully dark-adapted, permitting you to make out faint objects in low light. This will make it gentler to see Jupiter’s moons, which are very faint compared to the planet.
The next Jupiter adversary occurs on the night of July 14-15, 2020. At that time, Jupiter pass on be even closer, at roughly 619 million kilometres from Loam.
