Sona wrote: “Tremendous blissful to have seen the uncommon occasion of a triple shadow transit on Jupiter, although I missed Callisto’s shadow transit (the homes impede my views). Io sprung a shock entry into the body and for a really temporary second solid its shadow!” Thanks, Sona!

Jupiter at perihelion in 2023

Jupiter’s last opposition – when Earth in its orbit flew between Jupiter and the sun, inserting the enormous planet reverse the sun in our sky – occurred on September 26, 2022. Then Jupiter was nearer to Earth than it had been in 70 years. And now comes the rationale for that shut method of Jupiter to Earth final September. That’s, Jupiter’s perihelion or closest level to the sun comes right this moment – January 20, 2023 – at 12 UTC.

That is Jupiter’s closest level to the sun in its practically 12-year orbit. The space between the sun and Jupiter is now 460 million miles (740 million km).

And it was the shut conjunction in time between Jupiter’s yearly opposition – and its once-in-12-years perihelion – that gave us the shut method of Jupiter in September, 2022.

Available now! 2023 EarthSky lunar calendar. A unique and beautiful poster-sized calendar showing phases of the moon every night of the year! Makes a great gift.

A more in-depth take a look at orbits

Earth and Jupiter go across the sun on virtually the identical aircraft. Jupiter’s orbit takes 11.9 Earth-years. And Earth’s orbit takes one yr.

Each Earth and Jupiter have orbits which are very practically round. If the orbits have been precisely round, with the sun within the heart of the circle, each Earth and Jupiter would at all times keep at the very same distance from the sun.

However the orbits of each Earth and Jupiter are very barely elliptical, (like a squashed circle). So Jupiter’s distance from the sun varies, and it has a nearest level to the sun and – half a dozen Earth-years later – a farthest level from the sun.

Earth’s perihelion – or closest level to the sun – happens yearly round January 4. We’re farthest from the sun yearly in early July.

Jupiter perihelion doesn’t occur so commonly, with respect to our earthly calendar. It falls on completely different dates throughout an earthly yr, each 12 years.

Jupiter final handed aphelion – its farthest level from the sun – on February 18, 2017. Jupiter’s subsequent aphelion will are available 2028.

Since 2017, Jupiter has been transferring nearer to the sun – little by little, nearer and nearer – each earthly day.

Now comes its closest level to the sun, right this moment.

This animation reveals an orbit that’s vastly extra elliptical than both Earth’s or Jupiter’s. Nonetheless, you get the thought. Perihelion = closest to sun. Aphelion = farthest from sun. Picture by way of Brandir/ Wikimedia Commons.
