Jupiter

Jupiter

Currently really well placed in Gemini, Jupiter manages a very respectable altitude of nearly 60° under dark sky conditions when due south; perfect to raise it above any low altitude atmospheric turbulence.

A telescope shows lots of detail, but there are also four bright ‘Galilean’ moons to look out for.

As these pass in between Jupiter and the Sun, they cast their shadows onto Jupiter’s disc.

These events are especially interesting around opposition because the shadows line up with the moons.

I = Io = innermost satellite
II = Europa
III = Ganimede
IV = Callisto = outermost satellite
