JUPITER IS ENORMOUS. Here’s A Photo Reminder.

That gorgeous piece of insignificance being eaten up in the frame by Jupiter is Io. That moon is almost the same size as our own, and serves as a reminder of Jupiter’s enormity.


How big is Jupiter’s  moon Io? The most  volcanic body  in the Solar System, Io (usually pronounced “EYE-oh”) is 3,600 kilometers in diameter, about the size of planet Earth’s single large  natural satellite. Gliding  past Jupiter  at the turn of the millennium, the Cassini spacecraft captured this  awe inspiring view  of  active Io  with the  largest  gas giant as a backdrop, offering a stunning demonstration of the ruling planet’s  relative size. Although  in the above picture Io  appears to be located just in front of the swirling Jovian clouds,  Io  hurtles around its orbit once every 42 hours at a distance of 420,000 kilometers or so from the center  of Jupiter. That puts  Io  nearly 350,000 kilometers above  Jupiter’s cloud tops, roughly equivalent to the distance between  Earth and Moon. The  Cassini spacecraft  itself was about 10 million kilometers from Jupiter when recording the image data.

As well, another solid contribution by Cassini. Thing is paying dividends when it comes to stimulating my galactic g-spot.
