Jupiter's Temporary Moons

Sarah Zielinski writes in The Smithsonian that Jupiter, as the largest planet in our solar system, occasionally pulls comets into its orbit. Sometimes, as with comet Shoemaker-Levy 9 in 1994 (pictured), Jupiter's gravity will even pull a comet into a direct impact. Zielinsky writes:

Astronomers from Japan and Northern Ireland, presenting their findings today at the European Planetary Science Congress, used observations of Comet Kushida-Muramatsu—from when it was discovered in 1993 and when it returned in 2001—to calculate the comet’s path over the previous century. They determined that the comet became a temporary moon when it entered Jupiter’s neighborhood in 1949. It made two full, if irregular, orbits around the planet, and then continued its travels into the inner solar system in 1962.

The researchers also predict that Comet 111P/Helin-Roman-Crockett, which circled Jupiter between 1967 and 1985, will again become a temporary moon and complete six loops around the planet between 2068 and 2086.

“The results of our study suggests that impacts on Jupiter and temporary satellite capture events may happen more frequently than we previously expected,” David Asher of Northern Ireland’s Armagh Observatory told the AFP.

Outstanding! I can't find any explanation at the link regarding why this process wasn't commercially exploited. Perhaps audiences were sufficiently awed by B&W, and this would have been more expensive.

Thanks for posting this.

Anyone up on their old silent movie actresses? I thought the last woman looked a lot like Mae Murray, but wasn't sure. Hopefully, I am not the only one left out there who knows who Mae Murray was!

Wow Marty you're good! My only reaction to her was hey she somehow looks familiar, but then again lots of these actrices from back then have a certain kind of stereotype look. Just like nowadays they all would look the same if we would look back at them about a hundred years later.

To see her in moving color is amazing- never thought to see that.
