View Full Version : Discussion: Audio: Sedna Loses Its Moon

SUMMARY: Remember Sedna? It's that icy object uncovered last year in the outer reaches of the Solar System. When it was first discovered, astronomers noticed it rotated once every 20 days. The only explanation that could explain this slow rotation was a moon, but a moon never showed up in any of their observations. Scott Gaudi is a researcher with the Harvard Smithsonian Centre for Astrophysics. He and his colleagues have been watching the rotation of Sedna with a skeptical eye, and think it's only rotating once every 10 hours or so. As for the moon? Easy come, easy go.

I couldn't get the audio to open, but the podcast is a wonderful idea.

It should just be a regular mp3 file. You right-click on the file and then save it to your desktop. You can play it from there.

Very nice addition to the site!

This makes a whole lot more sense than what had been concluded earlier. It also makes Pluto much more interesting in my mind. I would not have expected a KBO-sized object to have a moon, especially one as large a proportion of its size as Charon.
