Recently, scientists have discovered a planetary system with three suns. This quite fascinating, because it makes you wonder, how would the planet orbit all three suns? In our system the Earth goes in a circle around the Sun.

Hi Joey,

Thanks for the report! :)

The first tentative sighting I know of to have been reported was Konacki's (tentative) Planet, reported in Nature, in 2005. [http://www.nature.com...] [http://www.jpl.nasa.gov...], but later observations suggested it wasn't there.

However, I note that NASA has this year reported another, further away, and this may be the one you mean. [https://exoplanets.nasa.gov...][http://science.sciencemag.org...] This seems to have been reported with direct imaging, which would make it a confirmed sighting: they're now analysing atmosphere for water, which is hard to do on a planet you can't see. :D

This quite fascinating, because it makes you wonder, how would the planet orbit all three suns? In our system the Earth goes in a circle around the Sun.

At the time of reporting they were still working out possible orbits, but have conjectured that the planet orbits the primary sun, while two stars also orbit the primary sun while orbiting each other -- like a dumbell spinning on the end of a swinging string. Please see the European Southern Observatory video, linked right.

Also fascinating is how a planet might form under these conditions. Apparently, there aren't many places in a trinary system they can form.

It is more common for a solar system to have multiple suns than to have just one like ours.

That is in fact true. It's funny how it seems, because we think one star systems are common because we live in one.

Yes i was a little surprized to find that out. It seems that double star systems are a lot more common than triple or more, as they have more stable orbits. Than ks for having an interesting topic to look into today.

You're welcome. I also find this topic quite intriguing.
