MB466LL/A and Mavericks?

Hello. I've got a MacBook, purchased new from Best Buy in June 2009. I was running 10.5.8 until today (hard to believe, I know), successfully upgraded to 10.6.8 without any problems. My system specs are posted below (though removed the serial number and parts of the Hardware UUID). My question(s) are: Can this system support Mavericks? I've looked at Yosemite and it's essentially just iOS for MacBooks - Not appealing.

If Mavericks *isn't* supported, which is the newest version of OSX that this computer will support?

I've still got the original box, the stickers on it say the Model number is: A1278

Any help would be appreciated, thanks much in advance
