Wow:

Total number of operating satellites: 1,381 (includes launches through 12/31/15)[1]

Wasn't aware that the +15,000 satellites (loosely defined) currently orbiting the Earth (according to SATCAT) are mostly junk...

But one other really interesting thing I found once in this data was that a huge percentage of all earth orbiting satellites are debris from China's Fengyun 1C sat, which they blew up into currently over 5000 pieces to test a missile [2]. I just think it's funny that China did this, and now we have to track every single piece indefinitely. :)
