While we're at it, here's the Rosetta comet, which will be at perihelion next month. And here's MMS. All 4 MMS's have a roughly 24 hr. orbital period. If you want things in near earth orbit, you can try to track them with J-track. I say "try", because I can't get it to work, it's been a java debacle. The promised update in 2012 was most likely never delivered.
