I mean, couldn't it be a geostationary orbit?
I
could be, but it
is not. A geostationary orbit requires a specific distance from the Earth’s centre (42.164 Mm, which translates to 35786 km above the mean equatorial surface). Also, it would have to be over the equator, and when I checked yesterday, Titan was roughly over the vicinity of the Caspian Sea. (Also it appeared to be stationary with respect to Earth’s centre, with Earth slowly rotating below it.)
Well, most of the mass doesn't go into the explosion itself but is instead annihilated by it.
That would be true only if it were an animatter–matter explosion… if it were anything else, the mass would not be annihilated but dispersed, with some parts of it likely hitting Earth’s atmosphere, where any macroscopic chunks would heat up and burn spectacularly, and bigger ones would make it to the ground. Depending on the total amount of mass and energy ending up in Earth’s atmosphere, this might or might not be a major extinction event.
BTW, above certain threshold the total mass and energy are more important than how big the pieces are. Phil Plait a.k.a. The Bad Astronomer once wrote a review of
Deep Impact, where he explained why blowing up a large asteroid (or comet) about to hit Earth is potentially a worse idea than just letting it hit undisturbed.
*I saw somebody mention Sol going nova as a possibility of the Titan's actions but would the stellar forge permit that?
I’m sure it would not. (Also it would be far sillier than anything we’ve seen in ED thus far.)
(Also, this post already is using the word
also too many times.
