Perhaps his ship just has a broken jump drive, so he's stranded in empty space somewhere? But if Titan really is just our own Titan, and that's the last place we saw him, then it seems like he's really quite nearby, on a cosmic scale, and it shouldn't be such a big deal; it should take about an hour for a message to reach Earth at lightspeed, and then Thor can just Bifrost over and grab him.
It's about 5 hours to Saturn, but the larger point stands - anything going on on Titan is something that people from Earth would be able to detect in near real-time. Also, if Titan was intended to be the moon of Saturn, they missed a massive opportunity for spectacle by not showing the Rings...
Pretty sure Titan was intended to be a planet of another solar system.
But, still, I'd assume an off-screen jump on the way to Titan.

That's not really a big deal but I do like my plot critical thingamajigs to be slightly better established if the conflict of the movie is going to be based on them.
* Let's take the Bifrost discussion. If it can take anyone anywhere, then the kind of instantaneous travel we are discussing was developed by Asgardians thousands of years ago. If it is limited to just nine realms (planets?), then it is a lot more like gates/jump points/whatever everyone else is using and there are apparently thousands of those around the universe. In either case, establishing what was so damn special about Mar Vell's invention shouldn't have taken more than a line or two, especially as it certainly wasn't a universal teleporter. /nitpick
Yeah, the world-building of interstellar travel in the MCU is a bit lacking - we know routine travel uses jumps, that jumps are limited in range/destination (since it took a ridiculous number to reach Ego), that you need to get to specific points in space in order to be able to jump, but we don't know anything about how jump points connect, what the network looks like, whether it's natural or artificial, how many places are "off the grid", or how it compares to a generic FTL drive (that travels through the space between places, rather than skipping the journey entirely).
As for the Bifrost, we have no idea how limited or otherwise its scope is - it definitely has access to the Nine Realms, doesn't have (intentional) access to Sakaar, and may or may not have access to any other specific location.
For that matter, just the interstellar space phones raise a whole bunch of questions, that only get worse if you start contemplating the physics. Ultimately, the answer to a lot of this is "movie writers don't care about physics" so digging into it gets into things not addressed onscreen very quickly...
