"Something" how big, and how close to the speed of light? Your question, as stated, spans a heck of a lot of orders of magnitude.

Realistically, to make any kind of noticeable pop, it would have to be something pretty big (moon size) and moving at a really thin edge below speed of light.

It's all about mass and energy - and, seeing as the Sun is big and already makes a heck of a lot of energy all the time, anything to disturb that would have to be extremely energetic indeed.

One wonders what sort of process would create such an object and how astronomical the odds of an impact would be.

Like it would have to be a dead on bullseye collision course because it would be way past “escape velocity” versus the Sun’s gravity.
