An object that small probably wouldn't have any significant effect on the Sun at all (which is 800,000 miles in diameter, and made of gas, so it's not like the impact would do anything). Most objects would accelerate as they got closer, due to the Sun's gravitational attraction, but since this object is already moving at 16 times the speed of light (as Musashi pointed out), it's clear we can't be dealing with a real object. Since it's already violating one law of physics, who's to say whether it will obey others?

define pass through the sun
because anything near the center of the sun wouldn't last long. the high pressure there creates densities higher than any metal we know of. it would hit and stop or bounce off. if it stayed long enough it would succomb to fusion and not be the same object. if it passed through the sun but at an angle from the center, it would probably be deflected quite a bit. only thing I can think of that could pass through the sun is a neutrino. some would hypothesize gravitron, but that's not real to us.

Edited again to change "beta to ß" As yaohua has just pointed out (indirectly), our hypothetical object can get there in 27 seconds of it's time. gamma has to be 18.25 so sqrt(1-ß^2) has to be 1/18.25 (1-ß^2)=1/333.0625 so ß^2=332.0625/333.0625 and ß=.996998 That is, your object will be travelling at .996998 of the speed of light. from our point of view The sun has diameter roughly 4.6 light seconds. since we are working in the particles reference frame, (we can't switch half way, otherwise it was meaningless to say it travelled to the sun in 27 seconds. 6*ß=4.6 so ß=4.6/6=.7667 Travels through the sun with an average velocity of .7667c I would lay money that this is substantially faster than the speed of light in the sun, and your particle will emit masses of energy as cerenkov radiation.(maybe that's why it slows down). But the idea of something travelling through the sun (other than, as has been suggested, a neutrino or some other particle that's not fond of interacting- but if it's one of them, why does it slow down?) like this is just silly. PS sorry about the mess the maths is in. I don't know how to do math symbols in BBcode (or even if it can be done). If this is incomprehensible, say so and i will fix it (or try).

As Musashi and Grey have pointed out....absolutlely nothing can be observed going at those speeds. At the speed of light, the object would have some much energy and mass, it would blow the Sun to smithereens.
It might be worth stating the object would not be from our solar system. IIRC, no object has been found in our solar system which has come from outside our solar system. [Hopefully, I am wrong on this.]

JFYI about using symbols in posts:
this lists symbols you can use by just pressing ALT and the number: example hold ALT + press: 0-1-9-8 gives: Æ There are more symbols than the ones in that list: when dropping the leading zero, you get other symbols. Like ¬ ┤ ╦ ▓ Maybe someone could bother to create (or find) a complete list of all symbols we can use and their corrseponding alt code?

it's mostly in black and white, but we see blue/red/yellow stars.
There are some very long period comets (thousands of years) that have been witnessed. they travel beyond our solarsystem each orbit. I can say without any doubt in my mind that objects from other solar systems enter ours. Quote:

Comets from beyond the Oort cloud should have velocities higher than expected. I do not belive any have been found....yet. Quote:

I am using two reference frames here: the particle, and the solar system (and just to be lazy ignored any movement of for example, earth around sun) Working in the reference frame of the particle, t is the travel time of 27 seconds. If the velocity of the object is such that it has sufficient time dilation to make the journey in 27 seconds, it may as well be c in our reference frame (as far as calculating travel time that we observe). In our reference frame this gives us a velocity of c and a distance of 500c*s to be covered in 27 seconds (from the particle's reference frame). This means the particle must observe 27s while we observe 500s, i.e. it must experience y=500/27=18.52 relative to us. (not 18.25, which I would have noted earlier had I not been so lazy). Nicolas: thank you very much for the info. Tee hee hee. Now I can do this! ßßßßßßßßßßßßßßßßßßßßßßß I'll edit my earlier post to make it neater (replace beta with ß, etc) now.

I did think it looked funny. It's close enough, though. *Simplification of "one who simplifies frequently"
