I even looked it up and still can't give a coherent definition. Something something fixed positions astronomy something. Yeah. That's it.
It is pronounced sidereal.
Had to make the joke since no one else did.
I think side ear eal, those parts have 1, 1, and 2 syllables respectively. Long e, short a on the last 2 syllables. That should get you close.
Oddly, can't remember what it means as I type this even though I remember the pronunciation.

Like actually fixed positions? If you think anything in astronomy has a fixed position you're an idiot. I'm not attacking you there just making a note for if I ever hear someone use that word seriously.
Any answer I give will be wrong because I didn't understand the definition. I think it was fixed in relation to the horizon at a certain time of year, but as to why, idk. Ugh, I don't want to go figure it out...
