Easy enough to find out.
Take a pic or do a drawing of the locations of the supposed moons. Then wait 15 minutes and do it again. Then again another 15 minutes later. You should notice a change in orbit of the moons in this time. If not, give it another 1 or 2 goes at 15 mins apart and compare with the first one. No orbital change? It's a star. Orbital change? It's a moon.
