He counted 850 stars. (That is what my teacher said.)
The first catalog of stars is credited to the Greek astronomer Hipparchus, who compiled his observations in the 2nd century BCE. Hipparchus cataloged around 850 stars and classified them based on their brightness.
Both could be correct it depends on the situation. If you could count the stars how many so you think there are? Count the number of stars you can see out the window.
Hipparchus was best known for many things. One of them, he invented trigonometry.
Hipparchus was best known for star catalog..
Count yourself

More than you can count

Perhaps you mean the satellite Hipparcos. It measured the position of over 100,000 stars with high precision. It also measured the position of 2.5 million stars, with lower precision.
