Various phenomenons can lead to that discovery. For example when a ship is approaching a harbour from afar and you are watching it from the port at first you notice the top of the ship then the stern and then finally the whole ship. It is possible only if the ship was sailing on a curved surface. Else the whole ship would have been visible from afar.
astroneomers were not shunned because of the geocentric model but the heliocentric model (with the sun in the middle of the universe). This was because religious leaders believed that god created the earth as the center of the universe and this idea was believed by nearly everybody.
Some astronomers from the early 1400s include Regiomontanus, Copernicus, and Purbach. These astronomers made significant contributions to the understanding of the cosmos and laid the foundation for future astronomical discoveries.
The concept that all planets revolve around Earth is known as the geocentric model. This idea was proposed by early astronomers before the heliocentric model, with Copernicus and Galileo helping to advance the understanding that Earth and other planets actually revolve around the Sun.
Early Astronomers did not even have the compass. The early astronomers believed that the world was flat or round in shape. In truth, all the ancient knowledge that was passed on to the astronomers were not in Human understanding. The building of Pyramids, the ancients scriptures and text that tells of the astronomical charts and calendars were handed down to them as gifts. These were knowledge given by the gods. But the question is. Are the gods who gave us these answers are truly GODS ? or were they merely extra-terrestial beings advanced in knowledge and technology ? Academicians will off course throw out this story due to our failure to comply to the facts or rationality of logic. But many things on Earth defies the very fabric of common beliefs on rationality and logic. For instance, can we prove the existence of gravity or see gravity ? We cant. But we know that it exist. So there is your proof that such things DO exist. We as humans have to just remain to have the faith that many questions will go unanswered.
Mars was found in 1534 BC by Egyptian Astronomers.

The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.

EARLY astronomers primarily used mathematics; that's why so many "early astronomers" are described as "mathematician and astronomer". Until the invention of the telescope in the early 1600's, there were no astronomical tools beyond the octant.

Juno was the third asteroid to be discovered by astronomers early in the 19th century.
They were both early observational astronomers. Some people believe that after Brahe's death, Kepler 'stole' his data and used it to develop Kepler's three laws of planetary motion.
The big limitation was a lack of telescopes.
Not all of them did. The ones who did believe in strictly circular motions were influenced by Aristotle, who may have been the wrong-est person who ever lived.
Ptolemy's theory of geocentrism, which placed Earth at the center of the universe, was helpful at the time as it provided a simple model to predict planetary positions. It helped early astronomers make sense of the movements of planets in the sky. However, it was eventually replaced by the heliocentric model proposed by Copernicus.
