${\huge{\underline{\underline{\mathcal {\red{♡Answer♡}}}}}}$

Galileo built his own telescope made observations that made people believe in Copernicus's sun-centered solar system model called the heliocentric model. The observations include:

1. Jupiter has moons orbiting it.

In addition, Galileo saw the planet's moons were moving with it.

2.The Sun moves from east to west.

Galileo observed that the Sun has spots. The changing number(/appearance) of sunspots visible from Earth concludes that the Sun rotates on its own axis.

3.Planets appear to move backward.

He observed that planets were moving in retrograde direction, appearing to move westward.

4.Venus has phases similar to the moon's. This established that Venus is circling the Sun, not Earth. .
