Telescope

Actually, Galileo did not invented the telescope. But he did build his own, improved telescope. His was the 1st telescope strong enough to actually view the planets and stars in space.

The first telescope (called a spy glass) used one convex lens and one concave lens. Galileo perfected it by using two convex lenses.

Galileo also invented the Geometric compass which was use for calculations and for measurements

The pendulum clock was another invention Galileo worked on but it was invented by Christian Huggens

im not sure but i also think he invented the thermometer and barometer but u should search for it
