Galileo di Vincenzo Bonaiuti de’ Galilei
(15 February 1564 – 8 January 1642)

With eight planets in our solar system, more than 200 moons
surround those natural satellites.

Jupiter, one of the most recognizable planets, has 80 of those
moons.

On this day in history, Jan. 7, 1610, Galileo discovered the
moons of Jupiter — making it the first observation of this
planet. 

The astronomer discovered the moons with a homemade
telescope.
