March 13, 1781 –
Scottish astronomer Sir William Herschel discovered Uranus (which he named ‘Georgium Sidus,’ in honor of George III,) on this date, which he first mistook for a comet.
It is the first planet discovered with the aid of a telescope. Uranus is the seventh planet from the Sun and is named after the Greek god Uranus, who was a god of sky.
And so it goes
