Neptune is the eighth planet from the sun and how that was postulated was through observations and calculations by French astronomer Urbain-Jean-Joseph Le Verrier, who was studying gravity-induced wobbles of Uranus, the planet closer to Earth than Neptune.

This gave him the general area to look for what might be another celestial body. But, remember, you can't do any of this without clear enough skies for a 19th-century telescope to be able to reach out from Earth’s surface, break through our many layers of atmosphere and peer deep into our night sky.

On Sept. 24, 1846, just 15 minutes after midnight, German astronomer Johann Gottfried Galle discovered the planet Neptune at the Berlin Observatory. The name of the planet is derived from the Roman God of the sea, due to its ocean-blue colour.

On today's podcast, Chris Mei talks about the discovery of Neptune and how its addition to the solar system gave us a more comprehensive understanding of Earth.
