NEPTUNE, THE FINAL PLANET?
Today is the 175th anniversary of the discovery of Neptune, the eighth and furthest planet in our solar system from our sun. (Some of us are still mad about Pluto’s demotion.)
But back to Neptune, it is the only planet not visible to the naked eye. It was predicted by mathematics before it was actually discovered.
Neptune takes 165 earth years to orbit the sun and a Neptunian day is about 16 hours long.
The giant ice planet has 14 known moons and faint rings made up of dust and debris.
Janus and Oceanus were originally proposed as names for the planet, along with Le Verrier which would have named it after the man credited with the discovery. But preference for a mythological name was proposed by the scientific community, and Neptune was quickly agreed upon.
This superb celestial chart of the northern and southern skies is by Seutter, issued in 1730.
