The god of the seas and the messenger of the seas visit the water carrier

Neptune, the eighth planet from the Sun, is shown here in the middle of this image with the moon Triton just below it and to the left.  This is a one second exposure and North is down and to the left.

Taken at 8:40 pm on October 30, 2016 with the Prompt 3 telescope in Chile,  the image shows the moon just 13.93 arc seconds from the planet.

Triton orbits Neptune at a distance of about 354, 800 km.  That’s a little closer than our Moon from the Earth (384,400 km)

Triton is about 80% the diameter of our moon.  It orbits Neptune once every 5.877 days.

Neptune is one of two giant ice planets in our solar system.  It’s about 17.1 times the mass of the Earth and presently about 29.42 AU from the us.

The planet Neptune is named after the Greek god of the sea.  Triton is the largest of 14 known moons of Neptune, and is named after the messenger of the sea.

On October 30, 2016, when  I captured this image, the planet and moon were in the constellation Aquarius, named after the water carrier.
