Erebos (Test Page)

Erebos is a planet in the Trans-Neptunian Region of the Sol System.

It was the last major planet to be discovered in the Sol System, being discovered in 2017 after an almost 2 year search to find it after several eccentric orbits of dwarf planets and astroids, including Sedna, were found to show evidence of it existing. Until 2021 it was nicknamed Planet Nine.

Properties
Erebos is slightly smaller than Neptune, being 12 times the mass of Earth and a radius of 20,223km, like the other ice giants, it is has a small layer of hydrogen and helium with a mixture of rock and ice further down, its temperature is -261°C.

History
The first theory for Erebos was released in January 2016 after several TNOs including sedna were discovered to have highly eliptical orbits and evidence on the Nice Model suggested that there was a third ice giant which was later ejected, so the search began for the ninth planet.

In 2017, it was finally discovered, and in 2021 it was named after the Roman God of Darkness, dropping its nickname Planet Nine. It wasn't until 2024 when Diana was discovered and named. In 2046, Voyager 3 passed the planet, discovering Apollo.

Moons
Erebos has 2 moons; Apollo and Diana, Diana is a large moon slightly bigger than Charon, discovered in 2026. and Apollo (Sometimes spelt Apoyo) is a much smaller moon, only just able to make a spheroid shape, discovered when Voyager 3 passed the planet in 2046.

Appearance
The appearance of Erebos is very dark, but if it was much closer to the sun, then you would see bands of mid blue with a splodge of brown at the bottom, there are also some grey and baige bands. Erebos has 2 rings which are slightly further out, they appear blue.
