Phi Pyravii System

The Phi Pyravii System (φ Pyv) is a system of planets, dwarf planets, minor planets, moons, and all objects that orbit Phi Pyravii.

## Star

#### Anzû

Pronunciation: /ˈɑːn.zuː/ AHN-zoo

Anzû, also known as Phi Pyravii, is a lone yellow dwarf star of spectral type G4V, 47 light-years away in Pyravis. It was relatively easy finding exoplanets around such a star, with four found that resembled Juvin, Chronox, Urus and Norex. Its age and metallicity resemble Algo's and Anzû was the first star confirmed to be an Algolar sibling. This confirmed that stellar siblings can have wildly different planetary systems as the Algo system has many more planets and the moons of those planets are much smaller than those around Anzû's planets. Host star of the Anqanites.

## Planets

#### Caladrius (Anzû I)

Pronunciation: /kə.ˈlæ.dɹi.əs/ kə-LA-dree-əs

A Juvin-sized planet 330 times more massive than Algodoo. Violent storms with winds of over 1200 km/h rage through its atmosphere. It is almost white coloured, reflecting over 95% of light back out to space. Thus, even from Anqa, it shines brightly near the horizon and can even be spotted in the day. Thirty-six moons orbit this planet along with a dusty ring system.

#### Phoenix (Anzû II)

Pronunciation: /ˈfiː.nɪks/ FEE-nihks

A pale yellow, gold and red gas giant 495 times more massive than Algodoo. The atmosphere contains white water ice clouds similar to those found on Algodoo. Despite its unassuming appearance, winds of 1700 km/h blow around this gas giant. Sixty moons orbit this planet along with an expansive ring system reminiscent of Chronox's. Unusually for a moon, the habitable moon Anqa and the Rojares-like moon Horus have their own sub-moons, Quqnus and Ra and Khonsu respectively. The planet shares its name with Hadion's binary partner and the red giant Beta Pyravii.

#### Turul (Anzû III)

Pronunciation: /ˈtʊ.ɹʊɫ/ TUU-ruul

A salmon-pink coloured ice giant 25 times more massive than Algodoo. Despite its unassuming appearance, winds of 850 km/h blow around this ice giant. The planet and its moons are tilted 79°, meaning that they rotate on their side. Twenty-four moons orbit this planet along with a rocky ring system.

#### Strix (Anzû IV)

Pronunciation: /ˈstɹɪks/ STRIHKS

An orange coloured ice giant 24 times more massive than Algodoo. Storms often rage across its turbulent atmosphere. Winds of 2500 km/h blow around this ice giant. Eighteen moons orbit this planet along with a rocky ring system.

#### Alkonost (Anzû V)

Pronunciation: /ˈæɫ.kə.nɒst/ AL-kə-nost

A turquoise coloured ice giant 10 times more massive than Algodoo. Storms often rage across its turbulent atmosphere. Winds of 420 km/h blow around this ice giant. Eight moons orbit this planet.

## Dwarf planets

#### Huginn

Pronunciation: /ˈhjuːgɪn/ HYOO-ghihn

An icy dwarf planet. Huginn is 0.35% of the mass of Algodoo. They orbit on an eccentric and inclined orbit that crosses into Strix's orbit. Muninn, its binary companion, is about 80% the mass of Huginn and is so large that the two dwarf planets orbit around a point outside Huginn. Both Huginn and Muninn have thin atmospheres. Six moons, including Muninn itself, orbit this icy dwarf planet. Muninn has a moon of its own.

#### Ægialeus

Pronunciation: /ˈæ.d͡ʒɑː.li.əs/ a-JAH-lee-əs

A rapidly-rotating, blue-coloured icy dwarf planet with a ring. Ægialeus is in a 12:7 resonance with Strix.

#### Olocitad

Pronunciation: /əʊ.ˈləʊ.θɪ.tɑːð/ oh-LOH-thih-tadh

A grey-coloured icy dwarf planet. Olocitad is in a 13:7 resonance with Strix.

#### Azrien

Pronunciation: /ˈæz.ɹi.ən/ AZ-ree-ən

An icy dwarf planet with a large moon Lazo on a highly eccentric and inclined orbit.

#### Partran

Pronunciation: /ˈpɑː.tɹæn/ PAR-tran

An icy dwarf planet with a ring on a highly eccentric orbit that is strongly affected by the presence of Alkonost.
