Ke'lar system

Ke'lar system or RS 8496-3149-8-7732467-517 is a star system composed of a dim white dwarf and a brown dwarf. This system is located 38,740 light years from Earth. The age of the system is 7.5 billion years.

## Interesting facts:

* All 7 planets have river beds and atmospheres.

* Apparently there are no gas giants in this system.

## The Stars

### Ke'lar I

Ke'lar I or RS 8496-3149-8-7732467-517 A - is a DQ7.9 class white dwarf with a huge visible accretion disk. The star's diameter is only 19187.37 km and its mass is 0.7448 M☉. The star's luminosity is 0.14172. And the
temperature is 6390 K. The accretion disk of the star is huge, its diameter is 1176901.88 km! The temperature of the accretion disk is a terrifying 4.5913•10⁶ K.

### Ke'lar II

Ke'lar II or RS 8496-3149-8-7732467-517 B - is a L2.7 V class brown dwarf. This star is ~30 million years older than Ke'lar I. Ke'lar II orbits a white dwarf. What's interesting is that this star is tidally locked. The star's diameter is 85109.51 km and its mass is 63.456 M♃. The star's luminosity is 7.2848•10⁻⁶. And the temperature is 1865 K.

## The Planets

Ke'lar system has 7 interesting planets, and 3 of them have complex terrestrial and marine multicellular life. It is still not clear whether there was ever intelligent life in this system. This is hinted at by the river beds of absolutely every planet - which means that in ancient times there was water on them. Perhaps these planets were terraformed billions of years ago? However, simply natural causes cannot be denied. This star system is probably very rare, because it has 3 lacustrine ferrias with complex life.

Flora is rare, but despite this, life is very diverse and unusual. Terrestrial animals are adapted to high temperatures. The Ke'lar I accretion disk is very clearly visible from the surface of Andoria. Life on Andoria appeared thanks to panspermia

### Kuopia

Kuopia or RS 8496-3149-8-7732467-517 2 is a temperate lacustrine ferria with life is in tidal looking. The diameter of the planet is 11154.21 km, and the mass is 0.70516 M⊕. ESI: 0.946. Gravity is 0.9202 g. The orbital period is 78 days. The planet's temperature is -1/5 °C (272-278 K). The atmospheric pressure is 4.66 atm, and the atmosphere consists of 53.8% O2, 41.5% N2, 3.5% CO2, 1.13% H2O. Kuopia has a stable climate and numerous blue bioluminescent forests. There are no more than 10 large lakes on the planet. The biosphere is very diverse, beautiful and complex. There are no active volcanoes.

### Banteria

Banteria or RS 8496-3149-8-7732467-517 3 is a cool lacustrine ferria with life. The diameter of the planet is 11730.58 km, and the mass is 1.1684 M⊕. ESI: 0.758. Gravity is 1.3785 g. The orbital period is 234 days. The planet's temperature is -53/-56 °C (220-217 K). The atmospheric pressure is 15.8 atm, and the atmosphere consists of 67% N2, 32.6% O2, 0.387% CO2. Bantenia is truly a unique planet. It has a single huge lake consisting of 95% CO2 and 5% SO2. If you look at the planet from orbit, it may seem like a desert. Most of Banteria is covered by deserts. Despite this, the biosphere is amazing. Researchers who visited the surface reported unusual animals. Their appearance is exotic, resembling something between organic and exotic life.

### Lotose

Lotose or RS 8496-3149-8-7732467-517 4 is a cold arid superferria. The diameter of the planet is 12962.47 km, and the mass is 2.2162 M⊕. ESI: 0.554. Gravity is 2.1414 g. The orbital period is 1.224 years. The planet's temperature is -107/-108 °C (166-165 K). The atmospheric pressure is 8.92 atm, and the atmosphere consists of 80.8% N2, 16.6% CO, 2.6% CO2. Despite the fact that Lotose has a diameter similar to Earth, this planet is 2 times heavier. Lotose in ancient times had lakes and even unicecullar life for a long time, but, unfortunately, life died out due to gradual cooling.

### Ke'tari

Ke'tari or RS 8496-3149-8-7732467-517 5 is a cold arid subferria. The diameter of the planet is 5105.67 km, and the mass is 0.055055 M⊕. ESI: 0.468. Gravity is 0.3429 g. The orbital period is 1.967 years. Ke'tari's orbit passes through the asteroid belt. The planet's temperature is -127/-141 °C (146-132 K). The atmospheric pressure is 2.86 atm, and the atmosphere consists of 87.7% CO, 12% N2, 0.294% CO2. Ke'tari has a beautiful pink atmosphere. There were rivers of water on the planet, but unfortunately frequent asteroid impacts evaporated all the water. Ke'tari still has traces of rivers and craters.

### Larano

Larano or RS 8496-3149-8-7732467-517 6 is a cold arid ferria. The diameter of the planet is 6611.93 km, and the mass is 0.24544 M⊕. ESI: 0.407. Gravity is 0.91152 g. The orbital period is 3.237 years. The planet's temperature is -151/-163 °C (122-110 K). The atmospheric pressure is 0.152 atm, and the atmosphere consists of 79.1% N2, 20.8% CO. Larano has an unusual surface topography; some scientists suggest that this planet was once oceanic or marine. It is also possible that a subglacial ocean remains beneath the surface.

### Daamila

Daamila or RS 8496-3149-8-7732467-517 7 is a frigid arid ferria. The diameter of the planet is 8386.17 km, and the mass is 0.44889 M⊕. ESI: 0.268. Gravity is 1.0363 g. The orbital period is 12.364 years. The planet's temperature is -196/-201 °C (77-72 K). The atmospheric pressure is 0.0276 atm, and the atmosphere consists of 73.3% N2, 26.7% CO. The most distant planet. Daamila is the only planet in the system that has a large moon. There are no clouds on the planet. Daamila has evidence of ancient rivers and ice deposits. But how did liquid water appear at such a distance from the star?
