ANU by Sanrou ANU by Sanrou

ANU is a small and rocky planet with 21% of Earth's gravity and only 0.17° in axial tilt.

The second fact gives the planet some peculiar characteristics: during the day, the solar winds strikes in the middle of the planet and despite the excess of heat and radiation, a green and lively ecosystem can be seen on the axis of rotation (Abzu Belt). That happens because when the solar winds hits the planet, it goes in direction of the icy poles, cooling and descending on the dusk line of ANU. This happens in both hemispheres, and when the two cold air masses meet each other, with the hot exo-equatorial air, they cause a never-ending rain across the middle of the planet on its night side, providing a less inhospitable place for life to emerge.

There are no seasons, no brake from the monotony that it is the simplistic and stable weather that exists for millions of years. The Tiamat Mountains (average of 7.4 Km; Maximum of 11.2 Km) slows the heat and the solar winds enough to allow a greener and humid place for life to evolve, consisting of the Eden Valley, Lake Maria and Lake Sagan.

The lifeforms will be added soon.

Sorry for murdering the english language (corrections are welcome) Sweating a little...

TO have a magnetic field, it must still have a molten core. What's the rest of its' tectonic situation like?  Also, what's the day length?

I had imagined as a in the last moments of the active molten core (about a 100 million years left), and as such, with a minimal to none movement of the tectonic plates. The days are about 36 to 37 hours long  :)

And once the core freezes, the solar wind won't just influence the atmosphere, but strip it away entirely. Hopefully some intelligent species will evolve before then and take precautions...

And speaking of the atmosphere, it probably has a lot more hydrogen and helium than such a small planet normally would, because of that solar wind.

Mundo interessante. Por ser velho e ter baixa gravidade esse mundo não teria perdido sua atmosfera por causa do vento solar? Ele não tem massa pra ser ativo geologicamente e ter um campo magnético forte com a idade que possui. A menos que a vida do planeta reponha a atmosfera constantemente.

Obrigado! De fato, baixa gravidade e a ausência de um campo magnético significativo implicariam fortemente em um planeta estéril e sem atmosfera, mas é aí que entra a história geológica do planeta: ANU é um planeta distante de sua estrela, existe praticamente "fora" da zona habitável de seu sistema solar, e pela maior parte de sua existência era uma bola de gelo com 3 vezes mais massa cuja vida provavelmente já existia em lagos sob o gelo aquecidos e alimentados por chaminés vulcânicas. Em algum período 1 bilhão  de anos atrás, um planetoide com mais de um terço do seu tamanho se chocou com ANU, jogando grande parte de seu gelo para a órbita exterior e remodelando o planeta. Nos séculos subsequentes ao impacto e remodelamento, ANU era coberto por um oceano raso onde a vida (que já existia e "choveu" de volta ao planeta dos pedaços de gelo que o cercavam) explodiu e se multiplicou. A partir desse ponto, por mais alguns milhares de anos, o gelo orbital voltava ao planeta e as formas de vida nele ajudavam a equilibrar a atmosfera e suas trocas de gases em um constante efeito-estufa. O fato de ser longe de sua estrela, somado a sorte, fez com que a degradação da atmosfera por ventos solares fosse mínima. Só que esse equilíbrio não duraria para sempre: No período representado nesse projeto ANU está começando um resfriamento. Sua atmosfera está se perdendo mais rapidamente e de aproximadamente 50 a 70 milhões de anos ANU se tornará uma bolinha de gelo novamente   :)

Estava escrevendo toda descrição de um dos meus planetas por o seu ter lembrado um pouco o meu mas o pc bugou e perdi tudo (Meu Da é foca do em Dragon Ball então prefiro deixar isso apenas pra mim mesmo XD) . Minha bolinha densa de Ferro chamada Elari. Bom se você quiser saber sobre ele eu escrevo tudo novamente. De qualquer forma as imagens que ia mandar. XD

Elari Isso me lembra que é uma boa melhorar o mapa.
Elari Elari 2 Elari 4 Elari 5 um dos motivos de amar usar o celestia. XD
Aliens De Um Planeta Com Gravidade Baixa Comecei tudo por causa dessa arte e usurpei algumas coisas dela. :V 

Teria a textura de Anu sem as marcações e tal? Posso fazer um adon no celestia com ela bem de boa. xD

How old is this planet? How long since it developed life? It has always been this dry?  Do humans live there? Can we eat the lifeforms and get nutrition from their tissues? How far is it from the Solar System? 

Reminds me a little of Nea, from a (seemingly) discontinued project by Joschua Knüppe.

It's difficult to say, but about 5 billion years;
Estimated in 3 billion years, with a evolutionary explosion of diversity after a major impact had transformed Anu from a snowball into a greenhouse desert;
yes and no. Not humans in the sense that we are now;
Yes, but the human basic need for food is absent for the colonists.
It's located somewhere in Andromeda.

While the work of Joschua inspired me greatly, his Nea project was not on the list, but I can see the similarities. His work on Silvanus, for example, was the major push for me to start my own xenobiological project.

The Darwin's Forest, and the Wallace's Forest are at the poles, above and below the glacial ice? How does this work? It sounds really awesome!
Also this project is one of my favourite speculative exobiology projects out there, I love the detail and how unique all your creations are

Most of the polar forests usually don't make direct contact with the ice caps themselves, but there are some sturdy organisms that have colonized above the ice. ^^

So the Twilight Storms appear on the borders of the transitional, "day" and "dark" sides of the planet?

Yes. Twilight always brings a storm, then followed by a heavy but calm rain, all the way to morning. It have been this way every day for millions of years.   ^^

My dear fellow, I am really interested in exploring your concepts and art so I decided to start with the map of this planet you've created, yet I can't get the full-res. version from the download link (says 404).

Any chance that's fixable, or is it just a problem on my side..?

Edit: Ah, nvmnd, the link works now. I really like how you've bothered to actually create the environment/world for reference for the fauna in your art. Great!

I've always wondered, does ANU mean anything? Is it just one word, or is it an acronym? Also, when's your next piece coming out? I love your work

Oh, thank you! :D
Anu is a sumerian deity, one of the two mythology's that I used to name geographic locations on the planet (the other being christianity).

I try to upload my work as quick as I can, unfortunatly I don't have many time in the week to dedicate to this project of mine. Sweating a little... 

And thank you very much for the watch and faves!
