The recent (22 February 2017 CE) NASA announcement about the new planets in the TRAPPIST-1 system means we'll have to do something with it. The code for the planetary system by TukuroRecommended Readings:Navigating in red dwarf planetary system
Red dwarf planets tend to orbit close in to the parent star. This make any traveling attempt energy-costly. Red dwarfs' tendency to flare can also damage any spacecrafts, or anything nearby unprotected. Without specially-made spacecrafts for red dwarf navigation, traveling even to nearby planets can be challenging, and dangerous. Luckily, advancement in technologies caused the development of spacecrafts with high delta-v that can withstand flares and radiations to be possible.

The recent (22 February 2017 CE) NASA announcement about the new planets in the TRAPPIST-1 system means we'll have to do something with it. Modding them right into the Sol System, of course. I think I'll complete modding this system before starting my main project. Stay tuned! We already have something like it, jupiter and its moons :-) Seriously tho, all of the Trappist-1 planets orbit closer to their sun than mercury does to sol. And the star itself is a supercool brown dwarf only a little bit larger than jupiter. The orbits of the planets are so correspondingly close together, you can easily see them from one planets surface, and they would look as large in the sky as the moon is in ours. Its basically the jupiter system, just in intersteller space

Anyways, I'll try to get this side-project done in less than one week.

Anyways, I'll try to get this side-project done in less than one week. Can't wait to see what you come up with. I understand the planets are all tidally locked, and the entire system is smaller than the distance between Sol and Mercury, with 3 "M class" planets. Interesting. Why it would make for a fascinating basis for a novel. Maybe a colony ship that sets "sail" and what they find there...

Well i don't think that that system can support habitable planet due to its extremely tight habitable zone when compare to sol. For me , a habitable planet must have a mass of ~1.5 earth or radius of ~1.15 earth , and it must need a sun like star. The standard of mass and radius came from a report about habitable planet , but i already forgot where i get it.

If they are tidaly locked they are not habitable, storms would wreack everything and it would go from hot on the day side to very cold on the night side.

Actually the recent research said tidally locked habitable planets can survive nearer to the star. UPDATE: I SUCK AT MODDING PLANETS

'Scientists have found a new solar system filled with planets that look like Earth and could support life... they sit within the “temperate zone” and are the right temperature to allow alien life to flourish... capable of having oceans... life could flourish... contain so many Earth-sized and rocky planets, of the kind... to contain aliens... evidence of life on the planets... surface temperatures which allow for liquid water... exciting future target in the search for life.' www.independent.co.uk/news/science/nasa-announcement-today-trappist-1-alien-life-solar-system-latest-live-exoplanet-a7593941.html

'Scientists have found a new solar system filled with planets that look like Earth and could support life, Nasa has announced. At least three of the seven planets represent the “holy grail for planet-hunting astronomers”, because they sit within the “temperate zone” and are the right temperature to allow alien life to flourish, the researchers have said. And they are capable of having oceans, again suggesting that life could flourish on them. No other star system has ever been found to contain so many Earth-sized and rocky planets, of the kind thought to be necessary to contain aliens. The researchers might soon be able to find evidence of life on the planets, they have said. British astronomer Dr Chris Copperwheat, from Liverpool John Moores University, who was part of the international team, said: “The discovery of multiple rocky planets with surface temperatures which allow for liquid water make this amazing system an exciting future target in the search for life."' www.independent.co.uk/news/science/nasa-announcement-today-trappist-1-alien-life-solar-system-latest-live-exoplanet-a7593941.htmlTo be honest... I don't think even single one of them would even have surface liquid water or even atmospheres... Anyways, the possibilities are interesting nonetheless.

Yep, life is pretty rare it seems. Which kind of makes the idea of life on earth being by random chance hard to believe. (jmho) PS (Was trying to shorten my post just as you replied. Oops my bad.) PS Maybe that is why we are here, to go out and seed the cold and dead universe with life. Humans have only been around some say 100,000 years or so. In universal terms that's nothing.

Actually I am thinking of starting a solar system worldbuilding project involving you. Would be interesting to see what can we come up with.

Is it too late to discover that Charon is a mass relay?

(jmho) We can't say whether or not life is rare, because we only really know about one solar system, and we haven't even checked out the other places in the system that could support life (Europa comes to mind). Intelligent life may be rare, but we don't know this either. One possibility is that intelligent life has a tendency to destroy itself, or to nuke itself back to dark ages. Another possibility is that intelligent life has a tendency to avoid contact with other intelligent life to prevent conflict.
