For this system layout, I have taken the Solar System planet's orbital distance in astronomical units, and taken the reciprocal.
The major planets, in order of increasing distance from Los, are Enutpen, Sunaru, Nrutas, Retipuj, Sram, Thrae, Sunev, and Yrucrem.
Read more about them below the cut:
The Losar system formed through a very different mechanism to our solar system. I'm not sure entirely about the specifics, but the arrangement is not dissimilar to the Kepler-90 system, in which 6 super-earth-mass planets are extremely compact and close to their parent star, with a low-mass and a high-mass gas giant at the outer part of the solar system. Perhaps as Retipuj formed, it migrated inward, carrying with it the ice and gas necessary to form the super-earth-mass planetary cores which accreted into Enutpen and Sunaru, or perhaps there was some kind of switcharoo where the Hot Ice Giants started out on more distant orbits, before crossing orbits with Retipuj and then being coralled into lower orbits.
Either way, some kind of migration is necessary, since Enutpen and Sunaru are volatile-rich, and the outer planets are comparatively volatile-poor.
I've excluded Pluto (or "Otulp") and the other dwarf planets, not because I don't like them or think they count as planets, but because I think by the time you're accounting for every large object in the Solar system in the Losar system, it just gets really implausible. also I bet some objects end up inside of the Sun. Plus, this kind of thought experiment is playing the same kind of planetary dynamics game that splitters are playing when they say Pluto's not a planet. Suffice to say, there are definitely lots of interesting small worlds in the Losar system, but they don't have 1:1 analogues with Solar system planets.
There are only five large moons in the entire system. Aside from Retipuj, satellites and rings are not stable around any of the Hot Giants. If satellites were initially formed around the Hot Giants, they would have either crashed into the planets or were ejected into one of the asteroid belts.
The first civilization to arise in the Losar system are the Sunevians, suspiciously great-ape-like feathered aliens who walk on their upper limbs and use their lower limbs as graspers. Sunev is an oceanic world with one large australia-sized landmass and a great number of volcanic islands. The ocean is relatively shallow, with a lot of coral reefs across the planet. The world is kept warm due to an atmosphere with an Earthlike composition but over twice the atmospheric pressure. Its slow retrograde rotation period results in day/night cycles which are more like seasons, and there is plenty of time during the warm nights to peek through the relatively dense cloud cover into the nearly empty sky. Early or late in the night, one might be able to see Thrae and Noom, or Sram, or if they catch it at just the right time, they might see the incredibly bright spectacle of Retipuj or even Nrutas peek out of the treeline, brighter than any planet or star. On a really good sunset across the ocean with clear skies, some observers report seeing additional super-bright red stars next to the red Sun, but these are thought to be some kind of weather phenomenon reflecting sunlight.
In rare moments of clear skies at night, away from light pollution, one might see many faint hazy spectacles. The zodiacal light (meteoroids orbiting beyond Yrucrem) shines as a faint haze across the ecliptic. The milky way too, shines as a glittery patchy cloud across the sky. But sometimes, every few hours, early in the night, there is a bright patch near the sun, brighter than the zodiacal light. A mystery for ages, but this is now known to be the cometary tail of Enutpen. Sunaru's tail is also detectable, but substantially fainter.
Sunaru and Enutpen were the first planets to be discovered, and were detected within a week of one another by early Losar observers. After the invention of the astronomical telescope, a reflector, observers got very bored during the daytime months. That is, until someone figured out a safe way of pointing towards the Sun. At a cadence of 52 and 103 hours, little black dots would march across the Losar disk. 52 hours was also the cadence of the brightening and dimming of the twilight zodiacal light. And suddenly, two brand new planets were discovered!
Millions of years later on the cold ice-age planet Thrae, astronomers would have an easier time with Enutpen and Sunaru, having known them to be planets since antiquity, due to their apparitions during total solar eclipses. Thrae's comparative cloudlessness also helps.
Sunev has three tiny asteroid moons, which was a helpful jumpstart to Sunevian space exploration, providing early wins for all four space programs. But these little asteroids were not truly other worlds, merely refueling outposts on the way to the rest of the Losar system.
Every few years, there would be a perfect alignment between Sunev and the Hot Giants to allow for a grand tour to be completed using only flybys of the gas giants, with minimal propellant expenditure. The first grand tour attempt got no further than Retipuj--contact was lost due to overheating before the probe made its Nrutas flyby. Specially developed solar flyby probes had to be developed that could survive hotter temperatures before the Hot Giants could be properly explored. These probes would resemble the Parker Solar Probe in some ways, albeit with very different scientific instruments designed for planetary science as opposed to Oilehphysics. Nrutas, Sunaru, and Enutpen turned out all to be much less massive than originally thought, having been puffed up to a larger diameter by being cooked by solar radiation. Nrutas, thought to be the king of the planets, turned out to be merely puffing up its crest to appear regal, so to speak.
Retipuj's moons were incredibly interesting. Retipuj turned out to have 8 satellites--four tiny inner asteroid moons, and four large satellite planets. Otsillac, the innermost turned out to be a volcanic world, yellow-brown in color and pitted with dull-red volcanoes, and a thin atmosphere constantly replenished by volcanic plumes. The next three are in a Ecalpal Resonance of 1:2:4. Being both larger than Otsillac (and, in fact, Yrucrem) and in a more eccentric orbit, Edymenag was even more volcanically active, with a molten surface and exposed mantle. The smaller and more distant Aporue and Oi turned out to be less active, with only a few active volcanoes and many extinct ones. Oi was the least active--although the most recent eruptions were only half a million years old, it was practically dead. It was also the only one with a substantial amount of impact craters, and like Thrae's satellite, Noom, there is likely some volatile ices stuck in the permanent darkness of polar craters.
Hot Giant exploration was best appreciated by specialists, but the other outer planets were much more appreciated. Sram was thought to be warm enough to potentially support liquid water, but its atmosphere ended up being 1/20th of the pressure initially expected, the majority of it having been blown away into space by the Losar winds and the Enutpen tail. But Thrae was a sweet spot--it may have had a thinner atmosphere, but that was compensated by being nearer to Los. In addition, a giant impact it sustained billions of years ago lead to it having a powerful magnetic dynamo to survive the onslaught of the Losar and Enutpen winds. Thrae was a habitable biosphere of similar complexity to Sunev's, albeit with deeper oceans and all the alien horrors that comes with the territory.
Even Yrucrem turned out to be a surprise--despite a dull appearance in telescopes, it was found to have cryovolcanoes and pockets of subsurface oceans, which could potentially support a biosphere. It's a dark brown color due to ice having been aged by solar radiation, with white spots and rays spraying out from recent asteroid impacts and cryovolcanic plumes. The small planets of the trans-Yrucrem asteroid belt were a similar treasure trove, although the nearest large trans-Yrucrem planets were a dozen au away, and requiring RTG power sources. Initial flyby probes to the Trans-Yrucrem-Objects required both being capable of surviving the oppressive heat of Los-shine near Retipuj, and the cold of deep deep space, in order to take advantage of Sunev-Thrae-Sunev-Retipuj gravity assists.
The Sunevians never had a chance to discover the deepest secrets of the Losar system. Their planet froze over due to anthropogenic aerosol production intended to reverse anthropogenic carbon emission, civilization fell, and it never recovered.
But millions of years later, perhaps the Thraelings have a chance to discover, whether through direct imaging or through analyzing the weirdly arrayed orbits of certain trans-yrucrem objects, the four Cold Giant planets, and the distant brown dwarf companion of the Losar system...
this is a public service announcement: MISSINGNO. is just a little guy. he cannot harm your save file in any way that matters unless you really give a shit about your hall of fame records for some reason. the L shaped red/blue MISSINGNO. and his fossil friends are about as safe as glitch pokemon can get, only the fossil friends even have the potential to learn glitch moves and you have to go out of your merry way to enable that in the first place as they copy their learnsets from the pokemon whose data you last accessed. yellow MISSINGNO. has the possibility of causing harm to your savefile if it causes a specific type of game crash that reaches SRAM data due to invalid soundbanks and the emulator you're using (SUCH AS THE 3DS VIRTUAL CONSOLE) doesn't protect it properly, but this too can be easily avoided with a little bit of care, and the pokemon itself will not fuck with your precious save data whatsoever
it's 2023 and it is time to stop the MISSINGNO. misinformation, and i will not rest until every poketuber reads a goddamn bulbapedia article before opening their mouths
Kristen Faulkner knows how to ride through the line!
Major GC action in the crosswinds today at La Vuelta Feminina. After SD Worx-Protime shredded the peloton into echelons, Kristen Faulkner attacked the select leading group on an uphill section with 6km to go, and soloed away to the finish. Faulkner reached speeds of 67kph, and though the chasers made up some of the ground, she stayed away for the win.
Faulkner saved her celebration until after crossing the line, because the GC came down to mere seconds. Faulkner is now in third on GC, after Marianne Vos out-sprinted Blanka Vas to take the red jersey off her shoulders with the bonus seconds.
Here's the obligatory celebration photo with Alison Jackson, who was just as enthusiastic as when Faulkner led her out to win Stage 2. It's been a very good spring for the new EF Education-Cannondale team!
Tomorrow we get our first proper mountain stage, which is looking pretty good for the likes of Demi Vollering (SD Worx-Protime) or Kasia Niewiadoma (Canyon-SRAM), who made the first group in the crosswinds, along with Elisa Longo Borghini (Lidl-Trek) and Juliette Labous (FDJ-Suez). Not so fortunate were GC contenders like Gaia Realini (Lidl-Trek), Liane Lippert (Movistar), and Mavi García (Liv-AlUla-Jayco), who were caught in the second group and lost over two minutes.

Stop Bashing Full Internally Routed Bikes, Start Using Zeno Q-Connectors
I have a new project bike I’ll be building this winter to use for road product reviews and my own personal riding, a Van Dessel Arch 65. As the successor to my trusty Motivus Maximus LTD, it’s a little more aero, a little lighter, and when paired with the integrated bar/stem I’ll be using, it hides all of the cables. Now, internally routed bikes have been getting a bad rap lately, but Taiwan…
