  1. Luria is a G1V type star, it is slightly brighter and hotter than our sun - at around 20% more luminosity than our sun. It is a slightly above-average star, with a rotational period of 30 days or so. The Lurian solar cycle is usually every 15 years.
  2.  
  3. Kulina - A hot and dry, dead core of a gas giant that veered too close for comfort. Over millions of years, the former gas giant left behind its former core, which is tidally locked and primarily made of iron and metals, not unlike our Mercury - but much larger, at about twice the mass of Earth. Kulina whips around Luria in slightly under a week.
  4.  
  5. Veneration - A Venusian world (it's in the name!) that orbits closer than our Mercury. This exposes it to added solar radiation, resulting in the planet being broiled alive in an ocean of sulfur dioxide and carbon dioxide. There will be no survivable landings here.
  6.  
  7. Viakor - An 8 Earth - mass oceanic planet, orbiting close into the star as well. The three planets exist in a stable and even resonance with one another, with it's two Lunar mass moons flanking it's orbit. From Val Roa, they are often seen with the naked eye at different positions as they orbit around Viakor in less than a week. It's thick atmosphere keeps the ocean in a supercritical state, giving it a Neptune like appearance.
  8.  
  9. There is an asteroid belt separating the inner and middle solar system, of which some larger asteroids reside that can be seen with the naked eye from Val Roa. The more keen observer will make out the small "Stars" that seem to move over the course of weeks, the asteroids.
  10.  
  11. Val Roa - The Earth like world of this system, with no large moon like ours. Instead, it's moons were captured from the asteroid belt. Has a mass roughly equal to that of Earth, and a 9 degree axial tilt. Instead of seasons being caused by the axial tilt, they are mostly caused by the planet's slightly eccentric orbit and felt all across the planet. It's thin and dark ring is an old moon that got too close!
  12.  
  13. Bracken - A small, 5 mile wide moon that orbits just above low Val Roan orbit that is usually seen in lower latitudes of the planet. In a few thousand years, it will break up and form a new ring over the planet.
  14.  
  15. Dilva - A pale, 350 mile wide moon that orbits in Val Roan geocentric orbit - making it only visible to roughly a half of the planet.
  16.  
  17. Ciderfall - The largest of the 4, being a 950 mile wide moon that is the dominant moon of the bunch. Still doesn't have much tidal influence on the other moons.
  18.  
  19. Wondermint - A small, bright 8 mile wide moon that orbits past the others as the most reflective minor moon.
  20.  
  21. Keep your eyes open, for there are over a dozen small moons! More are still being discovered!
  22.  
  23. Mesmir - Roughly 11 times the mass of Earth, this planet is an ice giant, with it's reflective yellow atmosphere being the brightest of all the planets seen from Val Roa. It has a system of small asteroidal moons that orbit it.
  24.  
  25. Orlo - A living world with a mainly nitrogen based atmosphere. Has intelligent life resembling that of Earth's avian lifeforms. It's also a captured planet, orbiting in a wide eccentric orbit around Mesmir. It's atmosphere is about 50% thicker than Earth's atmosphere, it is also much colder than Earth.
  26.  
  27. Presna - A Saturn sized green gas giant with a mass of roughly 90 Earths, it has a fairly plain green appearance to it that is only broken by a belt of white storms near it's north pole. It has a thin ring system that is not visible with the naked eye.
  28.  
  29. Enion, Lars, and Sorora are icey moons that are each roughly about half the mass of the moon with subsurface oceans that may contain life.
  30.  
  31. Laken is a large Venus sized ice moon with a thin atmosphere. It is the most likely to host life out of all the icey moons of Presna.
  32.  
  33. Verilo is another example of a captured planet - it being 1.5x the mass of Earth orbiting in a large inclined orbit around Presna. It's very similar to Saturn's moon Titan, with oceans of methane and ethane. It is also host to crystalline based lifeforms.
  34.  
  35. Neprit and Sarna are small planets that are each about the same mass of Earth's Moon, with each of them having minor systems of asteroidal moons. Sarna has a thin ring system over it's equator.
  36.  
  37. The outer asteroid belt contains a large amount of icey objects, there are a few objects in this zone that approach dwarf planet status - however they are not gravitationally rounded so they are not considered planets.
  38.  
  39. Norbello and Maximo are a binary pair of planets past the outer asteroid belt. Norbello is 3 times the mass of Earth while Maximo is half the mass of Earth, both of them have complex atmospheres and geology - and also host subsurface oceans, with a chance of having life.
  40.  
  41. Eridon is the last planet in the system, taking around 600 years to orbit around the star. It is twice the mass of Jupiter, making it a super-Jovian gas giant. Because of its distance from Luria, it is not visible from Val Roa. It is host to a large ring system and has the most moons of any planet.
  42.  
  43. Ulania and Vers are a pair of Io-like moons that orbit quite close within Eridon's orbit, making them heavily volcanic and geologically active.
  44.  
  45. Tak is a Europa like moon about the mass of Mercury, with reddish striations across it's surface that may indicate bacterial life.
  46.  
  47. Trino is a Mars mass ice moon, with an active surface that must have been resurfaced in the past few million years - indicated by its lack of craters.
  48.  
  49. Uvo is another Martian mass ice moon, however it is almost entirely featureless - which is something that baffles everyone who tries to study it.
  50.  
  51. Snowen is a 9 Earth mass ice giant that orbits a distant orbit around Eridon, as a captured planet - because of Eridon's distance from the star, it is able to have a massive influence sphere, with Snowen taking a dozen or so years to orbit Eridon. Snowen also has it's own system of minor moons.
