The Planet Vulcan is the largest object in the Vulcanoid Belt, at about the mass of Pluto. It's composition is almost entirely of Iron, nicknaming it the 'anvil' of the solar system. Because of it's small size, and close proximity to the Sun (0.14 AU), it has an orbital period of 19 days, and 17 hours. The planet is also rather dark for a planetary body, so any observation of the planet was made even more difficult thanks to the planet's dark appearance. Thanks to this, the planet was only discovered by Le Verrier (the same astronomer who discovered Neptune), in 1860. The planet has been visited a few times by spacecraft, although it is difficult to get there.

Mars is discovered to have life on it's surface by the early 2000's, when a successful sample return had returned samples of microbes in the Martian soil. Further follow up missions have confirmed this is not because of contamination. Rover missions on mars in the late 2010's have proved the existence of fossilized plant and animal life on Mars, which is hypothesized to have gone through a mass extinction event in the early days of the solar system because of the planet's inability to sustain life and a proper atmosphere. The discovery of underground lakes on Mars through orbiting probes gives many the idea that animal life could still exist in those lakes, but as they are underneath the poles of Mars, discovery of that life will likely have to wait decades. Because of this discovery, scientists have taken prominent care of the samples to avoid any potential biohazards, and also have made careful sure to not contaminate Mars with Earth bacteria either.

The Rings of Ceres were discovered in the 1980's through occultation, as astronomers were measuring the planet's size, shape, and albedo. It is the only object in the asteroid belt classified as a planet, as no other object in the asteroid belt is gravitationally rounded by it's own gravity.

The Moon Rhea of Saturn, is the second largest moon of Saturn. Discovery of it's rings proved to be an impressive moment in scientific history, as no other moon has been observed in the solar system to have rings. It's rings orbit quite close in to the Moon, but the passing pair Explorer Probes (launched by France in 1984) had proven the existence of the rings by a flyby of the Moon, sending back unexpected images of the Moon's rings.

Titan was the first Moon of Saturn that was discovered, in 1655. It is about the mass of Mars (1/10th the mass of Earth), giving it the position of the largest Moon in the solar system, with Propserina (Minthe's largest Moon) as the second largest moon in the solar system, followed by Ganymede. after the Columbus Probe (also launched by France) arrived in orbit around Saturn in 2001, the probe had also managed to launch an orbiting satellite into Titan's orbit to study it's composition, proving that Titan had oceans of hydrocarbons on it's surface through scientific analysis. Titan's physical appearance from space is the same as it is OTL, a hazy moon. It's atmosphere is more or less the same as OTL. Awaiting discovery on Titan is unique coral-like lifeforms in it's oceans, and patches of simple Moss and Plant like organisms on it's surface.

The Planet Minthe orbits the Sun in a roughly circular orbit, but inclined by 17 degrees to the orbital plane of the planets. The closest the planet comes to the sun is 340 AU, and the furthest it is at 360 AU, making it's orbit somewhat eccentric. It is around 7.7 to 8.1 times as far away as the Kuiper Belt, rendering it having no gravitational impact on it. OTL objects such as Sedna will not exist in this system, due to the presence of Nemesis.

The planet is a superterran ice world with a confirmed ring system, with a mass of 6.3 times that of Earth. Despite it's large size, due to the distance from the sun, the planet has close to no atmosphere which makes any hypothetical landings quite challenging. It would take a spacecraft many decades to arrive, at the very least.

The planet has 5 confirmed Moons. Persephone, Hecae, Nox, Mors, and Prosperina. They are similar in size to Pluto, Eris, Ceres, Pluto, and Mars respectively, with large spaces between each orbits, meaning the 5 moons of Minthe do not enact tidal forces on each other. Only the moons Persephone and Hecate are close enough to Minthe to be tidally locked, while the rest are far enough away to have their own rotation rates. Because of the distance from Earth, the planet Minthe and it's Moons are known only by their size, mass, and orbital configurations.

Visual images of them are pixelated and blurry because of the distance, this may change in future decades with the advent of more advanced telescopes. Because of Minthe's distance form the sun, many astronomers have theorized that the planet could have the most moons of any planet in the solar system. Minor moons are not able to be observed around Minthe because of the distance, future telescopes and advances in technology will yield more results about this, while the rest is scientific theory.



Nemesis is an ultra-cool red dwarf star a planetary system of seven known planets. It has a mass about 10% of the Sun's, a radius slightly larger than the planet Jupiter, and a surface temperature of about 2,953.15 K (2,293 °C). This gives it a stellar classification of M7V.
