Dathn

Located 2.59 million light years away in the Andromeda galaxy, Dathn (also categorized as CoSSiAG 1) is a M-type star in a binary system with a brown dwarf nicknamed Dusky. They both orbit each other around a mathematical point called the barycenter, which is the point around which two or more bodies revolve around one another as well as the center of mass of those bodies.
Dathn has a mass of about 0.094515 solar masses (99.01125 Jupiter masses) with a diameter about 139981.12 km (0.1006 Solar diameter) and a solar luminosity of about 0.00020776. It has a density about 130.86 g/cm³ and had a stellar age of about 100,000 years, meaning when the Dathn was being formed by a stellar cloud of gas, Homo sapiens on Earth still lived in caves, huts, or tepees and were still hunters and gatherers. They used basic stone and bone tools, as well as crude stone axes, for hunting birds and wild animals.

Dathn α is a disproved exoplanet orbiting Dathn. If it existed, the semi-major axis would be 1407666 kilometers (0.00941 astronomical unit), meaning it would be smaller than Trappist-1 b and almost the distance of the geosynchronous orbit of Dathn, making scientists skeptical the exoplanet is really real or it was just an abnormally large sunspot. It is calculated that Dathn α has a mass of about 1.2 Earth masses and a radius of 1.4. It was discovered by the transit method, which is when a celestial object passes directly in front of another, bigger body. The transiting body seems to travel over the face of the bigger body while the observer views from a certain vantage point, usually only covering a tiny area of it depending on the distance of the observer. Even while the fake exoplanet—which turned out to be a sunspot that mimics the exoplanet transit—started to decay after a while, there are now no longer any signs of it left.
