Content:  difficulty of discovering and tracking these objects during much of the year. Based on earlier considerations, this hypothetical super-Earth-sized planet would have had a predicted mass of five to ten times that of the Earth, and an elongated orbit 400 to 800 times as far from the Sun as the Earth. The orbit estimation was refined in 2021, resulting in a somewhat smaller semimajor axis of 380 AU. This was shortly thereafter updated to 460 AU. Konstantin Batygin and Michael E. Brown suggested that Planet Nine could be the core of a giant planet that was ejected from its original orbit by Jupiter during the genesis of the Solar System. Others proposed that the planet was captured 
Title: Planet Nine
Content: semi-major axis a ≈ 700 AU (orbital period 7001.5=18,520 years) ; eccentricity e ≈ 0.6, (perihelion ≈ 280 AU, aphelion ≈ 1,120 AU) ; inclination i ≈ 30° to the ecliptic ; longitude of the ascending node Ω ≈ 100 °. ; argument of perihelion ω ≈ 140° and longitude of perihelion ϖ = 240 ° The clustering of the orbits of ETNOs and raising of their perihelia is reproduced in simulations that include Planet Nine. In simulations conducted by Batygin and Brown, swarms of scattered disk objects with semi-major axes up to 550 AU that began with random orientations were sculpted into roughly collinear and coplanar groups of spatially confined orbits by a massive distant planet in 
Title: Planet Nine
Content:  Planet Nine was initially hypothesized to follow an elliptical orbit around the Sun with an eccentricity of 0.2, and its semi-major axis was estimated to be 400 AU, roughly 13 to 26 times the distance from Neptune to the Sun. It would take the planet between 10,000 and 20,000 years to make one full orbit around the Sun, and its inclination to the ecliptic, the plane of the Earth's orbit, was projected to be 15 °. The aphelion, or farthest point from the Sun, would be in the general direction of the constellation of Taurus, whereas the perihelion, the nearest point to the Sun, would be in the general direction of the southerly areas of Serpens (Caput), Ophiuchus, and Libra. Brown thinks that if Planet Nine is confirmed to exist, a probe could reach it in as little as 20 years by using a powered slingshot trajectory around the Sun.
Title: Planet Nine
Content: semi-major axis of 400–500 AU; ; orbital eccentricity of 0.15–0.3; ; orbital inclination around 20°; ; mass of about 5 Earth masses. In February 2019, the total of ETNOs that fit the original hypothesis of having semi-major axis of over 250 AU had increased to 14 objects. The orbit parameters for Planet Nine favored by Batygin and Brown after an analysis using these objects were: 
Title: Planet Nine
Content:  The Planet Nine hypothesis includes a set of predictions about the mass and orbit of the planet. An alternative theory predicts a planet with different orbital parameters. Renu Malhotra, Kathryn Volk, and Xianyu Wang have proposed that the four detached objects with the longest orbital periods, those with perihelia beyond 40 AU and semi-major axes greater than 250 AU, are in n:1 or n:2 mean-motion resonances with a hypothetical planet. Two other objects with semi-major axes greater than 150 AU are also potentially in resonance with this planet. Their proposed planet could be on a lower eccentricity, low inclination orbit, with eccentricity e < 0.18 and inclination i ≈ 11°. The eccentricity is limited in this case by the requirement that close approaches of to the planet be avoided. If the ETNOs are in periodic orbits of the third kind, with their stability enhanced by the libration of their arguments of perihelion, the planet could be in a higher inclination orbit, with i ≈ 48°. Unlike Batygin and Brown, Malhotra, Volk and Wang do not specify that most of the distant detached objects would have orbits anti-aligned with the massive planet.
Title: Planet Nine
Content:  The planet is estimated to have 5 to 10 times the mass of Earth and a radius of 2 to 4 times Earth's. Brown thinks that if Planet Nine exists, its mass is sufficient to clear its orbit of large bodies in 4.5 billion years, the age of the Solar System, and that its gravity dominates the outer edge of the Solar System, which is sufficient to make it a planet by current definitions. Astronomer Jean-Luc Margot has also stated that Planet Nine satisfies his criteria and would qualify as a planet if and when it is detected.
Title: Planet Nine
Content: mass of 6.2 Earth masses; ; semi-major axis of 380 AU; ; perihelion of 300 AU; ; orbital inclination of 16°. In August 2021, Batygin and Brown reanalyzed the data related to ETNO observations while accounting for observational biases, they found that observations were more likely in some directions than others. They stated that the orbital clustering observed "remains significant at a 99.6% confidence level." Combining observational biases with numerical simulations, they predicted the characteristics of Planet Nine: 
Title: Prognoz 9
Content: Mass: 1060 kg ; Periapsis: 380 km ; Apoapsis: 720000 km ; Period: 38448.0 min (26.7 days) ; Inclination: 65.5°.  The spacecraft with highly eccentric orbit was spin stabilized with a period of 113 s. The spin axis pointed towards the Sun, and was repointed every few days.
Title: HD 7199
Content:  The High Accuracy Radial Velocity Planet Searcher (HARPS) in Chile found it to have a planet with a minimum of 0.29 times the mass of Jupiter – 92 times the mass of Earth – with an orbital period of 615 days. The planet HD 7199 b was named Hairu in 2019. Hairu represents unity in the Makhuwa language.
Title: HD 59686
Content:  In November 2003, a planet was announced orbiting the giant star. A doppler spectrometer was used to look for effects on the star caused by the gravitational tug of the orbiting planet. Using the amplitude from the radial velocity method, he calculated the planetary mass as 5.25 Jupiter masses and with period 303 days. However that mass is only a minimum because the inclination of the orbit is not known. Using the stellar mass and period, he calculated the semimajor axis as 0.911 astronomical units. He found that the shape of the stellar wobble is circular, implying that the planet has zero eccentricity.
