History
Discovery
-
The 1.2-meter Samuel Oschin telescope that was used to discover 2007 OC10 at Palomar Observatory on July 22, 2007
2007 OC10 was discovered on July 22, 2007, by Meg Schwamb and Michael E. Brown of the California Institute of Technology using the 1.2-meter Samuel Oschin telescope at the Palomar Observatory in California. The discovery was announced on September 6, 2007,[4] and confirmed in 2008 by the 1.5-meter Cassegrain telescope, also at the Palomar Observatory;[5]
Numbering and naming
2007 OC10 was later assigned the minor planet number 470316 by the IAU .[6] As of 2026, 2007 OC10 has not been officially given any name by the International Astronomical Union.[1]
Observations
Past observations
The observation arc of 2007 OC10 begins with the official discovery observation on July 22, 2007. Since then, 2007 OC10 has been observed by various telescopes, including the Herschel Space Observatory and ground-based telescopes.
As of April 2026, a total of 431 observations had been recorded over a period of 18.39 years.[2] The most recent observation was made in December 10, 2025 at the F51 – Pan-STARRS 1, Haleakala.[2][1]
Future observations
2007 OC10 has not been imaged by high-resolution telescopes yet, so it does not have any known natural satellites or moons,[7] which means there is currently no way to measure its mass and density.[8]:1,3
Orbit and classification
Orbital characteristics
2007 OC10 is a trans-Neptunian object orbiting the Sun at a semi-major axis or average orbital distance of approximately 49.6 astronomical units.[1] It follows a highly tilted and elliptical orbit with an eccentricity of 0.285 and inclination of 21.67° with respect to the ecliptic.[1] During its 350-year orbital period, 2007 OC10 comes within 35.5 AU from the Sun at perihelion and up to 63.8 AU at aphelion.[1]
Classification
2007 OC10 belongs to the scattered disc,[9] which is a population of TNOs that have distant, inclined, and eccentric orbits that come close to Neptune at perihelion.
The scattered disc population, which includes the dwarf planets Eris and Gonggong, are strongly influenced by Neptune's gravitational perturbations and consequently experience gravitational scattering.[10]:52
2007 OC10 is classified as a scattered disc object by Johnston's archive.[9]
