lengths of the semi-axes are both equal to the radius of the circle. The length of the semi-major axis a of an ellipse is related to the semi-minor axis's length... |
Ellipse (redirect from Semi-ellipse) described below, knowledge of the axes and the semi-axes is necessary (or equivalently: the foci and the semi-major axis). If this presumption is not... |

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... |
Mercury's aphelion but not within its perihelion. All have semi-major axes larger than Mercury's, and hence there are no known inner grazers. Mercury crossers... |
Centaur (small Solar System body) (redirect from Centaur (astronomy)) elements: The Minor Planet Center (MPC) defines centaurs as having a perihelion beyond the orbit of Jupiter (5.2 AU < q) and a semi-major axis less than... |
Moons of Jupiter (section Origin and evolution) groups, with semi-major axes between 19–22 million km (12–14 million mi), inclinations between 144–156°, and eccentricities between 0.09 and 0.25. Most... |
includes Psamathe and the group's namesake Neso. The moons of the Neso group have orbital elements that are clustered with semi-major axes between 46–51 million km... |
centaurs with semi-major axes smaller than Neptune. Both are double ring systems around 2060 Chiron and 10199 Chariklo, discovered in 1993–2011 and 2013 respectively... |
that follow similar orbits to Himalia at semi-major axes between 11–12 million km (6.8–7.5 million mi) and inclinations between 26–31°. With an estimated... |
Effects of Planet Nine on trans-Neptunian objects (category CS1 maint: date and year) large semi-major axes, beyond a 3:1 resonance with Planet Nine, most of these objects would be in anti-aligned orbits. At smaller semi-major axes the longitudes... |
Co-orbital configuration (section Trojan minor planets) objects are of similar masses and thus exert a non-negligible influence on each other. The objects can exchange semi-major axes or eccentricities when they... |
Titius–Bode law (section Origin and history) increase of semi-major axes as a function of planetary index) in all the exoplanetary systems; when making a blind histogram of orbital semi-major axes for all... |

Scattered disc (category Scattered disc and detached objects) scattered and detached regions. Gomes et al. define SDOs as having "highly eccentric orbits, perihelia beyond Neptune, and semi-major axes beyond the... |
Earth radius (section Radius and local conditions) nominal Earth radius is sometimes used as a unit of measurement in astronomy and geophysics, which is recommended by the International Astronomical Union... |
Sednoid (category CS1 maint: date and year) such as 2013 SY99 and 2021 RR205, which have perihelia beyond 50 AU and semi-major axes over 700 AU. Despite this, these objects are thought to not belong... |
90377 Sedna (redirect from Sedna (Astronomy)) both Eris and Gonggong are farther from the Sun, at 96 AU and 89 AU respectively, than Sedna at 84 AU, despite both of their semi-major axes being shorter... |
Kuiper belt (section Mass and size distribution) complete half an orbit for each of Neptune's) corresponds to semi-major axes of ~47.7 AU, and is sparsely populated. Its residents are sometimes referred... |
