In the Solar System, many of the asteroid-sized moons have retrograde orbits, whereas all the large moons except Triton (the largest of Neptune's moons) have prograde orbits. [13] The particles in Saturn's Phoebe ring are thought to have a retrograde orbit because they originate from the irregular moon Phoebe.
S/2004 S 24 is about 3 kilometres in diameter, and orbits Saturn at an average distance of 22.901 Gm in 1294.25 days, at an inclination of 35.5° to the ecliptic, in a prograde direction and with an eccentricity of 0.085. [1] Due to its inclination being similar to members of the Gallic group, S/2004 S 24 could belong to the Gallic group. [4]
Transatmospheric orbit (TAO): geocentric orbits with an apogee above 100 km and perigee that intersects with the defined atmosphere. [4] Very low Earth orbit (VLEO) is defined as altitudes between approximately 100 - 450 km above Earth’s surface. [5] [6] Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (1,200 mi). [7]
An inclination of 0° means the orbiting body has a prograde orbit in the planet's equatorial plane. An inclination greater than 0° and less than 90° also describes a prograde orbit. An inclination of 63.4° is often called a critical inclination, when describing artificial satellites orbiting the Earth, because they have zero apogee drift. [3]
Apparent path of S/2019 S 1 as seen from Earth during 2019–2021. Coloured circles along the path mark the dates and locations at which the moon was observed. S/2019 S 1 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 11.2 million km (7.0 million mi) in 443.78 days, at an inclination of 44° to the ecliptic, in a ...
The prograde satellites consist of the Himalia group and three others in groups of one. The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups. Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small.
The inclination and semi-major axis are represented on the Y and X-axis, respectively. The satellites with inclinations below 90° are prograde, those above 90° are retrograde. The X-axis is labeled in terms of Saturn's Hill radius. The Gallic group is a dynamical grouping of the prograde irregular satellites of Saturn following similar orbits.
S/2004 S 52 is about 3 kilometers in diameter, and orbits Saturn at an average distance of 26.092 Gm in 1,573.49 days, at an inclination of 162.94°, orbits in retrograde direction and eccentricity of 0.290. [2] S/2004 S 52 belongs to the Norse group and is one of the most distant moons from Saturn along with S/2004 S 26, S/2019 S 21 and S/2020 ...
