Earth possesses two known trojans, (706765) 2010 TK 7 and (614689) 2020 XL 5, which are small Solar System bodies also orbiting the Sun in a 1:1 resonance with Earth, rather than the Earth itself, but staying with the gravitationally-stable Earth–Sun leading L 4 Lagrange point. Tadpole orbit of 2010 TK 7 from 1600 to 2500 - relative to Sun ...
There has not yet been an orbiter around Uranus or Neptune for long-term study of their moons. For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center [6] and JPL Solar System Dynamics, [5] give somewhat ...
The Moon orbiting around Earth (observed by the Deep Space Climate Observatory) A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, a derivation from the Moon of Earth.
Earth currently has an estimated seven quasi-moons—one of which, Kamo‘oalewa, is thought to be a chunk of the moon. Occasionally, Earth will even capture mini-moons, or tiny asteroids that are ...
Among the other dwarf planets, Ceres has no known moons. It is 90 percent certain that Ceres has no moons larger than 1 km in size, assuming that they would have the same albedo as Ceres itself. [6] Eris has one large known moon, Dysnomia. Accurately determining its size is difficult: one indicative estimate of its radius is 350 ± 57.5 km. [7]
An asteroid that orbited near Earth for a few months as a mini-moon may be a chunk of the ... the object’s orbit around the sun is similar to Earth’s, suggesting that 2024 PT5 originated from ...
Charon and Earth’s moon are both a large fraction of the size of the main body they orbit, which is unlike other smaller moons orbiting planets throughout our solar system. (Pluto has four ...
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
