This asteroid's orbit keeps it near the Earth, but not orbiting it in the usual sense. When analyzing its orbit from the perspective of different bodies, the presumed quasi-satellite does seem to have a more stable location near the Earth The orbit of 2020 CD 3 around the Earth. The white band is the orbit of the Moon.
They are very difficult to observe from Earth [7] but may be visible to the unaided eye in an exceptionally dark and clear night sky. Most claimed observations have been made from deserts, at sea, or from mountains. [11] The clouds appear somewhat redder than the gegenschein, indicating that they may be made of a different kind of particle. [7]
The giant planets have extensive systems of natural satellites, including half a dozen comparable in size to Earth's Moon: the four Galilean moons, Saturn's Titan, and Neptune's Triton. Saturn has an additional six mid-sized natural satellites massive enough to have achieved hydrostatic equilibrium , and Uranus has five.
Earth is getting a temporary second "mini moon," a.k.a. the 2024 PT5 asteroid. Here's how you can see it and if it will affect your astrological star sign.

Stars in the night sky. The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon. Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing.
Now, a new study from scientists at the University of Nevada is adding some complexity to this immensely chaotic moment in Earth’s history by suggesting that, for a brief time, the Earth-Moon ...
Gravitational accelerations at L 4. The Hill sphere is the region in which an astronomical body dominates the attraction of satellites. Of the Solar System planets, Neptune and Uranus have the largest Hill spheres, due to the lessened gravitational influence of the Sun at their far orbits, however all of the giant planets have Hill spheres in the vicinity of 100 million kilometres in radius.
