The NASA Space Agency recently announced the existence of a small asteroid named HO3 in orbit of the Sun, which keeps it trapped as a constant neighbor of our planet Earth, according to the Agency, this will remain so for the next few centuries.
In other words, this is not exactly a moon, not only because of its small size, but also because it is not orbiting the planet Earth, but the Sun. What happens is that it follows a very irregular orbit that ends up having a behavior similar to that of orbiting the Earth. HO3 is now a small asteroid that accompanies our planet.
While orbiting the Sun, this asteroid, named HO3, seems to actually circulate around the Earth, its distance is too extensive for it to be considered a true satellite of our planet, but is the best and most stable example to date of Existence of another body near the Earth, or a “almost-satellite”. The orbit of the asteroid is irregular, which makes it vary between 38 and 100 times the distance of the main Moon from our planet.
On its annual journey around the Sun, HO3 spends about half the time closest to the Sun than the Earth, and passes in front of our planet, causing us to fall behind. Its orbit is also tilted, which causes it to rise and fall once each year through the Earth’s orbital plane. With this effect, the small asteroid is captured in a “dance” with the Earth that will last, according to NASA, hundreds of years.
NASA also claims that it has about 36.5 meters and not more than 91 meters in width.
HO3 will not even be given the duration of your stay, considered a moon of our planet, since the basic definition of a natural moon or satellite, is that of a body that is trapped by the orbit of the planet, HO3 is not at all in the orbit of planet Earth, although this is affected by the gravity of our planet.
It has a very small size, approximately that of a house, and if they considered it a moon, the same for several asteroids that also orbit our planet or even the international space station.
