Comparing the size of the large moons in our solar system through Emily Lakdaulla.
Most of the planets in our solar system have orbital moons and even some asteroids have their own moons. But are there moons ? Is it possible? Could there be so-called submons ? Carnegie Science's Juna Collmeyer said her 4-year-old son had raised her interest in this subject by asking this seemingly logical question. The question is simple enough. If most other objects in the solar system can have moons, why not the moons themselves?
Collmeier decided to try to answer the question with his colleague Sean Raymond of the University of Bordeaux. Their results have already been published in a new article published in February 2019 on the monthly announcements of the Royal Astronomical Society .
As explained by Raymond in Carnegie's statement:
Planets circling the orbit of stars and moons, so it's natural to ask if the smaller moons can travel larger orbits.
So far, no moons have been detected in orbit of any of the moons most likely considered to be supporting them. Calisto, the moons of Saturn Titan and Jape and the moon on Earth. According to Kolmayer, the lack of known moons in our solar system, even in orbit around the moons that could theoretically support such objects, can provide us with clues about how our own and neighboring planets are formed, for which there are still many questions.

Researchers found that only large broad-band satellites from their host planets could accept submons. Generally, all the subterfuge, which circulates around the smaller moons closer to their planet, could destabilize their orbits from the tidal forces. The big moon of Jupiter Calisto, the moon of Saturn Titan, another moon of Saturn called Jape and the moon on Earth all theoretically can have swords, so why?
There may be other sources of submergence instability, such as the uneven mass concentration in the earth's crust, according to the researchers.
Even asteroids can have moons like 2004 BL86. Its diameter is about 1100 feet (325 meters) and its moon is small, 70 meters wide. Part of the answer may also relate to how the primary moons were originally formed. It is believed that the moon on Earth is born from a collision between the Earth and another Mars-sized body – and that collisions may have helped Earth's life begin. But some other moons, like those that circle around Jupiter and Saturn, come from the same cloud of gas and dust from which the planets themselves have formed. And, of course, this could lead to ongoing efforts to understand how planetary systems are evolving elsewhere, and how our own solar system fits into thousands of others discovered by planet-hunting missions. many or even most of the cases, there are many factors that make the orbits of substitutions essentially unstable. To know whether this is true or not, you may have to wait for the discoveries of the moons that run around distant exoplanets. The moons themselves are much more difficult to detect, and only one promising candidate has been discovered – a possible exomus in orbit around the Jupiter Kepler-1625b exoplanet. This possible moon, the size of Neptune, is big enough and far enough from its planet that it should also be possible to replace it. Astronomers will have to check that the initial moon first – if it exists – before looking for some submons.

Although the Moon of the Earth no longer has a submarine boat, in the future, according to the researchers, artificially may have planned the NASA Lunar Portal. The Lunar Gateway will help to establish the presence of humanity in deep space as stated by William Gusttenmayer, a law enforcement officer at the NASA headquarters mission
The Gate will give us a strategic presence in the cyberspace . It will lead our business with trade and international partners and help us explore the Moon and its resources. In the end, we will translate this experience into the human missions of Mars.
Raymond has written a cool poem about moon moons that you can enjoy on his blog here. is fascinating, although we have not yet found any examples. This new study by Carnegie Science shows that it is possible but only under appropriate circumstances.
