They found a unique moon outside our solar system. We’ve only seen two in the universe so far

The solar system is home at most for 640 months, of which 444 do not accompany any planet, but orbit the smaller bodies in the solar system. While there is no reason to believe that the months were different in other systems, we haven’t discovered much of them yet.

Only the second discovered exomesiac

In fact, we have so far only found one candidate for the so-called exomesiac – in 2017. Now, thanks to a study published in the journal natural astronomy, we have evidence of another moon orbiting a distant planet. The portal drew attention to the topic ScienceAlert.


This discovery was made by experts from the Cool Worlds Laboratory, located on the campus of Columbia University, led by David Kipping. The portal also noted that the aforementioned expert also took care of discovering the first exomesiac candidate in 2017. Phys.

Although more than 10,000 exoplanet candidates have been identified so far, spotting moons orbiting these distant worlds is by no means easy. The discovery of the super-message of the planet orbiting Kepler 1708 b, 5,500 light-years from Earth, has caused an uproar in the scientific community.

What do we know about myths?

All the collected data indicate that this is a real giant. The discovered super-planet called Kepler-1708b-i is up to 2.6 times larger than our home planet and likely has a composition similar to Neptune. If this hypothesis is correct, it is possible that the Moon began its life as a planet, but over time, for some unspecified reason, was pulled into the orbit of a larger planet.

The planet in question in this case is Kepler 1708 b, which is similar in size to Jupiter. The results show that the discovered Kepler-1708b-i superoxide is similar to the first exomesiac candidate, Kepler-1625b-i. It is located 8000 light-years away and the size and mass of Neptune, orbiting the planet several times the mass of Jupiter.

Nothing we’ve seen yet

Thus, the two detected outer states are very different from the moons in our solar system, but according to astronomer David Kipping, this is not unusual. According to him, the first finds usually consisted of such “eccentrics”.

The new candidate for exomesiac was discovered in data collected by the Kepler space observatory, which has been discontinued for some time. In data from the observatory, scientists closely monitored 70 large gaseous exoplanets, with Kepler 1708b, the only planet on the list, to show a “moon-like signal.”

However, we will have to wait to definitively confirm whether the discovered object is really more exotic. Many other observations will have to be made with other space telescopes, which could take several years.

Also worth noting is the fact that the first candidate discovered for exomesic to date has not been conclusively confirmed. Some experts even believe that this is an artifact due to data reduction.

As these candidates are discovered, new questions and problems also arise. Astronomers aren’t sure how a planetary system filled with gaseous planets and gaseous moons formed. Since there is nothing like this in the solar system, it is likely that the mechanism of formation of such a system is very different from that which determined the composition of the months of the solar system.
