Scholars of small celestial bodies in the solar system interpret them as unique celestial bodies in

After studying the asteroid Cleopatra, astronomers determined that the asteroid was a unique object in the solar system.

Astronomers, in a study of this asteroid with its moons and unusual shape, found that science has made a lot of progress thanks to the study of strange outliers. Cleopatra is one of them, and understanding this complex multi-asteroid system can help us learn more about our solar system.

The asteroid Cleopatra orbits the Sun in the asteroid belt between Mars and Jupiter. Astronomers call it the "dogbone asteroid" because it was observed about 20 years ago that it had large heads at both ends and was connected by a thick "neck". Two moons named by astronomers after the children of the Queen of Egypt - Alex Hillis and Cleo Selon - orbit Cleopatra.

In order to learn more about Cleopatra, astronomy uses asteroids taken at different times**, which are taken with spherical instruments**. Since the asteroid is spinning, they were able to observe it from different angles and create the most accurate three-dimensional model to date. They described the shape and volume of the asteroid's dog bones, found that one of the heads was larger than the other, and determined that the asteroid was about 270 kilometers long, about half the length of the English Channel.

In the second study, the team reported on how they used sphere observations to find the correct orbit of the two Cleopatra moons. Previous studies have estimated orbits, but new observations show that the satellites are not in the position of the earlier data.

This is because if the orbit of the satellite is wrong, then everything is wrong, including the mass of Cleopatra. Thanks to new observations and sophisticated models, the team succeeded in accurately describing the effect of Cleopatra's gravitational pull on the satellite's motion and determining the complex orbits of Alex Hillis and Cleocheron. This allowed them to calculate the mass of the asteroid and found that it was 35% lower than previous estimates.

Combined with new estimates of volume and mass, astronomers were able to calculate a new value for the asteroid's density, which was less than half the density of iron, and turned out to be lower than previously thought. Cleopatra has a low density and is believed to have a metallic component, which indicates that it has a porous structure. This means that it is most likely formed when matter reaccumulates after a huge impact.

The structure of Cleopatra and the rotation square elevation also illustrate how its two moons were formed. The asteroid is spinning at almost a critical speed, beyond which it will begin to scatter, and even a tiny impact can throw debris off the surface. These rubbles may have subsequently formed Alex Hillis and Cleocheron, meaning that Cleopatra had truly given birth to its own moon.

The Sun is intermediate, the four gas planets are protons, Venus, the Earth, and Mars are intermediate products, and there is the possibility of alternating organisms, and Mercury may be prepared by the solar energy**. Always feel like molecules, cells, atoms.

Can the living system, when viewed from outside the solar system, discover what are the characteristics of life in the solar system?

The solar system is a small universe, built for the origin of life, the sun is an electromagnetic emitter, and the sunlight hits the earth to provide energy for life. The earth is like a playground of life, where countless microorganisms (including humans) play the cycle of life and death, providing energy and nourishment for the spiritual world and renting back .......

The sun is a high-voltage electromagnetic field, which collects various gold particles around it, and purifies nuclear substances in its furnace to produce high-temperature electricity** and burns it to form a fireball, the sun, named a star.

According to CNET, perspective is important, even when it comes to astronomy. Sometimes the whole planet can just be an optical illusion. This is apparently what happened with HD 131399AB, an exoplanet the size of Jupiter that now appears to have never existed.

Recent observations have revealed that what looks like a planet is actually a celestial object in the background – possibly a star light-years away – and on Thursday the team had withdrawn the HD 131399ab related to it published in the journal Science.

Kevin Wagner, lead author at the University of Arizona, said upon learning that the planet was a phantom: "It's pretty shocking. Some unlikely parameters about this background object are arranged to make it look very much like a planet.

The planet, which would now have to be removed from the annals of astronomy, would have been one of the most unusual and noteworthy exoplanets ever discovered. The discovery was first announced in 2016, when it caught the attention of researchers, as at the time it appeared to be the first known planet orbiting three "suns".

As you may recall, Luke Skywalker's fictional hometown of Tatooine has two suns, so HD 131399ab is even stranger than the one in **. Recent observations have shown that Wagner and colleagues really saw something in the distant background, and they carefully analyzed it over a longer period of time to confirm that the planet never really existed.

Wagner said this is a useful lesson that will ultimately improve astronomy and the search for exoplanets.

"The background is not stationary, and sometimes a very fast-moving star can align its motion and thus pass our usual test of common proper motion," he said. This possibility has begun to be considered in recent studies, and in my opinion this is a positive result. ”

According to New Atlas,Astronomers have discovered the first known quadruple asteroid system. A team from Thailand and France discovered a third moon orbiting the main-belt asteroid Elektra, putting the object in the record books.

Most asteroids travel alone, but some orbit in pairs under gravitational pull – usually a small body orbiting a large body. In rare cases, a triple asteroid system has been discovered, with two moons orbiting a larger host star. This is the complexity of the asteroid system, until now.

The asteroid Elektra, which orbits the Sun in the outer region of the main asteroid belt, was first discovered in 1873 and is quite large in diameter, about 200 kilometers (124 miles). However, its first moon was not discovered until 2003, when astronomers found a rock 6 kilometers (miles) in diameter orbiting it every five days at a distance of about 1,300 kilometers (808 miles). Its second moon emerged in 2014 – a smaller rock measuring just 2 kilometers (miles) in diameter that orbits 500 kilometers (310 miles) from Elektra every other day.

Now astronomers have discovered Elektra's third moon, making Elektra a quadruple asteroid system. The satellite is only one kilometer (1 mile) in diameter, orbits the main body every 16 hours, and travels a distance of 344 kilometers (214 miles). The orbits of the other two satellites are roughly circular, while the third follows an eccentric egg-shaped orbit.

The discovery was made by Dr. Anthony Berdeu, who applied a new algorithm he developed to archival data from the Very Large Telescope (VLT) in Chile. These algorithms reduce the bright light from the main asteroid and remove it from the image, making the fainter objects clearly visible. When this was applied to the 2014 dataset where the second satellite was discovered, Berdeu discovered the third.

To confirm this, the team applied the algorithm to two other Elektra's datasets, and sure enough, a third satellite was visible in each dataset.

Elektra may be the first quadruple asteroid system to be discovered, but it may not be the last. The team said the method could be used to image other asteroids and solar system objects, making it possible to find other hidden moons.

The study was published in the journal Astronomy & Astrophysics.
