"Interstellar Visitor" Oromo

Since the advent of the era of peaceful development, mankind has been exploring space for decades. Although the knowledge about space is still insignificant in the vastness of the universe, some information about the moon, the sun, and the solar system is available. However, some information about the Moon, the Sun, and the solar system has gradually become clear.

In particular, the knowledge of the solar system, which is a large space, has developed considerably. The solar system, which orbits the Milky Way, includes within it the star Sun, eight planets and nearly five hundred moons, and more than a million asteroids, plus a few dwarf planets and comets, who make up the solar system as we know it.

However, the Pan-STARRS telescope on the island of Hawaii discovered visitors from outside our solar system in 2017.

The appearance of the Oromo

The Oromo first came into view in October 2017, when a telescope on Hawaii Island discovered the Oromo about 30 million kilometers from Earth. When the observers discovered Omoor, they thought it was a comet and gave it the number C/2017 U1.

The observation should have been as unusual as any other comet, but five days later the Very Large Telescope photographed it differently. After getting a picture of it, people were surprised to find that the comet, named C/2017 U1, did not have a "wispy hair", which is commonly known as a broom tail. The dull C/2017 U1 began to make people overthrow the perception of the previous days and recognize it from the comet's perspective outside the world.

Scientists speculate that this newly discovered star is not a comet and that its main body is not ice, but more likely rock. So, with this perception, it changed to another identity, that of an asteroid.

However, it was soon discovered that it was different: the orbit and speed of the star were completely different from other objects in our solar system. Not only that, but scientists later found that its orbital speed was not entirely solar, but had also been influenced by other planets.

As a result, the planet got rid of the name C/2017 U1 and was given the special name 1I/Oumuamua, an international name, that in Chinese means "Oumuamua".

In the native Hawaiian language, Oumuamua means "messenger from afar", while in Chinese, "O" means mysterious, and "stranger" means strange. A mysterious visitor to our solar system from another galaxy was observed by humans in 2017.

Since Ao Mor was the first alien object to enter our solar system, it was studied by various countries.

Finally, more detailed information about the Oromo has appeared before us.

Information about Oromo

It is not surprising that the Hawaiian observers initially identified it as a comet, but the shape of Omo is indeed very different from other stars. It is about 400 meters long and 40 meters wide, and since more specific photos are not available, we only know that the surface of Ao Mor is solid, and we do not know whether it is rocky or metallic, as previously speculated.

In addition to its external appearance, the trajectory of the Oromo is also puzzling.

It is presumed that the Oromo is rushing into the solar system from the direction of Lyrae at a speed of 26 km/s. It is also presumed that the orbit of the Oromo is much faster than that of the solar system. This speed, which far exceeds that of other small bodies in the solar system, has raised doubts about the identity of the Oromo.

However, when it reached perihelion in September 2017, it did not approach the Sun but chose to turn away. in October, it was close to more than 30,000 km from Earth, and by early November, it had already passed over the orbit of Mars. In late December, even with the largest telescopes to observe it, can not be found.

Scientists can only project its trajectory based on the behavior of the Oromo gradually away from Earth, perhaps after this year, the Oromo will cross the orbit of Neptune.

The newly discovered "extraterrestrial visitor" is not only moving away from the solar system, but its speed has also changed. When "visiting" the Sun, the speed of the stranger is about 26km per second, but when it began to move away from the Sun, its speed gradually rose, becoming 40km per second, according to such a speed, and then 7,500 years of the stranger will directly leave the solar system. Such a large speed change, in people's view, as if it is "slamming on the gas" general. Why would the Oromo make such a big shift? Scientists are also very confused.

What is Oromo?

Because of its eagerness to escape from the solar system and its fast orbit, it has only been observed for a month or so. In addition, from the data observed in 2018, the orbit of the stranger also deviates from scientists' calculations by tens of thousands of kilometers, which makes the stranger even more mysterious.

For this reason, the phenomenon of Oromo's "escape" has led to the topic of what Oromo is.

Speculation one suggests that the galaxy in which the Oromo is located is a cluster of stars near our solar system, formed in a planetary disk in that cluster. Forty million years ago, Oromo was ejected by a planet and left at a speed of 2 km/s. Forty million years later, the Oromo arrived in a solar system that could be observed by humans.

However, this speculation about the identity of the Oromo is not fully believed. Not to mention the Ormolu in the solar system's trajectory like a parabola, just after throwing it gradually increased speed and break free from the gravitational pull of the star to the solar system is puzzling.

You know, the mass of the star is much larger than the planets, so other objects will be affected by its gravity. However, Oromo was able to escape the gravity of the original star and flew through to the solar system.

Moreover, after reaching the perihelion, the Oromo undergoes a slingshot effect and moves away from the Sun at a much faster speed. Could it be that the Oromo is not subject to the gravitational pull of the Sun?

For this reason, some scientists believe that the Oromo is an alien civilization vehicle, which approaches the sun to replenish its energy and then chooses to leave after sightseeing.

Of course, this hypothesis does not have much support. In addition, some scientists believe that the Oromo is a fragment of an emerging celestial body, which is why its shape is so special.

Until now, there is still no definite answer to the question of what Oromo is and why it left the solar system in a fiery manner.

Although currently unknowable, there is a more plausible way for scientists to figure out this answer. This year, scientists from the UK and the US have proposed a "catch up with the stranger" scenario, in which they expect to launch a probe in 2028 and then catch up with the stranger, probably in 2050, the probe will catch up with the stranger.

If so, then the mystery of the stranger will be solved, it is not far from us.
