Scientists just found the origin of the second moon

Precise News

Earth’s “second moon”—as asteroid called Kamo’oalewa—appears to have come from the moon itself.
Scientists have concluded this using computer models, revealing its origin as the Giordano Bruno crater on the moon’s far side.
Meet Kamo’oalewa Kamo’oalewa, also called 2016 HO3 and meaning “oscillating celestial object” in Hawaiian, is about 130 to 330 feet (40 to 100 meters) across—about the size of The Statue of Liberty.
Giordano Bruno Crater The asteroid comes from Giordano Bruno crater on the far side of the moon, according to a paper published this week in Nature Astronomy.
A 14-mile (22-kilometer) wide impact crater, Giordano Bruno crater is thought to be the youngest crater of its size or larger on the moon’s surface.
China’s Mission Scientists will soon know more about Earth’s “second moon.” Next year, Kamo’oalewa will be visited by Tianwen-2, China’s first asteroid sampling mission.
‘Dark Side’ Of The Moon Giordano Bruno crater is on the moon’s far side, often mistakenly called its “dark side.” Despite it being a term used in popular culture, the dark side of the moon has no technical meaning.
These are the phases of the moon, but only at full moon is the far side completely dark.


The Kamo’oalewa asteroid, which is known as Earth’s “second moon,” appears to have originated from the moon.

Using computer simulations, scientists have come to this conclusion, identifying the Giordano Bruno crater on the moon’s far side as its source.

It is commonly believed that near-Earth asteroids, like Kamo’oalewa, originate from the Main Asteroid Belt, which lies between the orbits of Mars and Jupiter.

Become acquainted with Kamo’oalewa.

Like the Statue of Liberty, Kamo’oalewa, also known as 2016 HO3, is an approximately 130 to 330 foot (40 to 100 meter) across “oscillating celestial object” in Hawaiian. Pan-STARRS, a network of telescopes in Hawaii intended to detect and monitor New England Arches, made the discovery in 2016. We currently know of about 250,000 NEAs.

Because Kamo’oalewa rotates around the sun rather than the Earth, it is considered a quasi-satellite of Earth. It resonates 1:1 with Earth, moving in time with it.

Bruno Giordano Crater.

A study this week in Nature Astronomy claims that the asteroid originated in the Giordano Bruno crater on the moon’s far side.

The Giordano Bruno impact crater, which is 22 kilometers (14 miles) wide, is believed to be the youngest crater on the moon of a similar size. Scientists believe that between one million and ten million years ago, an asteroid with a diameter of about one mile (1 point 6 kilometers) struck the moon, causing the impact.

Researchers modeled the kind of impact that could create and expel something the size of Kamo’oalewa using numerical simulations. Science claims that weeks of computation on supercomputers were required for the project in order to investigate every possibility.

The idea that Kamo’oalewa originated from the moon has been floated before. Kamo’oalewa may be a fragment of the moon, according to a group of University of Arizona astronomers who used Arizona’s Large Binocular Telescope Observatory in 2021. This was because it reflected light that was different from any other NEA’s spectrum. Another research team came to the same conclusion last year after finding that, despite the likelihood being slim, lunar fragments from an impact occurring within the last few million years may make their way into orbits similar to Kamo’oalewa.

Despite the fact that asteroids and meteorites are the source of all of the moon’s craters, the lunar material that is ejected during an impact usually returns to the lunar surface.

China’s Mission.

The “second moon” of Earth will soon be better understood by scientists. China’s first asteroid sampling mission, Tianwen-2, is scheduled to visit Kamo’oalewa next year. As the most prevalent but least understood small body, an asteroid tens of meters in size will be the subject of the first mission to study it.

It is anticipated that Kamo’oalewa will spend millions of years orbiting the Earth.

Moon’s “Dark Side.”.

The moon’s far side, sometimes erroneously referred to as the “dark side,” is home to Giordano Bruno Crater. Though it’s a phrase from popular culture, “the dark side of the moon” has no scientific significance. Only the near side of the moon is visible to us because it is tidally locked to Earth.

Nevertheless, as the moon revolves around Earth, half of it is continuously illuminated by the sun, and our perspective of it varies throughout the day. These are the moon’s phases; the far side is never entirely dark except during a full moon.

I’m wishing you big eyes and clear skies.
