Asteroid Bennu: For a long time, the scientific fraternity has been pondering over how water was formed on Earth and where it came from. Apart from this, where did life come from? Amidst all this, discussions are going on regarding the asteroid i.e. Asteroid Binnu.

Asteroid Existence: Asteroid Bennu is once again in the news. Samples collected from this 4.5 billion year old asteroid Bennu have been brought to Earth. These samples are being studied by researchers at Curtin University, who are part of an international team, to understand the origins of our solar system. Actually, what the scientists who did this research have said is quite true.

He said that this asteroid probably existed even before the birth of the solar system and it may have brought water and life to the Earth.

In fact, according to a report by Viaan News, NASA’s billion-dollar Osiris-Rex mission completed its seven-year journey in September last year and returned with samples from asteroid Bennu. Its samples were sent to various research laboratories around the world, including Curtin. Now a new study has revealed some surprising findings from the samples.

Interesting discoveries

According to the report, in this study published in the journal ‘Meteoritics and Planetary Science’, it was told that scientists saw some amazing things in the asteroid samples. They found dark colored particles ranging from the size of dust to about 3.5 centimeters long in these samples. Some light colored particles and stones were also found along with them. in these samples

Was benu present before solar system

Experts say the analysis shows that Bennu is one of the most chemically primitive objects, similar in composition to the Sun’s visible surface. On this basis, it is being estimated whether Binnu already existed before the solar system. Although this cannot be confirmed, a deep investigation is still necessary.

Not only this, scientists found that the Bennu asteroid is made differently from the planets. Its chemical composition is slightly different from that of the Sun. This tells us that different things happened after the formation of Bennu. When scientists examined samples of Bennu, they found something else too. They found that it also contained minerals made of water and carbon.

This means that such asteroids could play an important role in delivering water and the building blocks of life to Earth.🌍

Let us tell you that a long time ago, the American space agency NASA has placed this giant asteroid named Bennu in the dangerous category. Since then, continuous studies are being done on this asteroid. It is believed that the asteroid named Bennu must have separated from a larger asteroid 2 billion to 700 million years ago.

What is so special about asteroid Bennu?

Bennu is a carbon-rich asteroid that is about one-third of a mile (half a kilometer) wide at its equator. An ancient relic of our solar system’s early days, asteroid Bennu has seen more than 4.5 billion years of history.

Where is Bennu’s asteroid now?

Asteroid 101955 Bennu (1999 RQ36) is currently in the constellation of Scorpius. The current Right Ascension is 16h 32m 23s and the Declination is -31° 01′ 35” .

What is the NASA mission of Bennu?

OSIRIS-REx left Bennu on 10 May 2021 and returned its sample to Earth on 24 September 2023, subsequently starting its extended mission to study 99942 Apophis, where it will arrive in April 2029. Bennu was chosen as the target of study because it is a “time capsule” from the birth of the Solar System

Does Bennu have gravity?

0.00009807 m/s²101955 Bennu/Gravity

Roughly the height of a skyscraper, Bennu’s loose surface materials are held together by an incredibly weak gravitational field – with a minute tug less than one-hundred-thousandth the pull of Earth

there water on Bennu?

What class of asteroid is Bennu?

Bennu is a B-type asteroid with a ~500 meter diameter. It completes an orbit around the Sun every 436.604 days (1.2 years) and every 6 years comes very close to Earth, within 0.002 AU. These close encounters give Bennu a high probability of impacting Earth in the late 22nd century.

Why was Bennu chosen?

So, of the more than one million known asteroids in our solar system, why did NASA choose the near-Earth asteroid Bennu for its target? Three factors made Bennu ideal: proximity to Earth, the right size and spin rate, and a carbon-rich composition.

Could you stand on Bennu?

It turns out that the particles making up Bennu’s exterior are so loosely packed and lightly bound to each other that if a person were to step onto Bennu they would feel very little resistance – as if stepping into a pit of plastic balls that are popular play areas for kids.

What is unusual about asteroid Bennu?

A special kind of carbon-rich asteroid, Bennu is believed to contain organic compounds as old as the solar system itself, which, scientists hope, will help shed some light on the origins of life on our planet

What are the facts about Bennu?

Bennu Facts:

• Equatorial Diameter: ~500 m.
• Polar Diameter: ~510 m.
• Average Speed: 63,000 mph.
• Rotation Period: 4.3 hrs.
• Orbital Period: 1.2 yrs.
• Orbital Inclination: 6 degrees.
• Earth Approach: Bennu comes close to Earth every 6 yrs.

Bennu in the solar system?

The mission aimed to explore the asteroid Bennu, believed to have existed before the birth of the solar system. The findings have been published in Meteoritics and Planetary Science

Bennu hit Earth?

Dubbed Bennu, the massive 4.5 billion-year-old space rock is expected to make a close flyby in the year 2182. While the space agency said there is only a . 05 percent chance of Bennu colliding with our planet, NASA is working on preparations for this potential outcome

Which asteroid killed dinosaurs?

Becky Ferreira previously reported on the search for the origin of the Chicxulub asteroid. Scientists have discovered new evidence that the rock that slammed into Earth 66 million years ago, abruptly ending the age of dinosaurs, was a bit of an oddball

Where is Bennu asteroid located?

Asteroid 101955 Bennu (1999 RQ36) is in the constellation of Scorpius, at a distance of 100,283,191.7 kilometers from Earth. The current Right Ascension is 16h 47m 34s and the Declination is -30° 37′ 26” (apparent coordinates).

While there is no evidence of an alien connection to the asteroid Bennu, the asteroid’s materials and history are significant to the study of life on Earth:
