Asteroid 2007 FF1 LIVE – NASA says 'Hazardous' space rock makes ‘close approach’ to Earth at 29,800mph
AN asteroid made a "close approach" to Earth on April 1, 2022, while being watched closely by space enthusiasts.
Asteroid 2007 FF1 made a "hazardous" close encounter with our planet around 4.35pm on Friday – flying within approximately 4.6 million miles of Earth and at a speed of 29,800 mph, LiveScience reported.
Any object that comes within 4.65million miles of us is considered "potentially hazardous" by cautious space organizations.
Meanwhile, Asteroid 2013 BO76 hurtled past Earth on Thursday, March 24, at a staggering 30,000 miles per hour, according to Nasa trackers.
At up to 450 meters across, it's roughly the same size as the Empire State Building and fortunately, the speedy object missed our planet by some distance.
It was estimated to fly by at a safe distance of around 3.1million miles, according to data on Nasa's Near-Earth Object database.

Even small asteroids can be dangerous
In February 2013, an asteroid that NASA previously described as “house-sized,” so relatively small next to Asteroid 2015 DR215, exploded in the skies, Newsweek noted.
It exploded over the Russian city of Chelyabinsk after it entered Earth’s atmosphere at around 40,000 miles per hour, and released a shock wave that obliterated windows over 200 square miles when it exploded.

Saving Earth from asteroids, continued
Nasa said: “DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact.”
The DART craft should hit a small asteroid called Dimorphos in September with the ultimate aim of moving it off course.

Saving Earth from asteroids
Some experts are worried that Earth isn’t yet ready to defend itself from potentially deadly asteroids.
SpaceX CEO Elon Musk once sparked concern when he tweeted: “a big rock will hit Earth eventually & we currently have no defense.”
Nasa is looking into having some defense methods set up, however.
It recently launched its Double Asteroid Redirection Test mission.

If an asteroid hit the Earth, conclusion
“So you burn things, kill everything in the ocean, and freeze the Earth, and it goes through about two years of constant winter,” Scharringhausen added.
He doesn’t think that all life on Earth would die after a large asteroid impact, since some small creatures survived the asteroid strike that once killed the dinosaurs.
Scharringhausen explained: “Not everything will die. If we’re thinking about people, the way to survive would be to get underground.”
“You could maybe ride it out in a bunker if you’ve got the supplies to make it through that period of winter where you can’t grow any edible food.”
“Maybe the finicky crops that humans like to grow won’t come through it so well, but there’s that seed repository, so if those are well-protected enough, you could get agriculture restarted.”

What would happen if an asteroid hit Earth, continued
Experts think we’d experience fires, shock waves, heat radiation, a large crater, acid rain, and giant tsunamis if such an asteroid ended up hitting the water.
Britt Scharringhausen, an associate professor of physics and astronomy at Beloit College, told Inverse: “All of the ash from the fires and all of the finer-grain debris from the impact will hang out in the atmosphere for a long time, and we get what’s called an impact winter.”
“It’s going to block the sunlight, and all that ash falling into the ocean acidifies the top layers.”

What would happen if an asteroid hit Earth?
Depending on the size of the space rock, an asteroid impact on the Earth could be an extinction-level event, and researchers have created simulations to see just how bad it could be.
Not all asteroids would mean the end of humanity and, in fact, a space rock would have to be pretty large to kill us all.
If an asteroid the size of the one that likely killed the dinosaurs hit Earth today, things would instantly change due to the force of the impact and its knock-on effect on the environment.

Asteroid mystery solved, continued
Currently, the theory is that Ryugu originated from debris left by the collision of two larger asteroids, but that doesn’t explain why the asteroid is so high in organic content, Newsweek noted.
New findings published in The Astrophysical Journal Letters suggest Ryugu is, in fact, the remains of a dead or extinguished comet.
The new theory involves the comet losing its ice content in a way that could have ended up with it having the “unique characteristics” it does.
Lead author Miura told Newsweek: “Depending on whether Ryugu was originally an asteroid or a comet, it experienced a very different environment.”
“Asteroids formed in warm regions relatively close to the sun. On the other hand, comets formed in a cooler environment away from the sun.”
“To assume off the top of one’s head that Ryugu was originally an asteroid is to overlook the possibility that Ryugu may have been in a cold environment.”

Asteroid mystery solved?
Researchers may have “solved mysteries surrounding the origins of the spinning top-shaped asteroid Ryugu,” Newsweek reported.
In fact, it may actually be the remnants of a dead comet.
Space mission Hayabusa2 returned samples and images from the space rock Asteroid 162173, also known as Ryugu, in 2020.
It is classified as a potentially hazardous asteroid by NASA’s Center for Near-Earth Objects Studies.
Data from that mission showed that the asteroid has a “spinning top shape,” and that it is “a loose pile of gravitationally bound rubble” with plentiful organic material.

Types of asteroids: M-types
The M-type asteroids (nickel-iron) are made of metal. The compositional variations between asteroids are linked to how distant they originated from the Sun.
After they formed and partially melted, some endured tremendous temperatures, with iron sinking to the center and driving basaltic (volcanic) lava to the surface.
- Amanda Castro
Types of asteroids: S-types
S-type (stony) asteroids are made up of nickel-iron silicate minerals.
- Amanda Castro
Types of asteroids: C-Type
C-Type (chondrite) are the most common asteroids. They are most likely made up of clay and silicate rocks and have a black look. They are among the solar system’s oldest ancient things.

St Patrick’s Day asteroids, continued
A 78 foot asteroid called 2022 EU3 was the last close approach asteroid to shoot past Earth on St Patrick’s Day.
Asteroid 2022 EU3 came within 3.4 million miles of Earth.
The other two asteroids to make the St Paddy’s Day list were called 2022 EM6 and 2022 EU6.
They’re said to be about 200 feet and 183 feet large, respectively.

St Patrick’s Day asteroids
Before Asteroid 2013 BO76 flew by, Nasa was watching five close approach asteroids around St Patrick’s Day.
All of the asteroids made their close approaches to Earth that morning.
Asteroid 2019 PH1 was the largest at 203 feet wide.
The closest approach came from a slightly smaller space rock called 2022 EL6.

Youngest asteroids ever found in Solar System
Researchers have found a pair of asteroids orbiting the Sun that was formed under 300 years ago.
Details of the Astronomical discovery were published in a report in the Monthly Notices of the Royal Astronomical Society.
The twin asteroids – dubbed 2019 PR2 and 2019 QR6 – are the youngest found in our solar system.
“It’s very exciting to find such a young asteroid pair that was formed only about 300 years ago, which was like this morning – not even yesterday – in astronomical timescales,” astronomer Petr Fatka of the Astronomical Institute of the Czech Academy of Sciences said.

Asteroid captured in rare shot, continued
Ahead of the relatively close approach, scientists at the Virtual Telescope Project (VTP) captured an image of the asteroid in the night sky.
It was imaged using one of the Italian facility's largest scopes at a distance of about 7.2million miles from Earth.
"This about 200 meters large asteroid will reach its minimum distance from us on April 1 at 21:35 UTC," VTP founder Gianluca Masi wrote.
"Of course, there are no risks at all for our planet."
