Another asteroid will be approaching this week and is being watched by space enthusiasts.
Asteroid 2007 FF1 A close and safe encounter with our planet is expected on April 1, according to space trackers, but it is still considered “risky.”
Any object within 4.65 million miles of us is considered a “potential hazard” by vigilant space organizations, and April fool The asteroid will pass within 4.6 million miles of our planet.
at the same time, Asteroid 2013 BO76 smashed past Earth on ThursdayMarch 24, at an astonishing 30,000 mph, according to NASA tracker.
It is 450 meters wide, about the same size as the Empire State Building and fortunately, the fast object lost our planet by some distance.
The plane is estimated to fly a safe distance of about 3.1 million miles, according to data on NASA Near Earth Objects Database.

April Fools’ Day asteroid details, recap
At a distance of about 4.5 million miles, or 19.31 lunar distances, the NEO is expected to pass safely over Earth.
However, for astronomers, this is still a dangerous distance, which is why the asteroid is constantly observed.
April Fools’ Day asteroid details continued
The asteroid, dubbed 2007 FF1, will reach its closest point to Earth on Friday, April 1.
The massive asteroid has a size of about 260 meters, or 850 feet, according to NASA’s Center for Near Earth Object Studies (CNEOS).
No other asteroid is currently being observed and is expected to pass nearby in the next two weeks compared to 2007 FF1.
April Fools’ Day asteroid details
NASA tracks a massive asteroid, traveling at an incredible speed of 30,000 miles per hour.
The asteroid, which is more than three times the size of India’s towering world-famous white marble monument, the Taj Mahal, is capable of wreaking havoc if it collides with an Earth-like planet.
NASA Upgrades Asteroid Program, Part Four
Previously, scientists had to manually perform calculations to try to figure out the impact of Yarkovsky and its effect on the asteroid’s path.
The hope is that the program can help NASA discover any of them Potentially dangerous asteroids Maybe she missed it.
NASA Upgrades Asteroid Program, Part Three
Sentry-II will finally allow scientists to take the Yarkovsky effect into account when they try to figure it out If an asteroid will hit Earth.
This was something that the original program, called Sentry, could not do.
“The fact that Sentry could not automatically handle the Yarkovsky effect was a limitation,” said Davide Farnocchia, a navigation engineer at JPL.
NASA is upgrading its asteroid software, continue
NASA will be Upgrade its 20-year-old software Using a new algorithm called Sentry-II, which will periodically scan a table of potentially dangerous asteroids and their orbits.
Sentry-II will then calculate if any of the asteroids on the table or added to the table are in danger of hitting Earth.
The new system will take into account something called the Yarkovsky effect, which indicates when an asteroid absorbs sunlight and emits it as heat.
NASA is upgrading its asteroid program
NASA has Upgrade its asteroid risk software To better discover potentially dangerous space rocks.
The US space agency’s Jet Propulsion Laboratory (JPL) uses a special type of software to assess potentially dangerous asteroids that could collide with Earth.
No imminent asteroid is on its way, but astronomers often check the sky as a precaution.
Asteroid longer than 4 blue whales
Asteroid 2007 FF1 is characterized as “at least four times the size of a blue whale” Jerusalem Post.
NEO . mission
NASA hopes to launch a Near-Earth Object (NEO) survey mission in 2026.
If the agency does this, it will eventually have a spacecraft dedicated solely to Asteroid hunting.
The hope is that the NEO Surveyor will find 90 percent of asteroids 460 feet or larger within its first decade of mission.
What is neo?
NASA considers anything that passes close to Earth’s orbit to be a Near Earth Object (NEO).
Scientists are tracking thousands of near-Earth objects to see if they are on a collision course with our planet.
NASA monitors thousands of asteroids
NASA monitors nearly 28,000 known asteroids near Earth, and New asteroid discoveries It is said to increase by the thousands every year.
On this note, NASA hopes to launch the Near-Earth Object Survey (NEO) mission in 2026.
What is a meteorite?
If a meteorite enters the Earth’s atmosphere, it begins to evaporate and becomes a meteorite.
On Earth, it would look like a streak of light in the sky, because the rock is burning, and it might look like a fireball or a “bright star.”
If a meteor does not evaporate completely and survives the journey through Earth’s atmosphere, it can land on Earth and become a meteor.
The difference between asteroids, meteorites and comets, part three
Like asteroids, a comet orbits the sun.
However, instead of being mostly made of rock, the comet contains a lot of ice and gas, which can form amazing tails left behind as a result of the evaporation of ice and dust.
“They range in width from a few miles to tens of miles, but as they orbit close to the sun, they heat up and release gases and dust into a glowing head that could be larger than a planet,” NASA mentioned.
The difference between asteroids, meteorites and comets continues
When two asteroids collide with each other, the small pieces that separate are called meteorites.
Meteorites are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks,” NASA mentioned.
The difference between asteroids, meteorites and comets
An asteroid is a small rocky body that orbits the sun.
It’s “a rocky, airless remnant left over from the early formation of our solar system about 4.6 billion years ago,” NASA reveal.
Most of them are found in the asteroid belt (between Mars and Jupiter).
But it can be found anywhere, including the path that can affect the Earth.
Solve the asteroid puzzle, continue
Currently, the theory is that Ryugu originated from the wreckage left by the collision of two larger ones asteroidsHowever, this does not explain why the asteroid contains a very high percentage of organic content. NEWSWEEK pointed out.
New results published in Astrophysical Journal Letters It indicates that Ryugu is, in fact, the remains of a dead or stalker comet.
The new theory holds that a comet is losing its icy content in a way that could have ended up having its own “unique properties”.
“Depending on whether Ryugu was originally an asteroid or a comet, it experienced a completely different environment,” lead author Miura told Newsweek.
Asteroids formed in warm regions relatively close to the Sun. On the other hand, comets formed in a cooler environment far from the Sun.”
“Supposing that Ryugu was originally an asteroid from the top of its head is to overlook the possibility that Ryugu is in a cold environment.”
Solve the asteroid puzzle?
Researchers may have “solved the mysteries surrounding the origins of the rotating, highly shaped asteroid Ryugu,” NEWSWEEK mentioned.
In fact, they may actually be the remains of a dead comet.
The space mission Hayabusa2 returned samples and images from the space rock Asteroid 162173, also known as Ryugu, in 2020.
It has been classified as a potentially hazardous asteroid by NASA’s Center for Near-Earth Object Studies.
Data from that mission showed that the asteroid had a “swivel upper shape,” and that it was a “loose pile of gravity-bound rubble” with abundant organic matter.
What is an exoplanet?
Exoplanets are planets outside our solar system. Thousands have been discovered since the eighties.
In addition to being potential sites for extraterrestrial life, they provide opportunities to better understand the evolution of the universe.
According to NASA’s outer planet DatabaseOf the 10 exoplanets found this year, six are larger than Jupiter.
paper Posted online Last month, he predicted how many exoplanets TESS will find over the course of its seven-year mission.
According to scholars, the agency A spacecraft to hunt exoplanets It will reveal over 12,000 exoplanets by 2024.
Researchers at the Massachusetts Institute of Technology made their calculations using data collected by the spacecraft worth $287 million to date.
What TESS has found so far
so far, TESS has found Nearly 5,000 worlds of all shapes and sizes, including gas giants, Neptune-like ice worlds, and the so-called super-Earths.
The mass of the giant Earth is higher than the mass of our planet below the mass of the ice giants Uranus and Neptune.
Searching for alien life
Program has been launched Transiting a satellite to survey the outer planets TESS is a space telescope designed to search for undiscovered worlds.
It’s searching an area 400 times larger than that covered by the Kepler mission, trying to find candidates that could host alien life.
How far is asteroid 138971 from Earth?
We filmed on March 4th from an estimated distance of 3 million miles.
By comparison, the Moon is only about 238,900 miles away.
A few million miles may seem very far, but it is actually very close in terms of area.
What is asteroid 138971?
Asteroid 138971 (2001 CB21) was said to be 4,265 feet wide.
This made it three times larger than the Empire State Building.
The Empire State Building is about 1,453 feet tall, so it would be paler compared to asteroid 138971 (2001 CB21).
NASA has put the asteroid on its list of “Earth approaches.”
Asteroid Crushing System, Part Three
The professor’s PI system is being designed to ascend to a nearby asteroid and pierce it with rods if necessary. These bars will contain explosives that can be detonated and Rip off the asteroid before it hits Earth.
Lubin would like the asteroid’s pieces to be less than 33 feet in diameter, should such an explosion ever be needed.
Those space rocks should then form a cloud of debris that could still hit Earth, but the hope is that much of it will disintegrate into Earth’s atmosphere instead.
The effectiveness of the PI system depends on things like the size of the asteroid and how close it was to Earth at the time of the “crush”.
Lubin says his system could one day orbit Earth and be ready for any sudden doomsday asteroids that have the potential to reach us.
Asteroid crash system continues
Professor Lubin thinks this will be our best chance Protect the Earth from a devastating asteroid collision.
according to universe todayThe professor previously presented his defense system at the 2021 Planetary Defense Conference and his idea has been spotted by NASA.
He is now a Phase 1 Award recipient in the NASA Innovative Advanced Concepts (NIAC) Program.
Lubin previously noted: “So far, humanity has escaped a large-scale catastrophe as visited on our previous tenants, but counting on being ‘lucky’ is a poor long-term strategy.”
We don’t want to go the way of the dinosaurs, after all.
