NASA’s chilling secret plan has been revealed ahead of the “close approach” of a space rock and asteroid 2015 DR215.
The agency said an asteroid simulation exercise was conducted in February to assess damage from an asteroid crashing into Earth, according to a new report. report.
The news was revealed a day before an asteroid makes a “close approach” to Earth on Friday, but another will swing very close to our planet this weekend, and you can watch it live.
Asteroid 2022 ES3 will come between the Moon and Earth around 2:18 p.m. ET on Sunday, March 13. Newsweek reported.
The Virtual Telescope Project will host a live stream of the asteroid’s “very close, but sure, encounter with us” on its Web TV page starting at 6:30 p.m. UTC on Sunday (1:30 p.m. ET).
Meanwhile, NASA experts expected asteroid 2015 DR215 to fly past Earth in the early hours of Friday morning, with the agency “close approach” table showing the exact time as 6.40 UTC.

Approaching asteroids: 2022 EM
This giant Apollo-class asteroid approached Earth on Sunday morning around 9 a.m., which is exactly as predicted.
2022 EM flew past the Earth at a distance of 4.41 million miles.
Approaching asteroids: 2022 DT3
2022 DT3 flew past the Earth on Saturday evening around 9:30 p.m. at nearly 20 km/s.
The 71-foot-long asteroid was about 2.33 million miles from Earth.
Approaching asteroids: 2022 DO1
2022 DO1 approached Earth on Saturday evening around 9:40 p.m.
The celestial object measures approximately 48 feet and is less than 1.57 million miles from Earth.
Approaching Asteroids: 2020 DC
First observed on February 16, this small body measures about 51 feet.
Around 4 a.m. Sunday morning, the Apollo-class asteroid approached Earth as its orbit intersects with Earth’s orbit, but it is not considered potentially dangerous.
The house-sized body came 924,000 miles from Earth.
What is a “close approach”?
If an asteroid is within 4.65 million kilometers of Earth and exceeds a certain size, it is considered “potentially dangerous” by cautious space agencies.
Friday’s Next Big Asteroid fits this description.
The asteroid is expected to pass from its safe distance at a speed of just under 19,000 miles per hour.
How big was asteroid 2015 DR215?
Up to 1,607 feet wide, the asteroid is bigger than the Empire State Building.
New York’s most iconic building stands 1,454 feet tall.
NASA monitors thousands of asteroids
NASA has its eye on nearly 28,000 known near-Earth asteroids, and discoveries of new asteroids They are said to increase by thousands every year.
On that note, NASA hopes to launch its Near-Earth Object (NEO) Surveyor mission in 2026.
Nasa updates asteroid software, part four
Previously, scientists had to manually perform calculations to try to determine the Yarkovsky effect and its impact on an asteroid’s trajectory.
The hope is that the software can also help Nasa spot any potentially dangerous asteroids he may have missed.
Nasa updates asteroid software, part 3
Sentry-II software will finally allow scientists to take the Yarkovsky effect into account when trying to understand if an asteroid is going to hit Earth.
This was something the original software, called Sentry, couldn’t do.
Davide Farnocchia, a navigation engineer at JPL, said, “The fact that Sentry couldn’t automatically handle the Yarkovsky effect was a limitation.”
Nasa updates asteroid software, continued
NASA will be update its 20 year old software with a new algorithm called Sentry-II, which will periodically scan an array of known potentially dangerous asteroids and their orbits.
Sentry-II will then calculate if any of the asteroids on the table or added to the table have a chance of hitting Earth.
The new system will take into account what is called the Yarkovsky effect, which refers to when an asteroid absorbs sunlight and emits it as heat.
NASA updates asteroid software
NASA has updated its asteroid danger software to better detect 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 crash into Earth.
There is no known imminent “doomsday asteroid” in its path, but astronomers often check the skies as a precaution.
What are Trojan asteroids?
These asteroids are in the same orbit as a larger planet, but they don’t crash together because they gather around two specific points – the Lagrange points L4 and L5 – in the orbit.
The gravitational pulls of the Sun and the planet are counterbalanced by a Trojan’s propensity to fly out of orbit.
The Jupiter Trojans are the most numerous of the Trojan asteroids.
They are estimated to be as abundant as the asteroids in the asteroid belt.
There are Trojans on Mars and Neptune, and in 2011 NASA reported the discovery of a terrestrial Trojan.
Where are asteroids found?
Asteroids are mainly found in three regions of the solar system.
The majority of asteroids are found in a large ring between the orbits of Mars and Jupiter.
More than 200 asteroids over 100 kilometers in diameter are found in this primary asteroid belt.
According to NASA, the asteroid belt includes between 1.1 million and 1.9 million asteroids larger than a kilometer in diameter, as well as millions of smaller ones.
How do we find asteroids, continued
NASA has been running a near-Earth asteroid research and tracking program since around 2000.
According to CNEOSprograms like the Catalina Sky Survey in Arizona and the Pan-STARRS telescopes in Hawaii specialize in locating asteroids and have identified hundreds of them.
How are asteroids found?
Giuseppe Piazzi, Italian priest and astronomer, accidentally found Ceres, the first and largest asteroid, orbiting between Mars and Jupiter, while drawing a star map in 1801.
Ceres, while today classified as a dwarf planet, is responsible for a quarter of the mass of all known asteroids in or around the Main Asteroid Belt.
Did an asteroid kill the dinosaurs?
The extinction of the dinosaurs was caused by an asteroid impact, according to a team of scientists who were assessing whether the new theory that volcanoes led to their demise was accurate.
The researchers used a variety of methods to assess ancient temperature records and the amount of greenhouse gases that might have been in the atmosphere.
According to the study’s results, volcanic gases may also have played a role in the decline of the dinosaurs.
What is a meteorite?
If a meteoroid enters the Earth’s atmosphere, it begins to vaporize and becomes a meteor.
On Earth, it will look like a streak of light across the sky, as rock burns, and it can look like a ball of fire or a “shooting star”.
If a meteoroid does not completely vaporize and survive the trip through Earth’s atmosphere, it may land on Earth and become a meteorite.
Difference Between Asteroids, Meteors and Comets Part Three
Like asteroids, a comet orbits the Sun.
However, rather than being made mostly of rock, a comet contains a lot of ice and gas, which can cause amazing tails to form behind them due to the vaporization of ice and dust.
“They are anywhere from a few miles to tens of miles wide, but as they orbit closer to the Sun they heat up and spew gas and dust into a glowing head that may be larger than a planet. “, he added. NASA reported.
Difference between asteroids, meteors and comets, continued
When two asteroids collide, the small pieces that break off are called meteoroids.
“Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as ‘space rocks'” NASA reported.
Difference Between Asteroids, Meteors and Comets
An asteroid is a small rocky body that orbits the Sun.
They are “rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago.” NASA reveals.
Most are in the asteroid belt (between Mars and Jupiter).
But they can be found anywhere, including in a path that can impact Earth.
Asteroids often come close to Earth
Asteroids very close to Earth are quite common.
Nasa has previously revealed that car-sized asteroids hit Earth’s atmosphere at least once a year, but burn up before they hit the ground.
And many asteroids are hard to spot because they can be in blind spots created by the Sun.
NASA recently launched its Asteroid Double Redirection Test Mission.
NASA noted: “DART is the very first mission dedicated to the study and demonstration of a method of deflecting asteroids by modifying the movement of an asteroid in space by kinetic impact.”
How many NEAs have been located?
Astronomers have discovered 28,266 near-Earth asteroids as of February 14, 2022, of which 10,033 are 460 feet (140 meters) or more in diameter, and 888 are at least 1 km wide.
