NASA Asteroid Warning 2023: 1 Unnoticed
Dubbed 2023 NT1, this space rock, with a width of approximately 200 feet (60 meters), shot past us on July 13, hurtling at an astonishing speed of 53,000 mph (86,000 km/h), as reported by NASA. Surprisingly, the astronomy community remained oblivious to its existence until a whole two days after its celestial encounter.
Reason for Unawareness of Asteroid for 2 Days
- As 2023 NT1 approached Earth from the direction of the sun, the overwhelming brilliance of our star played a trick on us.
- Telescopes scanning the skies were blinded by the Sun’s glare, making it impossible to detect the approaching asteroid until it had safely zipped by.
|Asteroid Passing Earth 2023
|An asteroid as large as a 20-story building zoomed past Earth, unnoticed until 2 days later.
|Reason for Unawareness of Asteroid for 2 Days
|Telescopes were blinded by the Sun’s glare, concealing the approaching asteroid’s presence.
|A Delayed Revelation
|Astronomers spotted the asteroid on July 15 with the help of telescopes, post its close pass.
|No Immediate Threat
|The asteroid poses no immediate danger; research suggests Earth is safe from major impacts.
|The Perils of Sunlit Blind Spots
|Previous incidents show asteroids can slip past detection due to the Sun’s radiant glow.
|Safeguarding Earth’s Future
|The NEOMIR mission aims to address the Sun’s blind spot by searching for hidden asteroids.
A Delayed Revelation of Asteroid Passing Earth 2023
- It wasn’t until July 15 that astronomers spotted the elusive Skyscraper-Size Asteroid rock.
- A telescope situated in South Africa, which is part of the Asteroid Terrestrial-impact Last Alert System (ATLAS) – an array of telescopes designed to identify asteroids days or weeks before any potential impact – managed to capture 2023 NT1 as it bid farewell to our cosmic neighborhood.
- Following this discovery, more than a dozen other telescopes confirmed the rock’s presence, as reported by the International Astronomical Union’s Minor Planet Center.
NASA Asteroid Warning 2023: 3 More Asteroids
According to the Center for Near Earth Object Studies (CNEOS) of NASA, three asteroids are expected to make close approaches to Earth today, July 20, 2023.
The asteroids are:
- 2023 OA: This asteroid is about 50 meters in diameter and will pass by Earth at a distance of about 4.3 million kilometers.
- 2023 OB: This asteroid is about 30 meters in diameter and will pass by Earth at a distance of about 3.6 million kilometers.
- 2023 OC: This asteroid is about 20 meters in diameter and will pass by Earth at a distance of about 3 million kilometers.
All three asteroids are classified as Potentially Hazardous Asteroids (PHAs), which means that they are large enough and have a close enough approach to Earth to be considered a potential threat. However, none of the three asteroids are currently on a collision course with Earth.
The close approaches of these asteroids will be closely monitored by CNEOS and other asteroid tracking organizations. If any of the asteroids were to change course and pose a threat to Earth, there are a number of mitigation strategies that could be used to deflect or destroy the asteroids.
NASA Asteroid Warning 2023: Safeguarding Earth’s Future
- While astronomers keep a close watch on more than 31,000 known near-Earth asteroids, the blind spot caused by the Sun remains a lingering concern.
- To address this potential threat, the European Space Agency is actively working on the NEOMIR mission.
- Scheduled for launch around 2030, NEOMIR will position itself in an orbit between Earth and the Sun, diligently searching for large asteroids that may otherwise remain concealed by our star’s radiant glow.
Frequently Asked Questions(FAQ)
About NASA Asteroid Warning 2023
Q1. How big is the asteroid that makes a skyscraper?
The asteroid is roughly the size of a skyscraper, measuring about 200 feet wide (60 meters).
Q2. What is the largest asteroid ever detected?
The largest asteroid ever detected is Ceres, which is also classified as a dwarf planet. It has a diameter of approximately 590 miles (940 kilometers) and is the largest object in the asteroid belt between Mars and Jupiter.
Q3. How far away can we detect asteroids?
Astronomers can detect asteroids that are several days to weeks away from potential impact with Earth. The Asteroid Terrestrial-impact Last Alert System (ATLAS) and other telescopes can monitor more than 31,000 known near-Earth asteroids. Efforts like the NEOMIR mission aim to improve detection capabilities and search for large asteroids hidden in the Sun’s glare.
Q4. Is the asteroid missing Earth in 2023?
Yes, the asteroid known as 2023 NT1 is missing Earth in 2023. Astronomers have calculated its trajectory for the next decade and determined that there is no imminent risk of an impact on our planet.
Q5. Can a skyscraper reach space?
No, a skyscraper cannot reach space. While skyscrapers can be impressively tall, they are still bound by the Earth’s gravitational pull and atmospheric limitations. Space begins at the Kármán line, approximately 62 miles (100 kilometers) above sea level, which is well beyond the height of any skyscraper.
