NASA warns of a massive asteroid bigger than the famous London Eye approaching Earth on July 24
- The space boffins in the United States have named it as
Asteroid 2020 ND.
- Asteroid 2020 ND will be almost 50% bigger than the famous London Eye will move past Earth on July 24.
- According to
NASA, asteroid 2020 ND will be as close as 0.034 astronomical units (5,086,328 kilometres) to our planet.
- It is travelling at a great speed of 48,000 kilometres per hour.
The space boffins in the United States have named it as Asteroid 2020 ND. The asteroid is also classified as a potentially hazardous asteroid (PHA) and Near-Earth Object (NEO) by NASA. The asteroid is estimated to be of 120- 260m in diameter. But there isn’t anything to worry about as it won’t be the asteroid’s first-time visiting Earth, it has done that at least five times before as per NASA. It maintains an orbit around the Sun that makes it come close to both Earth and Mars every once in a while.

What are Potentially Hazardous Asteroids?
“Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth. Specifically, all asteroids with an Earth Minimum Orbit Intersection Distance (MOID) of 0.05 au or less and an absolute magnitude (H) of 22.0 or less are considered PHAs,” according to NASA.
What are the Near-Earth Objects (NEO)?
According to NASA, “Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighbourhood. Composed mostly of water ice with embedded dust particles, comets originally formed in the cold outer
The giant outer planets (Jupiter, Saturn, Uranus and Neptune) formed from an agglomeration of billions of comets and the leftover bits and pieces from this formation process are the comets we see today. Likewise, today’s asteroids are the bits and pieces leftover from the initial agglomeration of the inner planets that include Mercury, Venus, Earth and Mars, it further added.
