Did NASA-ATLAS miss a 89–200 metre wide asteroid passing close to Earth on June 5?

Recently, a massive asteroid passed between Earth and moon at a distance of 306,000 km from Earth. However, astromers h idea about it until it actually passed Earth on June 5. Re on to kw more about this massive asteroid that NASA-ATLAS came to kw of two days after it actually passed.

Asteroid 2020LD was missed by NASA on June 5?

This asteroid is w claimed to be largest asteroid to pass near Earth in as long as nine years. According to Purdue University's researchers and impact predictor, asteroid would actually have me a nuclear-size explosion h it hit Earth. NASA-ATLAS system does a good job of detecting PHAs (potentially hazardous asteroids) and has detected 46 of se as of w. Even though 2020 LD is t considered as a PHA, but still it was a miss on ATLAS' part. 

data from NASA tells that asteroid which was named 2020LD was actually discovered on June 7. This means that NASA  detected asteroid 2 days after it actually travelled between earth and moon. Asteroid 2020LD was 80 – 200 metres wide and its distance from earth was 306,000 km when it passed on June 5.

This asteroid which was detected by a telescope in Hawaii’s ATLAS system, missed this possibly devastating asteroid when it passed by Earth on June 5. ATLAS system refers to Asteroid Terrestrial-impact Last Alert System which is a NASA funded project. It specifically supervises for any massive asteroids to be near earth’s vicinity that can actually destroy earth’s cities or planets. NASA has a twitter handle where y inform about such asteroid scares as well. Take a look.

Previous asteroid scares

Before this, an asteroid scare happened in 2019 when a 100-meter wide asteroid was finally spotted at last minute. asteroid was called OK and it was deemed as a potential city killer. It passed within 73,000 kilometres of Earth. meteor which was deemed to have wiped out disaurs was 16km wide. However, this near-miss asteroid that passed between earth and moon on June 5 recently is said to be of between 89 – 200 metres wide. Apparently according to EarthSky reports, if this asteroid did hit earth while passing, it might have caused a kilometre wide crater that one can see in Flagstaff, Arizona, USA.

How will NASA deflect potentially hazardous asteroids

Currently, re are two ways kwn to be planned by NASA to deflect or decrease intensity of hazardous asteroids approaching earth. two ways are using a Nuclear bomb or a kinetic impact. Eir a nuclear bomb would be launched to blast asteroid away or a kinetic impactor that is a craft or a rocket to collide with PHA and considerably push it off course from earth. NASA is planning to use a kinetic impactor for asteroid named Psyche in 2026.
