A Kilometer-Vast Asteroid Will Blast Previous Earth This Weekend At An Extraordinary Velocity

This weekend will see the biggest asteroid predicted to go by our planet in 2021 make its closest strategy. It comes simply weeks after the passing of an asteroid nicknamed the ‘God Of Chaos’— and NASA’s telescopes shall be checking it out.

Classed as “doubtlessly hazardous” by astronomers and transferring spectacularly quick, the 0.6 mile/1 kilometer huge 2001 FO32 shall be at its closest to Earth on March 21, 2021.

It’ll go inside 1.25 million miles/2 million kilometers in keeping with NASA’s Jet Propulsion Laboratory

Which may not sound too shut, however that distance is shut sufficient—in astronomical phrases—for 2001 FO32 to be classed as “doubtlessly hazardous.” In addition to, its arrival within the neighborhood of Earth is a really special day for astronomers. Regardless of it passing about 5 occasions additional than the Moon is from Earth, 2001 FO32’s comparatively shut strategy will make it vivid sufficient for astronomers to check it intimately.

Whereas early March’s Asteroid Apophis streaked by Earth at 19 miles/30 km per second, 2001 FO32 shall be transferring at an astonishing 77,000 mph/124,000 kph. 

That’s a lot quicker than most asteroids journey.

Its terrific speeds are the results of its extremely eccentric and elliptical orbital path across the Solar, which is very inclined to Earth and takes it nearer to the Solar than Mercury and twice as removed from the Solar as Mars.

Every time it enters the interior Photo voltaic System to around the Solar it picks up pace, slowing down because it travels in the wrong way.

Little is understood in regards to the nature of 2001 FO32 apart from that it represents a relic of the formation of our Photo voltaic System.

As such, the arrival of 2001 FO32 is a uncommon alternative for astronomers to make use of giant telescopes to get a better have a look at one thing extremely historic. So this weekend, 2001 FO32’s infrared spectrum shall be measured by a ten.5-foot/3.2-meter telescope at NASA’s Infrared Telescope Facility on high of Hawaii’s Mauna Kea. 

That’s vital as a result of current research by NEOWISE (who final yr found “comet of the century” Comet NEOWISE that was seen in July) means that 2001 FO32 is faint within the infrared, so could also be smaller than beforehand thought.

Astronomers may even be attempting to find out what 2001 FO32 is made from—and whether or not it has a moon in orbit.

“Observations relationship again 20 years revealed that about 15% of near-Earth asteroids comparable in dimension to 2001 FO32 have a small moon,” stated Lance Benner, principal scientist at JPL. “At present little is understood about this object, so the very shut encounter gives an excellent alternative to study an amazing deal about this asteroid.”

That’s true of a binary asteroid referred to as Didymos and Didymoon that may go near Earth in October 2022. The Double Asteroid Redirection Take a look at (DART), a mission from NASA and the European House Company (ESA), will launch later this yr and crash into the moon, utilizing “kinetic deflection” to barely change the trajectory of each asteroids.

Found in March 2001 by the Lincoln Close to-Earth Asteroid Analysis (LINEAR) program in Socorro, New Mexico, 2001 FO32’s actual orbit has been calculated intimately. That’s why astronomers know that it gained’t get any nearer to Earth than 1.25 million miles this weekend—and never will it threaten Earth for the rest of the twenty first century. 

Asteroid 2001 FO32’s subsequent journey to Earth’s neighbourhood shall be in 2052 when it would go by at about seven lunar distances, or 1.75 million miles (2.8 million kilometers).

Wishing you clear skies and huge eyes.
