Asteroid 2016 QA2 makes exceptionally close Earth flyby hours after discovery

% of readers think this story is Fact. Add your two cents.


Asteroid 2016 QA2 made an exceptionally close flyby of our planet at 01:24 UTC on August 28, 2016, just hours after it was discovered. Its estimated size is 34 meters (111.5 feet), between 16 and 52 meters (52 – 170 feet). This is about twice as big as the asteroid that exploded over Chelyabinsk, Russia in February 2013, injuring over 1 000 people.

At the time of closest approach to our planet, asteroid 2016 QA2 was about 0.22 LD (84 480 km / 52 493 miles) from the surface.

It was discovered by the SONEAR Observatory at Oliveira, Brazil on August 27, as the 24th asteroid in orbit near Earth discovered by SONEAR.

Astronomer Gianluca Masi of the Virtual Telescope Project captured a sequence of 2016 QA2 images. The video is 113X faster than the real motion:


Asteroid 2016 QA2 appears to be an Aten asteroid. This is a group of near-Earth asteroids, named after the first of the group 2062 Aten, discovered by Eleanor F. Helin on January 7, 1967. Aten asteroids are defined by having a semi-major axis of less than one astronomical unit (AU), the distance from the Earth to the Sun. They also have an aphelion (furthest distance from the Sun) greater than 0.983 AU. 

An Aten orbit need not be entirely contained within Earth’s orbit, as nearly all known Aten asteroids have their aphelion greater than 1 AU although their semi-major axis is less than 1 AU. Observation of objects inferior to the Earth’s orbit is difficult and this difficulty may be the cause of some sampling bias in the apparent preponderance of eccentric Atens.

Aten asteroids account for only about 6% of the known near-Earth asteroid population.

The robotic mount tracked the extremely fast (1500″/minute) apparent motion of the asteroid, so stars are trailing. The asteroid is perfectly tracked: it is the bright, sharp dot in the center.

“This is with no doubts a super result, showing the amazing capabilities of the Virtual Telescope in tracking extremely demanding asteroids,” VT said.

Asteroids the size of 2016 QA2 can pose a significant threat to a town or city.

      One of the definitions of a planet is that it clears debris out of its orbit. The asteroids that are close to us, in recent years, were pushed there, by the charge field of Planet X.
