asteroid-2020-qg-closest-on-record

A newly-discovered asteroid designated 2020 QG flew past Earth at just 0.02 LD / 0.0000623 AU (9 319 km / 5 791 miles) on August 16, 2020.

This is now the closest near-Earth object to flyby Earth so far this year and the closest on record. 

Valid 15:38 UTC on August 18, 2020

Asteroid 2020 QG has an estimated diameter between 2.9 and 6.4 m (9.5 – 20.9 feet) and it belongs to the Apollo group of asteroids.

It was first observed at Palomar Mountain–ZTF, California, U.S. on August 16, about 6 hours after its closest approach.

The object flew past us at 04:09 UTC at a speed (relative to the Earth) of 12.33 km/s.

  1. THE COMPANION OF THE SUN (THE BROWN DWARF) IS MUCH HARDER TO DETECT THAN AN ASTEROID………………………….Detecting brown dwarfs is much harder than detecting asteroids. Therefore, the companion of our star will become observable only when it gets closer to sun.

  2. Can you see climate deniers? Global warming is also causing the massive increase of the Near-Earth Objects. Mr. Al Gore deserves another Nobel Prize, hahahahahahaha, Lets us have some fun, we are living in the era of hocus pocus science and social chaos, anyway
