Asteroid 2020 HS7 to flyby Earth at 0.11 LD on April 28
A newly-discovered asteroid designated 2020 HS7 will flyby Earth at a very close distance of 0.11 LD / 0.00029 AU (43 383 km / 26 957 miles) at 18:51 UTC on April 28, 2020. This is the 36th known asteroid to flyby Earth within 1 lunar distance since the start of the year and the 11th so far this month. It comes just one day after close approach of 2020 HP6 at a distance of 0.33 LD / 0.00084 AU (125 662 km / 78 082 miles).
This asteroid was first observed at Pan-STARRS 2, Haleakala, Hawaii on April 27, just one day before its close approach.
The object belongs to the Apollo group of asteroids and has an estimated diameter between 4 and 8.9 m (13 – 32.5 feet).

THE NUMBER OF HAZARDOUS ASTEROIDS HAS INCREASED ENORMOUSLY BECAUSE OF MAN-MADE CLIMATE CHANGE! (LOL)…..The number of hazardous Asteroids has increased enormously in the last 20 years. In 1999, there were only a few hazardous Asteroids, but as of March 29, 2020 the number of hazardous Asteroids has reached 2243. However, if you publish a peer reviewed paper claiming that the increase of hazardous Asteroids is due to man-made climate change you will become scientifically famous and the science mafia will provide you with great job.
