Asteroids, asteroids and asteroids. These days you must be hearing about asteroid. Aren’t you? Asteroids (Space rocks) are small, rocky objects that orbit the Sun. The space rocks (asteroids) approach towards the Earth due to the gravitational forces that affect them. Asteroids can bring tsunamis, shock waves and flattening winds that could be catastrophic. It is said that Earth will reach to its end one day and one of the possible reason for this could be an asteroid. A large number of asteroids are hovering all around the Earth and we might get hit too sooner or later. Yes, you read it right. Well, the life on the Earth would have come to an extinction this August if seven asteroids identified as 2019 ON, 2006 QQ23, 454094 2013 BZ45, 2018 PN22, 2016 PD, 2002 JR100 and 2019 OU1 would have hit our planet. Lucky we are, as they all failed to hit our planet and we are safe.
Asteroid 2019 ON: August 1, 2019
Asteroid 2019 ON came very close to the Earth on August 1. The massive space rock had zip past the Earth at 6:53 am (IST) or 11:23 am (ST) at a speed of 10,400 miles per hour. The closest asteroid 2019 ON to Earth was just under 0.01729 astronomical units or about 1.6 million miles from the Earth’s centre. Well, you can say it was a safe distance, but still much less than the distance between the Earth and Moon.
Asteroid 2006 QQ23: August 10, 2019
Asteroid 2006 QQ23 was the biggest asteroid that approached towards Earth in August this year. Classified as “potentially hazardous”, asteroid 2006 QQ23 was 1,870 feet in diameter while the Empire State Building is 1,454 feet tall. That means the asteroid 2006 QQ23 was around 36 stories larger than the Empire State Building. During its approach towards Earth, the space rock travelled at the staggering speed of 10,400 miles per hour. Asteroid 2006 QQ23 had zip past Earth on August 10 at 7:23 am ST. It was about 0.04977 astronomical units or around 4.6 million miles away from the planet during its flyby.
Asteroid 454094 2013 BZ45: August 12, 2019
Asteroid 454094 2013 BZ45 or Asteroid 2013 BZ45 was about 820 feet long and travelled towards Earth at 18,250 miles per hour. It entered Earth’s neighbourhood on August 12 at 12:14 am ST. Asteroid 2013 BZ45’s closest distance to Earth during its visit was at 0.04352 astronomical units or around 4 million miles away.
Asteroid 2018 PN22: August 17, 2019
Asteroid dubbed as 2018 PN22 approached towards Earth on August 17 at 7:16 pm (ST). Asteroid 2018 PN22 closest distance to Earth during its visit was at0.04385 astronomical units or roughly 4 million miles away. The asteroid was about 62 feet long and traveled at a velocity of 5,000 miles per hour.
Asteroid 2016 PD: August 26, 2019
Asteroid named as 2016 PD1 had zip past the Earth on August 26, 2019 at 7:07 am (ST). The 361-feet asteroid traveled at a speed of 13,100 miles per hour. It had zip past the Earth from a distance of 0.02925 astronomical units or about 2.7 million miles away.
Asteroid 2002 JR100: August 27, 2019
Asteroid 2002 JR100 came close to Earth on August 27. The 269-feet-long space rock had zip past the Earth at 4:07 am (IST) at a speed of 10,400 miles per hour. According to the NASA's Center for Near Earth Object Studies (CNEOS), the closest asteroid 2002 JR100 to Earth was just under 0.04963 astronomical units or roughly 4.6 million miles from the Earth’s centre.
Asteroid 2019 OU1: August 28, 2019
The 500-feet-long asteroid named as 2019 OU1 had zip past the Earth on August 28 at 5:37 am ST from a close distance of only 0.00687 astronomical units or 639,000 miles away. This asteroid traveled at a speed of 30,000 miles per hour.It is worth mentioning here that there are more than 7 lakh asteroids that have been found in space.
