An Asteroid flew very very close to Earth last week, we are lucky he missed us. we couldn’t spot it until 3 days later. which is a pretty terrifying reminder about the dangers asteroids pose to our world.
i just can’t imaging the end of humanity could be because of An Asteroid.
Asteroid 2017 001 Just skimmed Earth
Asteroid 2017 001 was about 37 to 77 meters (121 to 252 feet) across. It came about a third as close as the Moon, 123,031 kilometers (76,448 miles) from our planet Earth , which is a pretty safe distance. It flew past at some point in the night of July 20 at a speed of about 10.36 kilometers (6.4 miles) per second.
we couldn’t spot the asteroid until july 23, after it had passed Earth, and it was spotted by the ATLAS-MLO telescope in Hawaii.
Earth Might be in Danger
Scientists need to do better job detecting even small-sized asteroids early before it turns into a disaster. and “Asteroid 2017 001” is a reminder of what would happen in the future.
Nasa Researchers should raise awareness about asteroids, and what it can cause to our planet Earth, while small asteroids can cause significant regional damage. we are the only species that can do something to prevent that. just Ask the Dinosaurs!.
Asteroids from the History
For a bit of comparison, the Chelyabinsk meteor that exploded over Russia in 2013 was about just 20 meters (65 feet) across. That injured hundreds, and caused considerable damage including shattering windows.
The famous Tunguska meteor In 1908 – measuring 50 to 100 meters (165 to 330 feet) across – exploded over Siberia. the meteor flattened about 80 million trees over an area of 2,000 square kilometers (770 square miles), although fortunately no one was killed. That’s almost the area of Luxembourg.
what would we do to prevent damage of asteroids ?
We know of about 75 percent of asteroids larger than 1 kilometer (0.6 miles) in Earth’s vicinity, deemed as being able to cause extinction events. More alarmingly, we only know about 0.5 percent of asteroids smaller than 120 meters (390 feet). These could cause pretty major damage if they hit Earth.
Asteroid 2017 001 did not hit Earth. However, it should be a pretty good reminder that we need to do more to detect asteroids. Currently, most of our data comes from NASA’s WISE telescope in orbit, which has found thousands of asteroids since 2009 – but not nearly enough.
What would we do if one was coming our way? Well, there are a number of ideas, such as using an impactor to slightly change the trajectory of one. Sadly, ESA scrapped its involvement in a mission to test this out. Hopefully, the threat will be taken seriously in the future.
The dinosaurs didn’t have a space program but Humans do, so lets just avoid any damage could be caused by asteroids.
