If 900-metre Asteroid Ryugu hits Earth, will we survive the awful catastrophe?

In 2014, the Japan Aerospace Exploration Agency (JAXA) sent a spacecraft called Hayabusa2 on a unique mission. The spacecraft was tasked with landing on an asteroid named Ryugu and to collect rock samples from it. The spacecraft successfully completed its mission in 2020 when it returned with rock samples. In addition to collecting samples, the spacecraft also landed rovers, hit it with projectiles and spent months observing it closely. And now, after spending time analyzing the sample, scientists have been able to answer a terrifying question. What would happen if the asteroid Ryugu were to strike the Earth?

The reason scientists are asking this question and are trying to find answers is because of two factors. Most of the time, when estimations around the impact of an asteroid strike is calculated, only the speed of the asteroid and the angle of strike is used to make the calculation. One very important aspect, the composition of the asteroid is often ignored.

But scientists are finding out that not all asteroids are created equal. For example, Ryugu is a rubble-pile asteroid and not a rock hard asteroid. It means how this asteroid will react to the upper atmosphere will be different from how rocky asteroids would.

The second factor is that scientists do not get to analyze and see an asteroid up close which has not been affected by the heat and pressure of entering the atmosphere. This means that the data derived from studying a pristine asteroid can give really important insight into these space rocks.

Asteroid Ryugu has been measured at roughly 900 meters width. As per NASA, any asteroid that is 1 kilometers wide can trigger a global extinction event. But the answer is a little tricky to find in this case.
