Several Asteroids Are Heading Towards Earth – Dealing With Real-Life Threats to


Asteroid Earth Atmosphere

Could it happen?

Don’t look now – but we are currently experiencing a rash of stories about a forthcoming global catastrophe. But in a change from reports of pandemics and climate change, this global catastrophe is produced by the impact of a giant asteroid. Or comet. Or both. This may feel extra ominous given the events in the recent Netflix film “Don’t Look Up,” in which the Earth is threatened by a “planet killer” asteroid.

But how worried should we really be – and what would happen if such a body actually hit us?

It has been my experience that killer asteroids tend to strike in the summer months, when news is thin on the ground. Maybe we are so tired of grim news about the spread of the omicron COVID variant and associated problems that a killer asteroid (or comet) makes a refreshing change.

Some UK newspapers have turned to Nostradamus, the 16th century astrologer. A couple ran stories at the end of 2021 about 2022 being the year in which Nostradamus predicted that the world would end in a giant impact with a body from space. This hook has resulted in tabulations of objects that may (or, more likely, will not) come close to the Earth in 2022.

My favorite list was published by the Sun newspaper, which described five asteroids heading towards the Earth in January alone.

The scary headline and its accompanying image of an Earth in apparent danger is somewhat undermined by the sentences following the image, in which the newspaper states that “all of the forecasted asteroids this year will pass by Earth by a significant distance and is very unlikely they will hit our planet.” We have already missed (or been missed by) the first two asteroids in this list (2021 YQ and 2021 YX) which hurtled by Earth on January 5 at distances of 1.3 and 2.4 million miles, respectively.

No, I didn’t notice them either – and I study asteroids. There are a further three asteroids predicted to pass between 1 and 5 million miles from the Earth in the next few days, ranging in size from that of a car to that of the Statue of Liberty. The one that will get the closest will still be four times as far away as the Moon, so not exactly close calls.

Is ‘Don’t Look Up’ realistic?

Don’t Look Up is an allegory, using the globally catastrophic impact of a “planet killer” for the globally catastrophic impact of climate change. It is a tale of corruption, venality and political and corporate self-interest placed ahead of the health and welfare of humanity. It is also very funny.

Without giving away too many spoilers, the plot focuses around two astronomers (a graduate student and her professor) who discover a comet that will collide with Earth in six months’ time. They try to tell the President of the United States (played gloriously by Meryl Streep), but she is more concerned with the mid-term elections.

The film pokes fun at right-wing US politics, the influence of donations to political parties on policy (and politicians), the increasing capacity for modern technology to collect information about health, habits, and lifestyle and the use of that information by technology giants.

It does…
