Personally I would just ask for them to tell me the truth & I can get a deckchair out with a pair of sunglasses
"One day, we are probably going to be faced with a killer asteroid heading our way, threatening to cause major damage to the planet. The odds just aren’t in our favor.
To prepare for such a day, the White House released its Near-Earth Object Preparedness Strategy on December 30, 2016. It details how to stop such a disaster ever occurring, and how to act if worst comes to worst, and we are hit by a large asteroid.
Such events are not unprecedented. Of course, the dinosaurs were wiped out by an asteroid 10 kilometers (6 miles) wide, but many smaller ones hit Earth every day. Most go unnoticed, but some – like the Chelyabinsk meteor over Russia in 2013 – can cause considerable damage.
There are several institutions set up to track these asteroids – such as NASA’s Planetary Defense Coordination Office (PDCO) – but most agree we are not doing enough. We know of thousands of near-Earth asteroids, but more than two-thirds remain undetected.
This new report is by a group that was set up in January 2016 by NASA called Detecting and Mitigating the Impact of Earth-bound Near-Earth objects (DAMIEN). The report recommends enhancing levels of detection asteroids and tracking them, in order to prevent an impact scenario in the future."
