Seeker/DNews on asteroids for Apophis Day 2018

Once again, it's Apophis Day, when I observe the perils of space.  I'm having the same issues with finding videos for today that I did for the seventh anniversary of Fukushima -- too many conspiracy theories about asteroid near misses -- so I'm responding the same way by using older videos from Seeker/DNews.

I begin with How Often Do Asteroids Almost Hit Earth?

Early this week, an asteroid flew right by the Earth, but didn’t hit us. How common is it for objects to fly this close to Earth? Turns out, it’s a lot more common than you’d think.
It was seeing conspiracy theory videos about an asteroid fly-by in February that made me decide to turn to a reliable source that actually paid attention to the science.

A few months later, Seeker/DNews uploaded What Happens When A Meteor Strikes Earth?

Most of the near earth objects that approach Earth burn up in our atmosphere. What happens to the ones that don’t?
Who needs alarmism when the truth is scary enough?

Finally, here is some cool news from last year about an asteroid that isn't going to hit Earth or be seen ever again, An Interstellar Asteroid Just Flew Past Earth, Here’s What You Need to Know.

In October, astronomers observed an interstellar asteroid for the first time. We talked to one of the first to study it, and here’s everything they’ve learned in the months since.
The first thing that struck me is that it looked like the fictional interstellar spacecraft Rama.  Fortunately, it's no such thing.

Enough DOOM.  Tomorrow is another March for Science.  Stay tuned.
