“at 20 percent of the distance from the Earth to the moon”

---

The distance from the Earth to the Moon is 238,900 miles.

So the asteroid on February 10th will come within 47,780 miles of the Earth.

That’s a little close. And the Earth’s gravity won’t affect it?

The circumference of the Earth is 24,900 miles. This is coming within 50,000 miles of the Earth’s surface.

I wonder what warning we will have if one looks like it will hit us? Was there a warning for the one that hit Russia?
