NASA NASA asteroid collision warning?

Yup. Newspapers have it. Again. Note the example "news" article with a very tiny disclaimer.
Here are wikipedia's take, some NASA information, and a news article. They are all links and therefore are transient and could change.

https://en.wikipedia.org/wiki/2018_LF16

2018 LF16 is a near Earth asteroid, discovered on June 14, 2018. Its estimate size of 213 m (699 ft) would make it extremely destructive if it collided with the earth.

In November 2018, news articles reported an exaggerated claim of 62 potentially dangerous Earth crossings in the next century; however, its observation arc extends only 2 days, leaving large uncertainties in its prediction motion.

Its current best orbital parameters leaves it entirely outside of the Earth's orbit, and there are no predicted encounters that would change its orbit in the near future.

It is placed 7862th on Near-Earth Asteroid Tisserand Parameters list.

Shows a nice graphic and after a flashy collision disaster headline,
there is tiny disclaimer to the effect that the collision risk is very low:
